Effect of silica-to-alumina ratio on hydrocarbon adsorption–desorption properties of Ag/ZK-5 Zeolites for gasoline cold-start emission control

Cold-start hydrocarbon (HC) emissions from gasoline engines remain a critical challenge in automotive exhaust purification, as three-way catalytic converters remain inactive below their light-off temperature. Ag-modified zeolites are promising HC trap materials, yet the structure...
