Recently, various studies related to adsorption materials for reducing formaldehyde have been widely reported. In this study, mesoporous and mesoporous hollow silicas with amine functional groups introduced were utilized as adsorption materials for formaldehyde. Formaldehyde adsorption characteristics of mesoporous and mesoporous hollow silicas having well-developed pores were compared based on their synthesis methods\u2014with or without a calcination process. Mesoporous hollow silica synthesized through a non-calcination process had the best formaldehyde adsorption characteristics, followed by mesoporous hollow silica synthesized through a calcination process and mesoporous silica. This is because a hollow structure has better adsorption properties than mesoporous silica due to large internal pores. The specific surface area of mesoporous hollow silica synthesized without a calcination process was also higher than that synthesized with a calcination process, leading to a better adsorption performance. This research suggests a facile synthetic method of mesoporous hollow silica and confirms its noticeable potential as a support for the adsorption of harmful gases.<\/jats:p>","DOI":"10.3390\/ijms24044208","type":"journal-article","created":{"date-parts":[[2023,2,20]],"date-time":"2023-02-20T05:27:01Z","timestamp":1676870821000},"page":"4208","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Facile Mesoporous Hollow Silica Synthesis for Formaldehyde Adsorption"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2912-9230","authenticated-orcid":false,"given":"Misun","family":"Kang","sequence":"first","affiliation":[{"name":"Department of Chemistry, Keimyung University, Daegu 42601, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jong-tak","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Keimyung University, Daegu 42601, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae Young","family":"Bae","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Keimyung University, Daegu 42601, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"15802","DOI":"10.1088\/0957-0233\/27\/1\/015802","article-title":"A measurement strategy for non-dispersive ultra-violet detection of formaldehyde in indoor air: Spectral analysis and interferent gases","volume":"16","author":"Davenport","year":"2016","journal-title":"Meas.
