V_2O_5/γ-Al_2O_3-TiO_2 catalysts were prepared by the mixing sol-gel and co-impregnation method. The performance of the catalysts for complete oxidation of eth
Cu/ZnO catalysts were prepared by the co-precipitation method with the addition of OP-10 (polyoxyethylene octyiphenol ether) and were chemically and structurall
