Single-atom catalysts (SACs) have attracted considerable attention in heterogeneous catalysis because of their well-defined active sites, maximum atomic utilization efficiency, and unique unsaturated coordinated structures. However, effectiveness is limited to reactions requiring sites containing multiple metal atoms. Furthermore, the loading amounts single-atom must be restricted prevent aggregation, which can adversely affect catalytic performance despite high activity individual The introduction nanoscale particles (NMPs) into SACs (NMP-SACs) has proven an efficient approach for improving performance. A comprehensive review urgently needed systematically introduce synthesis, characterization, application NMP-SACs mechanisms behind superior This first presents classifies different through NMPs enhance SACs. It then summarizes currently reported synthetic strategies state-of-the-art characterization techniques NMP-SACs. Moreover, electro/thermo/photocatalysis, reasons are discussed. Finally, challenges perspectives future design advanced addressed.

Electrochemical conversion of NO3– into NH3 (NO3RR) holds an enormous prospect to simultaneously yield valuable and alleviate pollution. Herein, we report monodispersed Bi-doped FeS2 (Bi–FeS2) as a highly effective NO3RR catalyst. Atomic coordination characterizations Bi–FeS2 disclose that the isolated Bi dopant coordinates with its adjacent Fe atom create unconventional p–d hybridized Bi–Fe dinuclear sites. Operando spectroscopic measurements combined theoretical calculations sites can synergistically enhance hydrogenation energetics NO3–-to-NH3 pathway, while suppressing competitive hydrogen evolution, leading high selectivity activity. Consequently, specially designed flow cell equipped exhibits rate 83.7 mg h–1 cm–2 near-100% Faradaic efficiency at ampere-level current density 1023.2 mA cm–2, together excellent long-term stability for 100 h electrolysis, ranking almost highest performance among all reported catalysts.

Recycling waste plastics requires the degradation of into small molecules. However, various products are widely distributed using traditional methods depolymerizing polystyrene (PS) such as catalytic pyrolysis and hydrogenolysis. Here, we creatively report a N-bridged Co, Ni dual-atom (Co-N-Ni) catalyst for targeted conversion PS to ethylbenzene via pressurized tandem fixed-bed reactor where hydropyrolysis is coupled with downstream vapor-phase hydrotreatment. The Co-N-Ni achieves 95 wt % 92 yield, significantly superior corresponding single-atom catalysts, enables real plastics. Theoretical calculations experimental results demonstrate that d-band center metal atoms well regulated in catalyst. Co site activates C═C bond more easily, while spatially optimizes adsorption configuration styrene molecule due electronic interaction. This also shows excellent durability provides new direction plastic degradation.
