      Hi Dhow532guar84, I work mostly with heterogeneous catalysts.

      In my own case it’s all heterogeneous. Our catalysts are mostly finely divided metals, platinum, palladium or rhodium, but also iron, copper and vanadium, stuck to the surface of ceramic particles. These catalyse the oxidation of gaseous CO,hydrocarbons and ammonia or the reduction of oxides of nitrogen. There are soot particles present but these tend to get removed by filtering and burning them out, rather than being catalytically oxidised so we don’t consider that to be homogeneous catalysis. Sometimes the filters used have no catalytic content.
