Georgia Tech team’s platinum-graphene fuel cell catalysts show superior stability over bulk platinum

Green Car Congress

Films of platinum only two atoms thick supported by graphene could enable fuel cell catalysts with unprecedented catalytic activity and longevity, according to a study published recently by researchers at the Georgia Institute of Technology, with colleagues from University of Oxford, in the journal Advanced Functional Materials. This graphic shows how the graphene layer in gray provides structure and stability to the two atomic layers of platinum above represented in blue. Credit: Ji Il Choi. Platinum is one of the most commonly used catalysts for fuel cells because of how effectively it enables the oxidation reduction reaction at the center of the technology. But its high cost has spurred research efforts to find ways to use smaller amounts of it while maintaining the same catalytic activity. Although there has been a push to use catalytic systems without platinum, there hasn’t been a system proposed so far that simultaneously matches the catalytic activity and the durability of platinum, said Faisal Alamgir, an associate professor in Georgia Tech’s School of Materials Science and Engineering and the corresponding author of the paper. The Georgia Tech researchers tried a different strategy. In the study, which was supported by the National Science Foundation, they created several systems that used atomically-thin films of platinum supported by a layer of graphene—effectively maximizing the total surface area of the platinum available for catalytic reactions and using a much smaller amount of the precious metal. Most platinum-based catalytic systems use nanoparticles of the metal chemically bonded to a support surface, where surface atoms of the particles do most of the catalytic work, and the catalytic potential of the atoms beneath the surface is never utilized as fully as the surface atoms, if at all. Additionally, the researchers showed that the new platinum films that are at least two atoms thick outperformed nanoparticle platinum in the dissociation energy, which is a measure of the energy cost of dislodging a surface platinum atom. That measurement suggests those films could make potentially longer-lasting catalytic systems. Graphene?templated monolayer/few?multilayers of Pt, synthesized as contiguous 2D films by room temperature electrochemical methods, is shown to exhibit a stable {100} structure in the 1–2 layer range. The fundamental question being investigated is whether surface Pt atoms rendered in these 2D architectures are as stable as those of their bulk Pt counterparts. Unsurprisingly, a single layer Pt on the graphene (Pt_1ML/GR) shows much larger Pt dissociation energy (?7.51 eV) than does an isolated Pt atom on graphene. However, the dissociation energy from Pt_1ML/GR is similar to that of bulk Pt(100), ?7.77 eV, while in bi?layer Pt on the graphene (Pt_2ML/GR), this energy changes to ?8.63 eV, surpassing its bulk counterpart. At Pt_2ML/GR, the dissociation energy also slightly surpasses that of bulk Pt(111). Bulk?like stability of atomically thin Pt–graphene results from a combination of interplanar Pt—C covalent bonding and inter/intraplanar metallic bonding. This unprecedented stability is also accompanied by a metal?like presence of electronic states at the Fermi level. Such atomically thin metal?graphene architectures can be a new stable platform for synthesizing 2D metallic films with various applications in catalysis, sensing, and electronics. —Choi et al. To prepare the atomically-thin films, the researchers used a process called electrochemical atomic layer deposition to grow platinum monolayers on a layer of graphene, creating samples that had one, two or three atomic layers of atoms. The researchers then tested the samples for dissociation energy and compared the results to the energy of a single atom of platinum on graphene as well as the energy from a common configurations of platinum nanoparticles used in catalysts. The researchers found that the bond between neighboring platinum atoms in the film essentially combines forces with the bond between the film and the graphene layer to provide reinforcement across the system. That was especially true in the platinum film that was two atoms thick. Typically metallic films below a certain thickness are not stable because the bonds between them are not directional, and they tend to roll over each other and conglomerate to form a particle. But that’s not true with graphene, which is stable in a two-dimensional form, even one atom thick, because it has very strong covalent directional bonds between its neighboring atoms. So this new catalytic system could leverage the directional bonding of the graphene to support an atomically-thin film of platinum. —Faisal Alamgir. Future research will involve further testing of how the films behave in a catalytic environment. The researchers found in earlier research on graphene-platinum films that the material behaves similarly in catalytic reactions regardless of which side—graphene or platinum—is the exposed active surface. In this configuration, the graphene is not acting as a separate entity from the platinum. They’re working together as one. So we believe that if you’re exposing the graphene side, you get the same catalytic activity and you could further protect the platinum, potentially further enhancing durability. —Faisal Alamgir.

