- With the stringent China6 legislation implementation in 2020, Gasoline Particular Filters (GPF) are widely applied to control Particle Number (PN), THC, CO, and NOx emissions from gasoline engines. The typical GPF product in the market is usually coated with a Pd/Rh three-way catalyst (TWC). In this work, a novel and cost-effective GPF was achieved through Pd substitution with lower cost Pt in a novel Pt/Rh TWC coating. The Pt/Rh GPF was evaluated for back pressure (BP) under clean and soot loaded conditions, PN Filtration efficiency, TWC activity, and soot regeneration. The aged Pt/Rh GPF gave superior TWC performance.
