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%
