METAL catalystsOXYGEN reductionDuring the past few years, single‐atom catalysts (SACs) have attracted considerable attention in electrolysis due to their outstanding catalytic performance and efficient atomic utilization. SACs exhibit a simple structure, high catalytic activity, consistent scal...
Over the past decade, single-atom catalysts (SACs) have been intensively investigated in the field of heterogeneous catalysis. However, SACs only contain one metal center, which makes it difficult to break the scaling relationship in many catalytic processes. In recent years, it has...
Mn-based catalysts have exhibited promising performance in low-temperature selective catalytic reduction of NOx with NH3 (NH3-SCR). However, challenges such as H2O- or SO2-induced poisoning to these catalysts still remain. Herein, we report an efficient strategy to prepare the dual single-atom Ce...

摘要: Single-atom catalysts (SACs) can achieve the maximum metal atom utilization, which exhibit great potential for the chemical transformation of CO2. However, an isolated single active site is less sa...收藏 引用 批量引用 报错 分享
Dual-atom catalysts, particularly those with heteronuclear active sites, have the potential to outperform the well-established single-atom catalysts for oxygen evolution reaction, but the underlying mechanistic understanding is still lacking. Herein, a l
Single-atom catalysts (SACs),23, 24, 25, 26 a new frontier in heterogeneous catalysis, which have advantages of both homogeneous and heterogeneous catalysts, are expected to be potential catalysts for the hydrogenation of CO2 to formic acid under ambient conditions. Shao et al.15 demonstrated ...
Single-atom (SA) catalysts provide extensive possibilities in pursuing fantastic catalytic performances, while their preparation still suffers from metal aggregation and pore collapsing during pyrolysis. Here we report a versatile medium-induced infiltra
Covalent organic frameworks (COFs) have emerged as promising platforms for the construction of single-atom and dual-atom catalysts (SACs and DACs), owing to their well-defined structures, tunable pore sizes, and abundant active sites. In recent years, the development of COF-based SACs and DACs...
