The Influence of Ni Content in NixCoy‐BDC Metal‐Organic Frameworks on Catalytic Activity for Hydrogen Generation from Sodium Borohydride

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
ABSTRACT Mono‐ and bimetallic Ni/Co‐based metal–organic frameworks (MOFs) coordinated with 1,4‐benzenedicarboxylate were successfully synthesized via a solvothermal approach and characterized by PXRD, FTIR, TGA, SEM–EDS, TEM, BET, and XPS. Fine control over the Ni:Co molar ratio enabled systematic modulation of the structural and electronic properties ...

Water Consumption in Hydrogen Production Through Electrolysis: Overview, State‐of‐the‐Art, and Future Trends

WIREs Energy and Environment, Volume 15, Issue 2, June 2026.
Commercial‐scale “green” hydrogen projects use renewable electricity to drive electrolysis—the process of splitting water into hydrogen and oxygen. Producing green hydrogen requires water not only for the electrolysis reaction but also for cooling the electrolyzers, which release waste heat.
