Characterization of catalytic porous medium using platinum for micro-combustion application

In this study, catalytic alumina porous medium has been fabricated by using platinum as an active material for micro-combustion application. Platinum has been deposited onto porous medium surface via wet impregnation method. The porous medium undergoes surface modification process via wash coating method using gamma alumina (γ-Al2O3) solution, before being impregnated with platinum in order to increase the surface area. The surface morphology of porous medium entirely changes from smooth "solid-rock" into rough "sand-like" after the wash coating process. The amount of platinum deposited onto the treated porous medium is 1.66 wt.. LPG combustion analysis shows that the combustion is successfully occur inside the catalytic porous media with overall efficiency of 71. © 2014 Owned by the authors, published by EDP Sciences.
