Manganese oxide catalysts synthesized by exotemplating for the total oxidation of ethanol

Carbon Monoxide Oxidation Catalysed by Exotemplated Manganese Oxides

“…Also not much has been reported on MnO x catalysts, either pure [24][25][26][27] or with Au [9-11, 13, 14, 16-18, 20, 21] for CO oxidation. Until very recently, exotemplate materials had not been much used as catalysts, apart from our recent papers dealing with the use of these manganese oxides for ethanol oxidation [7] and exotemplated ceria oxides (with or without Au) for the oxidation of CO [28]. The work of Ren et al [6] and Zhang et al [8], dealing with metal oxides prepared using silica as template and ceria oxides synthesized using carbon nanotubes as templates, respectively, also uses the obtained catalysts for CO oxidation.…”

“…In a previous paper, our group reported on the synthesis of manganese oxides by exotemplating, using carbon materials with different textural properties and surface chemistries as templates, namely activated carbon and carbon xerogel [7]. These exotemplated materials were then used as catalysts for the oxidation of volatile organic compounds (namely ethanol) [7].…”

“…Highly porous materials have been recently synthesised by templating methods [1][2][3][4][5][6][7]. When the template has structural pores in which another solid is created and is able to provide a scaffold for the synthesis, it is called an ''exotemplate'' [3].…”

Remarkable promotion effect of trace sulfation on OMS-2 nanorod catalysts for the catalytic combustion of ethanol

“…1b, acetaldehyde is the major by-product during the ethanol oxidation process, and 100% CO 2 yield was obtained at 140°C over OMS-2-SO 4 , while it was still not fully achieved at 180°C over the OMS-2-AC catalyst. Compared with previously reported OMS-2 catalysts, the as-prepared OMS-2-SO 4 catalyst is more active than MnOx catalysts synthesized by an exotemplating method (Bastos et al, 2009) and other OMS-2 material prepared by a refluxing method , and is even superior to Pt/Al 2 O 3 catalysts (Avgouropoulos et al, 2006).…”
