WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record compiled from open scholarly databases; the abstract is shown in full only where the paper is openly licensed, otherwise a short excerpt under fair use. Classifications are automated and approximate.

Switching N‐N Versus N‐H Couplings in Nitrate Electroreduction With CuPd Surface Atomic Motifs

Keying Wu, Weiyan Wu, Siyuan Liu et al. · 2026 · Angewandte Chemie International Edition

ABSTRACT Nitrate electroreduction reaction (NO 3 − RR) offers a promising solution to address excessive nitrate emissions by converting them into either environmentally benign dinitrogen or useful ammonia. Bimetallic catalysts, such as…
