Modifying the electronic structure of catalysts can improve their performance; lattice strain (either compressive or tensile) modifies the distances between surface atoms and hence modifies catalytic activity. The rate of ORR is very slow because molecular oxygen has a very strong double bond that requires significant energy to be broken.

Rafts of catalytic platinum oxide float above aluminum oxide, anchored by bonds between platinum and aluminum. Such precious metal and oxide combinations are the most common kinds of industrial catalysts. The new work will help engineers control the preparation of the catalyst, which will lead to performance improvements.

Recently, it has been proposed that preparing metal germanate nanowires or nanobelts could be a strategy to mitigate these problems. A team from Shandong University in China reported (Feng 2014) preparing PbGeO 3 /polypyrrole (PGO/PPy) nanocomposites. Another approach to PGO anodes. Another approach to PGO anodes. Wang et al.

In their paper, they reported that experimental results and molecular dynamics simulations reveal the synergistic effect between GO and NFC: the bonding between neighboring GO nanosheets is enhanced by NFC because the introduction of NFC provides the extra bonding options available between the nanosheets.

Significant effort has been devoted to the search of non-precious-metal based HER catalysts including sulfide-based materials, and C 3 N 4. The researchers also prepared single Pt atoms on graphene to compare with the samples on N-doped graphene. Schematic illustration of the Pt ALD mechanism on NGNs. Cheng et al. Click to enlarge.

Sandia researchers have developed a new family of electrochemically reversible, metal-based ionic liquid (MetILs) that could lead to non-aqueous redox (reducing-oxidizing) flow-battery energy storage systems ( earlier post ) able to cost-effectively store three times more energy than today’s batteries. Most metal salts, particularly.

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.

However, the exact mechanism that takes place on this material’s surface, and how that reaction is affected by the orientation of the crystal surfaces, had never been determined in detail. Ruthenium dioxide surfaces are currently “the gold standard of catalysts for water splitting,” according to Shao-Horn.

The precious metal facilitates chemical reactions for many commonly used products and processes, such as converting poisonous carbon monoxide to less harmful carbon dioxide in catalytic converters. Atom trapping should be broadly applicable as a method for preparing single-atom catalysts. Jones et al. Click to enlarge.

This two-way split (passenger cell and drive frame) is reflected in the design of the BMW i3—both the exterior and interior make a feature of this structural characteristic through the visible layering and intertwining of different surfaces. All the electricity used to produce the BMW i models at the Leipzig plant is wind-generated.
