Trash or treasure? Sustainable noble metal recovery

Abstract

The noble metals, owing to their unique properties, find extensive applications in various modern industry. However, as non-renewable resources, the reserves of noble metals in the natural environment are limited....

Functional high-entropy alloys: promising catalysts for high-performance water splitting

“…To date, Pt group nanomaterials are the most efficient electrocatalysts for the HER. 119 Wu et al synthesized the Pt group metal IrPdPtRhRu HEAs by a facile one-pot polyol process, which required much lower HER overpotentials than the monometallic noble metal catalyst. 71 Establishing a relationship between the electronic structure, specifically the valence band (VB) spectrum, and catalytic activity was a significant development in understanding the fundamental properties of catalysts.…”
