The development of new technologies for the elimination of VOCs, especially those from non-industrial emission sources, such as indoor air pollution and other low-concentration VOCs exhaust gases, is essential for improving environmental quality and human health. In this study, a monolithic photothermocatalyst was prepared by stabilizing manganese oxide on multi-porous carbon spheres to facilitate the elimination of formaldehyde (HCHO). This catalyst exhibited excellent photothermal synergistic performance. Therefore, by harvesting only visible light, the catalyst could spontaneously heat up its surface to achieve a thermal catalytic oxidation state suitable for eliminating HCHO. We found that the surface temperature of the catalyst could reach to up 93.8 \u00b0C under visible light, achieving an 87.5% HCHO removal efficiency when the initial concentration of HCHO was 160 ppm. The microporous structure on the surface of the carbon spheres not only increased the specific surface area and loading capacity of manganese oxide but also increased their photothermal efficiency, allowing them to reach a temperature high enough for MnOx to overcome the activation energy required for HCHO oxidation. The relevant catalyst characteristics were analyzed using XRD, measurement of BET surface area, scanning electron microscopy, HR-TEM, XPS, and DRS. Results obtained from a cyclic performance test indicated high stability and potential application of the MnOx-modified multi-porous carbon sphere.<\/jats:p>","DOI":"10.3390\/ma15134484","type":"journal-article","created":{"date-parts":[[2022,6,26]],"date-time":"2022-06-26T21:01:41Z","timestamp":1656277301000},"page":"4484","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Efficient Photothermal Elimination of Formaldehyde under Visible Light at Room Temperature by a MnOx-Modified Multi-Porous Carbon Sphere"],"prefix":"10.3390","volume":"15","author":[{"given":"Wanpeng","family":"Liu","sequence":"first","affiliation":[{"name":"Power China Huadong Engineering Corporation, Hangzhou 311122, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liu","family":"Shi","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Key Laboratory of Surface & Interface Science of Polymer Materials of Zhejiang Province, Zhejiang Sci-Tech University, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongyang","family":"Yin","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Key Laboratory of Surface & Interface Science of Polymer Materials of Zhejiang Province, Zhejiang Sci-Tech University, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengfei","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Key Laboratory of Surface & Interface Science of Polymer Materials of Zhejiang Province, Zhejiang Sci-Tech University, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinming","family":"Ren","sequence":"additional","affiliation":[{"name":"Power China Huadong Engineering Corporation, Hangzhou 311122, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongming","family":"Wang","sequence":"additional","affiliation":[{"name":"Power China Huadong Engineering Corporation, Hangzhou 311122, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1059","DOI":"10.1016\/j.cclet.2012.06.015","article-title":"Increase of ambient formaldehyde in Beijing and its implication for VOC reactivity","volume":"23","author":"Zhang","year":"2012","journal-title":"Chin.
