Most of the reported catalysts are based on Cu\/ZnO supported in inorganic oxides, with not much progress with respect to the benchmark Cu\/ZnO\/Al2O3 catalyst. The use of carbon supports for Cu\/ZnO particles is much less explored in spite of the favorable strong metal support interaction that these doped carbons can establish. This manuscript reports the preparation of a series of Cu-ZnO@(N)C samples consisting of Cu\/ZnO particles embedded within a N-doped graphitic carbon with a wide range of Cu\/Zn atomic ratio. The preparation procedure relies on the transformation of chitosan, a biomass waste, into N-doped graphitic carbon by pyrolysis, which establishes a strong interaction with Cu nanoparticles (NPs) formed simultaneously by Cu2+ salt reduction during the graphitization. Zn2+ ions are subsequently added to the Cu\u2013graphene material by impregnation. All the Cu\/ZnO@(N)C samples promote methanol formation in the CO2 hydrogenation at temperatures from 200 to 300 \u00b0C, with the temperature increasing CO2 conversion and decreasing methanol selectivity. The best performing Cu-ZnO@(N)C sample achieves at 300 \u00b0C a CO2 conversion of 23% and a methanol selectivity of 21% that is among the highest reported, particularly for a carbon-based support. DFT calculations indicate the role of pyridinic N doping atoms stabilizing the Cu\/ZnO NPs and supporting the formate pathway as the most likely reaction mechanism.<\/jats:p>","DOI":"10.3390\/nano14050476","type":"journal-article","created":{"date-parts":[[2024,3,6]],"date-time":"2024-03-06T04:03:50Z","timestamp":1709697830000},"page":"476","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Nanometric Cu-ZnO Particles Supported on N-Doped Graphitic Carbon as Catalysts for the Selective CO2 Hydrogenation to Methanol"],"prefix":"10.3390","volume":"14","author":[{"given":"Lu","family":"Peng","sequence":"first","affiliation":[{"name":"Instituto de Tecnolog\u00eda Qu\u00edmica, Consejo Superior de Investigaciones Cient\u00edficas-Universitat Politecnica de Valencia, Av.
