Comparing with Ceramic Honeycomb Substrate, Metal Honeycomb Substrate has the advantages of fast burning, small volume, high mechanical strength, prominent heat-resistance, etc. This hot sale item is widely used in exhaust gas purification equipment, especially car, motorbike etc. It should be pretreated to generate a transition layer which is to solve the mismatched heat expansion between metal honeycomb substrate itself and the active layer. On the transition layer, it is coated with the rare earth catalyst layer, while in active layer is coated with noble metal like Pt, Pd, Rh.

For light duty petrol vehicls exhaust purification, through the precious metals and earth catalyst, the exhaust HC, CO and NOx and other harmful components into harmful N2, CO2 and H2O in order to reach EuroII to EuroIV emission standards. As you know a catalyst contains noble metal (Pt, Pd, Rh) with rare earth.
