The modified CNT were used as supports for 0.4\u2005wt\u2009% Ru in the direct conversion of ball\u2010milled cellulose to sorbitol and high conversions were reached after 3\u2005h at 205\u2009\u00b0C. Ru supported on the original CNT, although less active, was the most selective catalyst for the one\u2010pot process (70\u2009% sorbitol selectivity after 2\u2005h). Unlike the one\u2010pot process, the support acidity greatly promoted the rate of cellulose hydrolysis (35\u2009% increase after 2\u2005h) and the glucose selectivity (12\u2009% increase after 2\u2005h). The rate of glucose hydrogenation was almost not affected by the support modification. However, the catalyst acidity improved the sorbitol selectivity from glucose. The support acidity was a central factor for the one\u2010pot conversion of cellulose, as well as for the individual hydrolysis and hydrogenation steps, and the original CNT supported Ru catalyst was the most efficient and selective catalyst for the direct conversion of cellulose to sorbitol.<\/jats:p>","DOI":"10.1002\/cctc.201601224","type":"journal-article","created":{"date-parts":[[2016,11,21]],"date-time":"2016-11-21T12:41:44Z","timestamp":1479732104000},"page":"888-896","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Influence of the Surface Chemistry of Multiwalled Carbon Nanotubes on the Selective Conversion of Cellulose into Sorbitol"],"prefix":"10.1002","volume":"9","author":[{"given":"Luc\u00edlia S.","family":"Ribeiro","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Processos de Separa\u00e7\u00e3o e Rea\u00e7\u00e3o\u2014Laborat\u00f3rio de Cat\u00e1lise e Materiais (LSRE-LCM) Departamento de Engenharia Qu\u00edmica Faculdade de Engenharia Universidade do Porto  Rua Dr. Roberto Frias 4200-465 Porto Portugal"}]},{"given":"Juan J.","family":"Delgado","sequence":"additional","affiliation":[{"name":"Departamento de Ciencia de los Materiales e Ingenier\u00eda Metal\u00fargica y Qu\u00edmica Inorg\u00e1nica Facultad de Ciencias Universidad de C\u00e1diz  Campus Rio San Pedro 11510 Puerto Real, C\u00e1diz Spain"}]},{"given":"Jos\u00e9 J.","family":"de\u2005Melo\u2005\u00d3rf\u00e3o","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Processos de Separa\u00e7\u00e3o e Rea\u00e7\u00e3o\u2014Laborat\u00f3rio de Cat\u00e1lise e Materiais (LSRE-LCM) Departamento de Engenharia Qu\u00edmica Faculdade de Engenharia Universidade do Porto  Rua Dr. Roberto Frias 4200-465 Porto Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5447-2471","authenticated-orcid":false,"given":"M.
