Hence, it is imperative to efficiently remove HCHO and create a good indoor living environment for people. Herein, a layered perovskite material SrBi2Ta2O9 (SBT), was studied for the first time and exhibited superior photocatalytic efficiency and stability compared to commercial TiO2 (P25). Furthermore, a unique dark\u2013light tandem catalytic mechanism was constructed. In the dark reaction stage, HCHO (Lewis base) site was adsorbed on the terminal (Bi2O2)2+ layer (Lewis acid) site of SBT in the form of Lewis acid-base complexation and was gradually oxidized to CO32\u2212 intermediate (HCHO \u2192 DOM (dioxymethylene) \u2192 HCOO\u2212 \u2192 CO32\u2212). Then, in the light reaction stage, CO32\u2212 was completely converted into CO2 and H2O (CO32\u2212 \u2192 CO2). Our study contributes to a thorough comprehension of the photocatalytic oxidation of HCHO and points out its potential for day\u2013night continuous work applications in a natural environment.<\/jats:p>","DOI":"10.3390\/molecules28155691","type":"journal-article","created":{"date-parts":[[2023,7,28]],"date-time":"2023-07-28T02:10:45Z","timestamp":1690510245000},"page":"5691","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Dark\u2013Light Tandem Catalytic Oxidation of Formaldehyde over SrBi2Ta2O9 Nanosheets"],"prefix":"10.3390","volume":"28","author":[{"given":"Weimin","family":"Ma","sequence":"first","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Key Laboratory of Chemical Additives for China National Light Industry, Shaanxi University of Science and Technology, Xi\u2019an 710021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qing","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Shaanxi University of Science and Technology, Xi\u2019an 710021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhan","family":"Lin","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Engineering, Shaanxi University of Science and Technology, Xi\u2019an 710021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingxuan","family":"Li","sequence":"additional","affiliation":[{"name":"MIIT Key Laboratory of Critical Materials Technology for New Energy Conversion and Storage, School of Chemistry and Chemical Engineering, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6377","DOI":"10.1002\/anie.202013667","article-title":"Pt\/MnO2 nanoflowers anchored to boron nitride aerogels for highly efficient enrichment and catalytic oxidation of formaldehyde at room temperature","volume":"60","author":"Chen","year":"2021","journal-title":"Angew.
