—Low-Cost Water-Splitting Photocatalyst “” Cadmium sulfide doped with a small amount of molybdenum disulfide serves as an efficient photocatalyst for the water-splitting reaction under visible light, according to researchers at the Dalian Institute of Chemical Physics in China (J. Am. Chem. Soc., DOI: 10.1021/ja8007825).

The team also studied 2-D molybdenum disulfide membranes, which had the densest electron clouds according to the team’s simulations and the poorest proton conductivity according to their measurements. Geim hopes theorists will help solve the remaining mysteries of proton transport, such as why graphene outperforms hBN at elevated temperatures.

Hydrodesulfurization (HDS) catalysts typically consist of small clusters of molybdenum disulfide with low concentrations of cobalt or nickel additives that serve to promote chemical reaction. Some catalyst formulations use tungsten disulfide. Treating heavy crude oil fractions with hydrogen in the presence of HDS catalysts strips the raw material of environmental pollutants by converting sulfur-containing molecules to volatile hydrogen sulfide.

The new materials join the small but growing number of atomically (or nearly atomically) thin materials, such as graphene, boron nitride, and molybdenum disulfide, that are strong enough to be transferred to microscopy grids. These holey supports leave relatively large sections of the films consisting of millions of repeat units suspended over micrometer-sized holes.

Led by Yu Huang of the University of California, Los Angeles, and James De Yoreo of Pacific Northwest National Laboratory, the team used atomic force microscopy and computations to study the mechanism by which peptides in solution form chains and add, row by row, to a growing peptide crystal on a molybdenum disulfide surface.

Various 2-D materials, including black phosphorus and molybdenum disulfide, rank among the top-performing gas-sensing media. That motivated a team led by Hee-Tae Jung of Korea Advanced Institute of Science & Technology and Yury Gogotsi of Drexel University to see how MXenes, a family of 2-D metal carbides and nitrides, stack up in that application.

In the new method, called streaming ionization, the researchers flow an organic alcohol—methanol works best—over filter paper coated with layers of 2D molybdenum disulfide (ACS Nano 2021, DOI: 10.1021/acsnano.0c09985). When an alcohol flows over the surface, the device generates a detectable current, which is produced by the dissociation of solvent molecules and the movement of anions.
