| 主权项 | 1. An SCR on Diesel Particular Filter (SDPF) comprising: an exhaust gas inlet and an exhaust gas outlet; a porous filter collecting Particulate Materials (PM) of diesel exhaust gas, the porous filter having a filter pore size; a Selective Catalytic Reduction (SCR) catalyst layer coated on the exhaust gas inlet of the porous filter; an aluminum oxide layer coated on the exhaust gas outlet of the filter; and a precious metal catalyst layer coated on a surface of the aluminum oxide layer, wherein the SCR catalyst layer and the precious metal catalyst layer are separated each other by the aluminum oxide layer therebetween. | ||
