Remarkably, the methanol yield exceeded 1800 mmolCH3OH\/molCu\/h at 623 K. Typically, the presence of trace oxygen in the system was the key to maintaining the high selectivity to methanol. Characterization results from a series of techniques, including XRD, SEM, TEM, H2-TPR, NH3-TPD, UV-vis, and FTIR, indicated that Cu2+ existed in the position where it moves from hexagonal rings to elliptical cages as the active center.<\/jats:p>","DOI":"10.3390\/molecules29102273","type":"journal-article","created":{"date-parts":[[2024,5,13]],"date-time":"2024-05-13T09:28:25Z","timestamp":1715592505000},"page":"2273","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["One-Pot Cu\/SAPO-34 for Continuous Methane Selective Oxidation to Methanol"],"prefix":"10.3390","volume":"29","author":[{"given":"Lanlan","family":"Sun","sequence":"first","affiliation":[{"name":"Department of Application Chemistry, College of Biotechnology and Food Science, Tianjin University of Commerce, Tianjin 300134, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering and National Institute for Advanced Materials, Nankai University, Tianjin 300350, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuesong","family":"Gu","sequence":"additional","affiliation":[{"name":"Department of Application Chemistry, College of Biotechnology and Food Science, Tianjin University of Commerce, Tianjin 300134, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meng","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Application Chemistry, College of Biotechnology and Food Science, Tianjin University of Commerce, Tianjin 300134, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijuan","family":"Yuan","sequence":"additional","affiliation":[{"name":"Department of Application Chemistry, College of Biotechnology and Food Science, Tianjin University of Commerce, Tianjin 300134, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6894","DOI":"10.1021\/acscatal.8b00220","article-title":"Direct methane to methanol: The selectivity-conversion limit and design strategies","volume":"8","author":"Latimer","year":"2018","journal-title":"ACS Catal."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"6359","DOI":"10.1021\/acs.chemrev.2c00439","article-title":"Methane oxidation to methanol","volume":"123","author":"Dummer","year":"2023","journal-title":"Chem.
