Role of the Support Effects in Single‐Atom Catalysts
Chemistry – An Asian Journal, 2023AbstractIn recent years, single‐atom catalysts (SACs) have received a significant amount of attention due to their high atomic utilization, low cost, high reaction activity, and selectivity for multiple catalytic reactions. Unfortunately, the high surface free energy of single atoms leads them easily migrated and aggregated.

Single–Atom Supported Catalysts and Beyond
Advanced MaterialsAbstractTuning electronic configurations of active components in supported metal catalysts can be achieved via strong metal–support interaction (SMSI) between loaded metal species and support, which has a profound effect on catalytic efficiency. Distinct from conventional supports, single–atom catalysts, due to their rich unsaturated coordination metal

Deactivation of Single‐Atom Catalysts by Nanoparticles
Angewandte Chemie International EditionAbstract Single‐atom catalysts (SACs) represent a pinnacle of atomic efficiency and catalytic precision. Their remarkable activity and selectivity arise from isolated, low‐coordinate metal centers that engage directly in bond‐forming events. However, under realistic reaction conditions, SACs are far from static.

Co Single‐Atom Catalysts Boost Chemiluminescence
Chemistry – A European Journal, 2020AbstractCo single‐atom catalysts (SACs) with good aqueous solubility and abundant labelling functional groups were prepared in Co/Fe bimetallic metal‐organic frameworks by a facile solvothermal method without high‐temperature calcination. In contrast to traditional chemiluminescence (CL) catalysts, Co SACs accelerated decomposition of H2O2 to produce a

Single-Atom Saturation: A Fundamental Principle for Single-Atom-Site Catalyst Design
Journal of the American Chemical SocietySingle-atom alloys (SAAs), with twin advantages of alloys and single-atom catalysts, have emerged as an innovative class of electrocatalysts. This uniqueness is expected to achieve unattainable catalytic performance but simultaneously gives rise to the absence of guidelines for designing desired SAAs. Herein, we proposed a fundamental principle, single-
