With Jiangsu Normal University as the firstsignature unit, Associate Professor Han Xiguang, from School of Chemistry &Materials Science led his Research Team, cooperating with Professor Zhao Yanlinfrom Nanyang Technological University and published a paper titled “Double-shelledhollow rods assembled from nitrogen/sulfur-codopedcarbon coated indium oxidenanoparticles as excellent photocatalysts” in Nature Communications on May 22. Dr. Sun Liming and postgraduatestudent Li Rong from School of Chemistry & Materials Science contributedequally to this work as first authors. Associate Professor Han Xiguang is thecorresponding author.
NatureCommunication, the top international comprehensiveacademic journal, with 5-Year Impact Factor of 13.7, has a great significancein all research fields.
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.
