This reaction is particularly interesting for the direct upgrading of biogas, which mainly contains methane and carbon dioxide, into biomethane. This work focused on the synthesis and evaluation of natural clay-supported nickel catalysts in the catalytic methanation reaction. Natural clay could be directly used as a low-cost catalyst support for the deposition of small nickel nanoparticles (1\u201315 nm) by the standard incipient wetness impregnation method. These catalysts showed high activity and excellent selectivity into methane and excellent catalytic stability (80% carbon dioxide conversion, nearly 100% methane selectivity at 500 \u00b0C, 1 bar, and WHSV = 17,940 mL\u00b7gcat\u22121\u00b7h\u22121 for 48 h on stream) and outperformed their counterparts prepared with an industrial alumina support as reference.<\/jats:p>","DOI":"10.3390\/molecules30102110","type":"journal-article","created":{"date-parts":[[2025,5,9]],"date-time":"2025-05-09T08:20:23Z","timestamp":1746778823000},"page":"2110","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Catalytic Methanation over Natural Clay-Supported Nickel Catalysts"],"prefix":"10.3390","volume":"30","author":[{"given":"Alejandra","family":"Cue Gonzalez","sequence":"first","affiliation":[{"name":"Centre RAPSODEE, IMT Mines Albi, UMR CNRS 5302, Universit\u00e9 de Toulouse, Campus Jarlard, CEDEX 09, 81013 Albi, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1513-5074","authenticated-orcid":false,"given":"Elsa","family":"Weiss-Hortala","sequence":"additional","affiliation":[{"name":"Centre RAPSODEE, IMT Mines Albi, UMR CNRS 5302, Universit\u00e9 de Toulouse, Campus Jarlard, CEDEX 09, 81013 Albi, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3753-8168","authenticated-orcid":false,"given":"Quoc Nghi","family":"Pham","sequence":"additional","affiliation":[{"name":"ICMMO (Institute of Molecular Chemistry and Materials), Universit\u00e9 Paris-Saclay, CNRS, 91400 Orsay, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7770-1487","authenticated-orcid":false,"given":"Doan","family":"Pham Minh","sequence":"additional","affiliation":[{"name":"Centre RAPSODEE, IMT Mines Albi, UMR CNRS 5302, Universit\u00e9 de Toulouse, Campus Jarlard, CEDEX 09, 81013 Albi, France"},{"name":"Sustainable Environment Research Institute, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,9]]},"reference":[{"key":"ref_1","unstructured":"IEA (2020).
