 A core-shell Pd@CeO2/γ-Al2O3 catalyst improves exhaust treatment for stoichiometric natural gas vehicles by promoting lower-temperature CH4 and NO conversion and strong hydrothermal stability. The design lowers reaction barriers at Pd-CeO2 interfaces and retains high activity after severe aging. After aging at 800 °C for 16 hours, the catalyst showed only minor losses in CH4 and NO conversion over a 100-hour test, offering a promising route to cleaner and more durable NGV aftertreatment.
