In-situ preparation of a highly accessible Pt/CNF catalytic layer on metallic microchannel reactors. Application to the SELOX reaction 2015 Access copy available to the general public Unrestricted A general method to prepare a catalytic coating on the surface of stainless steel microreactors has been developed. The catalytic support consists of a layer of randomly oriented, highly accessible carbon nanofibers (CNFs), directly grown on the surface of the channels by chemical vapor deposition (CVD) of ethanol. These CNFs are functionalized to acquire a positive charge before a solution containing metallic nanoparticles (Pt) is flown through the channels. The nanoparticles adhere to the surface of the CNFs thanks to electrostatic interactions. This process is carried out in-situ and the method can be easily adapted to larger scale production. These catalyst-coated microchannel reactors have been tested in the selective oxidation (SELOX) of CO in the presence of H2. The results were compared to those obtained in a conventional fixed bed reactor packed with Pt/CNTs. The microreactor clearly outperformed the fixed bed reactor at the same space velocity (WSHV = 2220 l/h gPt),), achieving total CO conversion at temperatures 50ºC lower. info:eu-repo/grantAgreement/EC/FP7/321642/EU/Development of a microfluidic platform to produce nanomaterials and assessment on new nanotechnology applications/PLATFORM2NANO info:eu-repo/grantAgreement/ES/DGA-CAIXA/GA-LC-086-2012 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 4.012 2015 ENVIRONMENTAL SCIENCES 29 / 225 = 0.129 2015 Q1 T1 CHEMISTRY, PHYSICAL 35 / 144 = 0.243 2015 Q1 T1 1.218 2015 Process Chemistry and Technology 2015 Q1 Catalysis 2015 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-6873-5244 Sebastián, V.
