Long‐Range Interactions in Diatomic Catalysts Boosting Electrocatalysis

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(52)

Published: Oct. 6, 2022

Abstract The simultaneous presence of two active metal centres in diatomic catalysts (DACs) leads to the occurrence specific interactions between sites. Such interactions, referred as long‐range (LRIs), play an important role determining rate and selectivity a reaction. optimal combination must be determined achieve targeted efficiency. To date, various types DACs have been synthesised applied electrochemistry. However, LRIs not systematically summarised. Herein, regulation, mechanism, electrocatalytic applications are comprehensively summarised discussed. In addition basic information above, challenges, opportunities, future development proposed order present overall view reference for research.

Challenges and Opportunities in Engineering the Electronic Structure of Single-Atom Catalysts

ACS Catalysis, Journal Year: 2023, Volume and Issue: 13(5), P. 2981 - 2997

Published: Feb. 14, 2023

Controlling the electronic structure of transition-metal single-atom heterogeneous catalysts (SACs) is crucial to unlocking their full potential. The ability do this with increasing precision offers a rational strategy optimize processes associated adsorption and activation reactive intermediates, charge transfer dynamics, light absorption. While several methods have been proposed alter characteristics SACs, such as oxidation state, band structure, orbital occupancy, spin, lack systematic approach application makes it difficult control effects. In Perspective, we examine how configuration SACs can be engineered for thermochemical, electrochemical, photochemical applications, exploring relationship activity, selectivity, stability. We discuss synthetic analytical challenges in controlling discriminating possible directions toward closing gap between computational experimental efforts. By bringing topic center, hope stimulate research understand, control, exploit effects ultimately spur technological developments.
