Robust ultrafine ruthenium nanoparticles enabled by covalent organic gel precursor for selective reduction of nitrobenzene in water

Abstract

Metal nanoparticles (NPs) supported on nitrogen-doped porous carbon (NPC) are one type of promising heterogeneous catalysts, the tuning and understanding of the metal-support interactions are crucial for the design and synthesis of highly durable and efficient heterogeneous catalytic systems. Here, we present an effective strategy to integrate ultrafine metal NPs into NPC through utilizing covalent organic gel (COG) as the precursor for the first time. The ruthenium (Ru) NPs are uniformly dispersed in NPCs with the average size as low as 1.90±0.4 nm. Irrespective of ultrafine size, the Ru NPs show unprecedented stability and recyclability in Ru-catalyzed reduction of nitrobenzene, which are greatly superior to commercial Ru/C and NPC-supported Ru NPs synthesized by traditional post-loading method. This synthetic strategy can be extended to the synthesis of other metal or alloy NPs for a variety of advanced applications.
