source:TOHOKU UNIVERSITYA group of researchers has achieved significant progress in developing cost-effective catalysts for the oxygen evolution reaction (OER), a critical component in technologies like water splitting and metal-air batteries. By incorporating chromium (Cr) into transition metal hydroxides, they have demonstrated enhanced catalytic activity using a combination of Density Functional Theory (DFT) calculations and experimental synthesis.Details of their findings were published in the journal ACS Catalysis on August 30, 2024.In recent years, hydrogen production through water elect...

source:TechxploreAs the world transitions away from fossil fuels, the demand for rare earth elements (REEs) is only going to increase. These elements are vital to the production of technologies that will make the transition to green energy possible. While REEs are not technically rare, large deposits are found in only a few locations around the world—mostly in China—and they are difficult to extract."If we want to switch to electric vehicles by 2035 and be net-zero by 2050 we're going to need new sources of these metals," says Brendan Bishop, a Ph.D. candidate studying REEs at th...

source:phys.orgThe synthesis of molybdenum carbide catalysts typically requires high temperature, leading to inevitable passivation in an oxygen-containing atmosphere. Developing a new route to produce molybdenum carbide at low temperatures is challenging but essential to increase the density of surface active sites.In a recent study published in Angewandte Chemie International Edition, a research group led by Prof. BAO Xinhe and Prof. FU Qiang from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) developed an in-situ dynamic carbonization method to synt...
