An apparatus for removing soot from diesel engine exhaust streams at temperatures below 150&#xb0; C. is provided. Although the use of particulate filters for removing carbonaceous soot from such exhaust streams is known, such systems are either active or operate under high temperatures, i.e. in excess of 300&#xb0; C. The claimed apparatus includes a flow through support device composed of ceramic, such as cordierite or silicon carbide, or a primarily nonferrous metal or stainless steel and coated with an oxide formation comprising hematite and bixbyite in a ratio from 1:1 to 9:1. The claimed apparatus can also include a diesel particulate filter coated with a coating comprising tin, aluminum and zirconium oxides prepared by a co-precipitation process and thereafter coated with platinum or other precious metal.
