Coordination Engineering of Ultra-Uniform Ruthenium Nanoclusters as Efficient Multifunctional Catalysts for Zinc-Air Batteries.

ABSTRACT: The lack of highly efficient, inexpensive catalysts severely hinders the large-scale application of electrochemical energy conversion technologies (e.g., electrochemical hydrogen evolution reaction (HER) for hydrogen production, metal-air batteries (Cathode: oxygen reduction reaction (ORR))). As a new class of nanomaterials with a high ratio of surface atoms and tunable composition and electronic structure, metal nanocluster (NCs) are promising candidates as catalysts. Herein, a novel catalyst using S,N-doped carbon matrix (NSCSs) is synthesized to efficiently stabilize high density and ultra-uniform ruthenium (Ru) nanoclusters (Ru@NSCSs) by small-molecule self-assembly pyrolysis approach. The obtained Ru@NSCSs catalyst exhibits outstanding HER activity in all pH conditions (especially wit
