High‐Throughput Screening of Electrocatalysts for Nitrogen Reduction Reactions Accelerated by Interpretable Intrinsic Descriptor

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(19)

Published: March 9, 2023

Developing easily accessible descriptors is crucial but challenging to rationally design single-atom catalysts (SACs). This paper describes a simple and interpretable activity descriptor, which obtained from the atomic databases. The defined descriptor proves accelerate high-throughput screening of more than 700 graphene-based SACs without computations, universal for 3-5d transition metals C/N/P/B/O-based coordination environments. Meanwhile, analytical formula this reveals structure-activity relationship at molecular orbital level. Using electrochemical nitrogen reduction as an example, descriptor's guidance role has been experimentally validated by 13 previous reports well our synthesized 4 SACs. Orderly combining machine learning with physical insights, work provides new generalized strategy low-cost while comprehensive understanding structure-mechanism-activity relationship.

Suppressive Strong Metal‐Support Interactions on Ruthenium/TiO₂ Promote Light‐Driven Photothermal CO₂ Reduction with Methane

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(19)

Published: March 10, 2023

Strong metal-support interactions (SMSI) have gained great attention in the heterogeneous catalysis field, but its negative role regulating light-induced electron transfer is rarely explored. Herein, we describe how SMSI significantly restrains activity of Ru/TiO2 light-driven CO2 reduction by CH4 due to photo-induced electrons from TiO2 Ru. In contrast, on suppression -H2 achieves a 46-fold conversion rate compared . For , considerable number photo-excited hot Ru nanoparticles (NPs) migrate oxygen vacancies (OVs) and facilitate activation under illumination, simultaneously rendering Ruδ+ deficient better able accelerate decomposition. Consequently, photothermal over lowers energy overcomes limitations purely thermal system. This work offers novel strategy for designing efficient catalysts two-phase interactions.
