Abstract: The present invention relates to a catalyzed particulate filter and methods comprising the filter for treatment of an exhaust gas from a gasoline engine, the catalyzed particulate filter comprising a gasoline particulate filter (GPF); a major catalytic layer coated onto or within an inlet side, an outlet side, or both sides of the GPF surfaces, the major catalytic layer comprising a first composition, wherein the first composition comprising a first support material; and a first platinum group metal (PGM); and a minor functional material layer placed onto or within an inlet side, an outlet side, or both sides of the GPF surfaces; the minor catalytic layer comprising a second composition; wherein the major catalytic layer has a higher loading than the minor functional material layer; the minor functional material layer is placed on top of the major catalytic layer, or the major catalytic material layer is placed on top of the minor functional layer. The catalyzed particulate filter provides an improved catalytic efficiency in conjunction with an efficient filter.
