This work systematically studies the hydrothermal conditionsnfor directly synthesizing anatase TiO&lt;sub&gt;2&lt;/sub&gt; nanotubes (ATNTs),nwhich have not been deeply discussed elsewhere. It has been well-knownnthat ATNTs can be synthesized by the calcination of titanate nanotubes.nHerein, we found the ATNTs can be directly synthesized by optimizingnthe reaction temperature and time rather than calcination of titanatennanotubes, where at each temperature, there is a range of reactionntimes in which ATNTs can be prepared. The effect of NaOH/TiO&lt;sub&gt;2&lt;/sub&gt; ratio and starting materials was explored, and it was found thatnATNTs can be prepared only if the precursor is anatase TiO&lt;sub&gt;2&lt;/sub&gt;, using rutile TiO&lt;sub&gt;2&lt;/sub&gt; leads to forming titanate nanotubes.nAs a result, ATNTs produced directly without calcination have excellentnphotocatalytic CO&lt;sub&gt;2&lt;/sub&gt; reduction than titanate nanotubes andnATNTs prepared by titanate calcination.","PeriodicalId":522046,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1753-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147890407","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}