Canada investing $2M in $5.1M project to develop energy-efficient comminution technology for mining: conjugate-anvil-hammer mill (CAHM)

Green Car Congress

Canada’s Minister of Natural Resources Amarjeet Sohi announced a $2-million investment in a $5.1-million Canada Mining Innovation Council (CMIC) initiative to develop an energy-efficient mining technology that could significantly reduce energy consumption at mine sites, cut costs and make remote mining operations more productive. Crushing and grinding rocks into smaller pieces (comminution) is the most energy-consuming activity in a mining operation. This project will test technology to replace conventional crushers and lower emissions, while reducing energy consumption and costs. In the project, CMIC will accelerate a new comminution technology—the conjugate-anvil-hammer mill (CAHM)—from a bench scale to prototype scale, with full testing using ore from Canadian mines. CAHM processes ore more efficiently without grinding media and water, instead using two surfaces that rotate in a conjugate pair. CAHM is a comminution machine invented and patented by Dr. Lawrence Nordell, a renowned comminution expert with great experience in SAG (semi-autogenous grinding) mill optimization, crushers and mill liner design, belt conveying advance design, and DEM modeling. The CAHM consists of two principle parts: a rotating outer ring with a horizontal axis of rotation, called the Anvil ring; and a second ring placed inside the Anvil ring, called the Hammer. As the two rings rotate in unison, they produce impact on rock much like the blacksmith’s anvil and hammer produces impact on horseshoes. Patent application drawing of CAHM. Rocks inserted in a gap atop the Hammer ring and inside the Anvil ring will rotate, fall, or be carried into a diminishing gap. Comminution takes place in the closing gap within the synchronized concurrent rotations of the two rings. Pressure is applied to the ore by the Hammer via hydraulic pneumatic pistons, acting on the hammer shaft similar to how HPGR applies pressure to a bed of particles via the hydraulic-pneumatic system. Ore can be fed from one or both sides. Retainer shields are fitted at the open ends to contain the feed within the compression zone. Top: DEM Model of the CAHM Mill. Bottom: CAHM Mill Breakage Mechanism. Source: Hatch Comminution Technology Appraisal Study (2016). The project will consist of designing and testing a prototype-scale CAHM comminution circuit that will reduce energy consumption by up to 50% compared to the latest technology, High Pressure Grinding Rolls (HPGR). Mining consumes 3-6% of the world’s electricity. The new CAHM technology will reduce a key production cost for Canadian mining operations and significantly impact the design, start up and infrastructure economics of new mining operations in remote areas where power is not readily available. Such significant savings of operating cost have the potential to transition mineral development projects from non-viable to viable. The net result would be new mine projects, jobs and capacity development in Canada’s north. In addition, it is estimated that this technology could reduce the complexity and associated capital cost of a new mining project by 20%-30%. The estimated GHG emission reduction is 1.4MT CO 2 e by 2030. The CAHM development project team includes Hatch, CTTI, COREM, Teck Resources, Agnico Eagle, Glencore XPS, Newmont Goldcorp, and Kinross. This project is funded through Natural Resources Canada’s Clean Growth Program, which invests in clean technology research and development projects in Canada’s energy, mining and forest sectors. The program is a $155-million investment fund that helps emerging clean technologies further reduce their impacts on air, land and water, while enhancing competitiveness and creating jobs. Resources.
