Abstract

Excellent catalytic activity, highstability and easy recovery are three key elements for fabricating efficientphotocatalysts, while developing a simple method to fabricate suchphotocatalysts with these three features at the same time is highlychallenging. In this study, we successfully synthesized double-shelled hollowrods (DHR) assembled by nitrogen (N) and sulfur (S)-codoped carbon coatedindium(III) oxide (In2O3) ultra-small nanoparticles (N,S-C/In2O3 DHR).N,S-C/In2O3 DHR exhibits remarkable photocatalytic activity, high stability andeasy recovery for oxidative hydroxylation reaction of arylboronic acidsubstrates. The catalyst recovery and surface area were well balanced throughimproved light harvesting, contributed by concurrently enhancing the reflectionon the outer porous shell and the diffraction in the inside double-shelledhollow structure, and increased separation rate of photogenerated carriers.Photocatalytic mechanism was investigated to identify the main reactive speciesin the catalytic reactions. The electron separation and transfer pathway viaN,S-codoped graphite/In2O3 interface was revealed by theoretical calculations.
