Abstract
En 中文
With the acceleration of industrialization and the increase in car ownership; exhaust pollution has become a major global environmental challenge. Harmful gases such as carbon monoxide (CO) and nitrogen oxides (NOx) are discharged into the air; forming acid rain; producing chemical smog; and destroying the ozone layer. This causes severe harm to the environment and human health. Rh-based catalysts play a crucial role in exhaust gas treatment due to their excellent performance in selective catalytic reduction (SCR) and direct nitrogen oxide decomposition (DND) of NOx. However; deactivation limits their stability and service life; increasing costs and restricting industrial application. This paper reviews the reaction mechanisms of Rh-based catalysts in SCR and DND reactions; discusses deactivation mechanisms; and proposes improvement strategies. It provides theoretical basis and practical guidance for the development of efficient and stable catalysts for exhaust gas treatment.
