Direct conversion of methane, the primary component of natural gas, to olefins via methanol as an intermediate is of significant industrial interest. Recent studies demonstrate that methanol can be efficiently synthesized from methane using transition\u2010metal\u2010free aluminosilicate Ferrierite (FER) zeolite with nitrous oxide (N\n                    <jats:sub>2<\/jats:sub>\n                    O)\u00a0as the oxidant. Herein, a tandem catalytic system based on the composite FER and one more acidic zeolite is reported to achieve continuous conversion of methane to olefins. The topology and acidity of acidic zeolites critically influenced product distribution and hydrocarbon formation rates. When small\u2010pore zeolites are used as acidic zeolites, complete conversion of methanol to olefins is successfully achieved. Reaction conditions for methane\u2010to\u2010olefins conversion are optimized\u00a0using\u00a0 silicoaluminophosphate (SAPO\u201034) as a representative acidic zeolite. The\u00a0mass ratio of FER to SAPO\u201034 determined catalytic performance, with\u00a0conversion of methane to light olefins achieving thermodynamic feasibility at 325\u2013400\u00a0\u00b0C. Enhanced intimacy between FER and SAPO\u201034 particles\u00a0promoted methane (CH\n                    <jats:sub>4<\/jats:sub>\n                    ) conversion. This work establishes an efficient strategy for\u00a0high\u2010selectivity light olefin production\u00a0from methane over\u00a0integrated transition\u2010metal\u2010free zeolite catalysts.\n                  <\/jats:p>","DOI":"10.1002\/advs.202515145","type":"journal-article","created":{"date-parts":[[2025,10,14]],"date-time":"2025-10-14T02:51:11Z","timestamp":1760410271000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Transition\u2010Metal\u2010Free Zeolite Composites for Tandem Catalytic Conversion of Methane to Light Olefins"],"prefix":"10.1002","volume":"13","author":[{"given":"Peipei","family":"Xiao","sequence":"first","affiliation":[{"name":"Institute of Integrated Research Institute of Science Tokyo  4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20138501 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroto","family":"Toyoda","sequence":"additional","affiliation":[{"name":"Institute of Integrated Research Institute of Science Tokyo  4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20138501 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuqin","family":"Sun","sequence":"additional","affiliation":[{"name":"Institute of Integrated Research Institute of Science Tokyo  4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20138501 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Integrated Research Institute of Science Tokyo  4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20138501 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hermann","family":"Gies","sequence":"additional","affiliation":[{"name":"Institute of Integrated Research Institute of Science Tokyo  4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20138501 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3315-3172","authenticated-orcid":false,"given":"Toshiyuki","family":"Yokoi","sequence":"additional","affiliation":[{"name":"Institute of Integrated Research Institute of Science Tokyo  4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20138501 Japan"},{"name":"iPEACE223 Inc.
