Small Methods, Journal Year: 2023, Volume and Issue: unknown

Published: Dec. 31, 2023

Abstract Facing with serious carbon emission issues, the production of green H 2 from electrocatalytic hydrogen evolution reaction (HER) has received extensive research interest. Almost all kinds noble metal phosphides (NMPs) consisting Pt‐group elements (i.e., Ru, Rh, Pd, Os, Ir and Pt) are highly active pH‐universal electrocatalysts toward HER. In this review, recent progress NMP‐based HER is summarized. It further take typical examples for discussing important impact factors on performance NMPs, including crystalline phase, morphology, element doping. Moreover, synthesis application hybrid catalysts NMPs other materials such as transition phosphides, oxides, sulfides phosphates, metals also reviewed. Reducing use key idea electrocatalysts, while expanded functionality structure‐performance relationship noticed in part. At last, potential opportunities challenges kind catalyst discussed.

Single‐Atom Catalysts and Dual‐Atom Catalysts for CO₂ Electroreduction: Competition or Cooperation?

Small, Journal Year: 2023, Volume and Issue: 19(40)

Published: June 2, 2023

Developing highly active and selective electrocatalysts for electrochemical reduction of CO2 can reduce environmental pollution mitigation greenhouse gas emission. Owing to maximal atomic utilization, the atomically dispersed catalysts are broadly adopted in reaction (CO2 RR). Dual-atom (DACs), with more flexible sites, distinct electronic structures, synergetic interatomic interactions compared single-atom (SACs), may have great potential enhance catalytic performance. Nevertheless, most existing low activity selectivity due their high energy barrier. Herein, 15 explored noble metallic (Cu, Ag, Au) sites embedded metal-organic hybrids (MOHs) high-performance RR studied relationship between SACs DACs by first-principles calculation. The results indicated that excellent electrocatalytic performance, moderate interaction single- dual-atomic center improve RR. Four among catalysts, including (CuAu), (CuCu), Cu(CuCu), Cu(CuAu) MOHs inherited a capability suppressing competitive hydrogen evolution favorable CO overpotential. This work not only reveals outstanding candidates MOHs-based dual-atom but also provides new theoretical insights into rationally designing 2D electrocatalysts.
