Iron oxide “oxygen sponge” doubles the efficiency of hydrogen production in green by targeting active sites at atomic level
Thermochemical cycle of Fe-depleted ferrites for hydrogen production via phase conversion mechanisms. Credit:Postech As the world shifted to sustainable energy sources, “green hydrogen” of hydrogen produced without carbon has emerged as a major candidate for clean power. In an important step, the researchers have developed a new iron-based catalyst that more than doubles the conversion efficiency of thermochemical green water…

Oxygen-Stable Biocatalysts from Thermophilic Bacteria Can Increase Hydrogen Production
Credit: Journal of the American Chemical Society (2025). doi: 10.1021/jacs.4c18483 In the absence of air, microorganisms use an enzyme called (FEFE)-hydrogenase to produce hydrogen. However, these enzymes are rapidly destroyed when exposed to air. Currently, a joint effort led by scientists and theoretical chemistry centers at Ruhr University Bochum, Germany, has isolated a new type of oxygen stability (FEFE)-hydrogenase and…

Zeolite catalysts enable sustainable production of biodegradable plastic materials
Dimethoxymethane (DMM) carbonylation provides a mild, green, sustainable route to the production of glycolic acid, a degradable plastic monomer. ZEO-1 zeolite contains a large cage composed of 16×16 and 16×12 MRS crossings, with a small cage composed of high DMM carbonylation activity and a 12×12 MRS crossing section showing high DMM imbalance activity. Zeolite Zeo-1 exhibits both high DMM carbonylation…
