In the field of a heterogeneous industrial catalysis process, the encapsulated structure plays a crucial role in preventing active sites from leaching during the reaction; however, related studies on the strategy to fabricate encapsulated catalysts under control remain rare. Herein, we develop an amino-assisted strategy to construct a highly stable catalyst with core-shell copper nanoparticles (NPs), namely, Cu@NC (NC represents the nitrogen-doped carbon), presenting not only excellent activity but also high durability on the hydrogenation of quinolines even in the large-scale tests, which is very vital in practical application. In contrast, in the absence of the amino group, the Cu NPs were dispersed out of the carbon surface to form Cu/NC, leading to readily lose activity in the recycling tests due to the leaching occurred during the catalytic process.

The exploration of efficient and low-consumption catalysts for carbon dioxide (CO) conversion is desirable yet remains a great challenge. Herein, a novel catalyst composed of a hollow nitrogen-doped carbon framework (HNF) enriched with high-loading (9.8 wt %) atomically dispersed iron sites (defined as ) has been fabricated by a polymer-assisted strategy.

Article Synopsis
  • A new method has been developed to create a hollow structure with specific coordination sites for metal species.
  • This technique produced a highly effective catalyst made of atomically dispersed cobalt sites, which demonstrates excellent performance in converting CO to ethylene carbonate.
  • The approach can also be applied to design other efficient metal catalysts with similar high loading characteristics.
