The results indicate that N andnTi3+ was codoped into the lattice of anatase TiO2. The prepared b-N-TiO2, with a narrow bandgap of ∼2.43neV, possesses a three-dimensional (3D) urchinlike nanostructure, whichnis composed of fiberlike architecture with a length of 200–400nnm and a width of 25 nm. The visible-light-driven photocatalytic degradationnrate of Methyl Orange and hydrogen evolution rate for b-N-TiO2 are 95.2% and 178 μmol h–1 g–1, respectively, which are ∼3 and ∼8ntimes higher than those of pristine TiO2. The excellentnphotocatalytic activity is mainly attributed to synergistic effectnof the N and Ti3+ codoping narrowing the bandgap, and uniquen3D urchinlike architecture favors the separation and transport ofnphotogenerated charge carriers and offers more surface-active sites.","PeriodicalId":523752,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147921407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
