Achieving high-performance nitrate electrocatalysis with PdCu nanoparticles confined in nitrogen-doped carbon coralline

Abstract

Complex porous carbon nanostructures with homogeneously embeded nanoparticles and intricate architectures render significant promising in developing high-performance catalyst. Herein, we demonstrate a direct surfactant co-assembly approach for the fabrication of well-dispersed PdCu nanoparticles encapsulated in N-doped porous carbon with three-dimensional coralline structures. Owing to the porous feature and unique framework, PdxCuy@N-pC coralline-like nanostructures offer large surface areas, accessible active sites, and excellent nitrate electro-catalysis ability. The composite catalyst Pd4Cu4@N-pC exhibits outstanding catalytic performances, acheving a high nitrate removal rate of ~ 95 % and selectivity of nitrogen of ~ 80 %, and with removal capacity of 22000 mg N/ g PdCu. More importantly, the present work opens up a broad horizon for architectures of nanoparticles confined in coralline-like 3D porous carbon structures, realizing superior performance and promising large scale applications.
