A ‘liquid’ platinum catalyst outperforms solids at low temperature

Platinum is widely used for many catalytic reactions, and because the precious metal is so expensive, efforts have been ongoing to reduce the amount of Pt required to perform reactions. Among these efforts are the use of nano-dispersions, clusters and…

‘Symbiotic’ electrolyzer runs on waste heat

A new steam-fed electrolyzer aims to bridge the gap between liquid-water electrolyzers, many of which require exotic materials and intricate membranes, and solid-oxide electrolyzers, which require superheated steam and temperatures as high as 800°C. This ‘symbiotic’ electrolyzer, developed by Advanced…
