Preparation of metallic monolithic Pt/FeCrAl fiber catalyst by suspension spraying for VOCs combustion. Issue 27 (18th April 2018) - Li, Hao
Abstract : The catalyst was prepared by surface thermal treatment and spraying, and exhibited activity for the combustion of VOCs to CO2 and H2 O. Abstract : We report a facile and general strategy for the preparation of metallic monolithic catalysts. Our strategy involved subjecting the surfaces of FeCrAl fibers to thermal treatment and the spraying of Pt nanoparticles suspension liquid. The catalyst exhibited high catalytic activity and good stability in the combustion of volatile organic compounds to CO2 and H2 O at mild temperature. The exceptional activity of the catalyst can be attributed to the well-adhered alumina coating that formed on the surfaces of the FeCrAl fibers after thermal treatment and the highly dispersed Pt nanoparticles on the surface of the alumina coating.
