Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. To determine what was happening, and the best way to make it happen, the Sandia team used computer simulations generated by coauthor Na Sai from the University of Texas at Austin that suggested which molecular changes to seek.

New low-cost bio-inspired nanostructured MoS2 catalyst performs almost as efficiently as Pt for hydrogen production

Green Car Congress

A team led by researchers from Sandia National Laboratories and the University of California, Merced has developed an efficient molybdenum disulfide (MoS 2 ) catalyst for driving the hydrogen evolution reaction (HER). Work at UC Merced was supported by a university startup fund. —Chen et al. Resources.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Cost is a greater concern. We decided we needed to develop a new chemistry if we were going to make low-cost batteries and battery electrodes for the power grid.

Rice, Lawrence Livermore scientists develop new efficient non-Pt MX2 catalyst for efficient hydrogen production; Materials Genome Initiative in action

Green Car Congress

Scientists at Rice University and the Lawrence Livermore National Laboratory have predicted and created new two-dimensional electrocatalysts—low-cost, layered transition-metal dichalcogenides (MX 2 ) based on molybdenum and tungsten—to extract hydrogen from water with high performance and low cost.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

Researchers at the University of Exeter (UK) have developed a novel p-type LaFeO 3 photoelectrode using an inexpensive and scalable spray pyrolysis method. The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability.

This is a sponsored article brought to you by NYU Tandon School of Engineering. However, the research team quickly learned that it was difficult to determine when to travel to field sites to collect flood water samples. A common adage is that if you can measure a thing, you can control a thing, or at least manage it.
