Switch Volmer‐Heyrovsky to Volmer‐Tafel Pathway for Efficient Acidic Electrocatalytic Hydrogen Evolution by Correlating Pt Single Atoms with Clusters

Small, Journal Year: 2024, Volume and Issue: 20(25)

Published: Jan. 19, 2024

Abstract As cost‐effective catalysts, platinum (Pt) single‐atom catalysts (SACs) have attracted substantial attention. However, most studies indicate that Pt SACs in acidic hydrogen evolution reaction (HER) follow the slow Volmer‐Heyrovsky (VH) mechanism instead of fast kinetic Volmer‐Tafel (VT) pathway. Here, this work propose VH can be switched to faster VT pathway for efficient HER by correlating single atoms (SAs) with clusters (Cs). Our calculations reveal correlation between SAs and Cs significantly impacts electronic structure exposed atoms, lowering adsorption barrier atomic enabling a mechanism. To validate these findings, purposely synthesize three catalysts: l ‐Pt@MoS 2 , m h low, moderate, high Pt‐loading, having different distributions Cs. The m‐Pt@MoS catalyst properly exhibits outstanding performance an overpotential 47 mV Tafel slope 32 dec −1 . Further analysis values confirms sample indeed follows mechanism, aligning theoretical findings. This study offers deep understanding synergistic paving way designing novel‐advanced catalysts.

Ultrafine Iridium Nanoparticles Anchored on Co-Based Metal–Organic Framework Nanosheets for Robust Hydrogen Evolution in Alkaline Media

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(4), P. 2282 - 2288

Published: Jan. 17, 2024

A highly promising electrocatalyst has been designed and prepared for the hydrogen evolution reaction (HER). This involves incorporating well-dispersed Ir nanoparticles into a cobalt-based metal–organic framework known as Co-BPDC [Co(bpdc)(H2O)2, BPDC: 4,4′-biphenyldicarboxylic acid]. Ir@Co-BPDC demonstrates exceptional HER activity in alkaline media, surpassing both commercial Pt/C recent noble-metal catalysts. Theoretical results indicate that electron redistribution, induced by interfacial bonds, optimizes adsorption energy of water hydrogen, thereby enhancing our understanding superior properties HER.
