Single‐atom catalysts (SACs) have emerged to be a new research frontier in catalysis due to their distinctive physical and chemical properties, including better catalytic performance, stability, and recyclability. However, the widely used organic synthesis methods for SACs limit the ability to uniformly distribute single atoms’ water‐soluble precursors on the support of the catalysts. A water‐based synthesis of single gold (Au) atom catalyst is used in this work. Through this method, water‐soluble Au precursors are successfully turned into Au single atoms embedded in metal–organic framework‐derived nitrogen‐containing nanoporous carbon. The resulting catalyst is applied on the reduction of 4‐nitropenol. The catalytic performance of the reaction reaches 100% conversion in 30 min, while utilizing Au nanoparticles as active sites on the same support can only get 70% conversion under the same reaction conditions.

具有增强还原能力的金单原子嵌入的金属有机框架衍生的纳米多孔碳纳米粒子的水基合成

单原子催化剂（SAC）由于其独特的物理和化学特性（包括更好的催化性能，稳定性和可回收性）已成为催化领域的一个新研究领域。但是，广泛使用的SAC有机合成方法限制了将单原子的水溶性前体均匀分布在催化剂载体上的能力。这项工作中使用了水基合成的单金（Au）原子催化剂。通过这种方法，水溶性金前驱体成功地转化为嵌入金属有机骨架衍生的含氮纳米多孔碳中的金单原子。生成的催化剂用于还原4-硝基戊醇。反应的催化性能在30分钟内达到100％的转化率，
