Abstract: The objective of the present study was to develop a high porosity NOx reduction catalyst using cobalt and multi-component metal from low cost transition element which was deposited onto woven stainless steel wire-mesh monolith honeycomb by sol-gel method. These metals were mixed with titanium (iv) isopropoxide as a metal oxide precursor in sol-gelphase whereby metal titanium also acts as catalyst. The reduction activity of the prepared catalyst was investigated by using Temperature Program Reduction (TPR) instrument. It was found that the synthesized catalyst has shown high porosity in which it was reflected to an amount of single point BET surface area (100.065 m2 g-1) obtained from TPR data. The morphology of the synthesized catalyst particles was analyzed by using scanning electron, microscope (SEM).
