A specialized coating applied to particulate filters to chemically convert harmful exhaust pollutants into less toxic substances through catalytic reactions.
Catalytic coating is a critical component in diesel particulate filters (DPFs) and gasoline particulate filters (GPFs) that facilitates the oxidation of captured soot particles and reduces harmful emissions. This coating typically contains precious metals like platinum, palladium, or rhodium deposited on a ceramic or metallic substrate. It operates at high temperatures (typically 250-600°C) to enable continuous regeneration of the filter by converting carbonaceous particulate matter into carbon dioxide, while also reducing nitrogen oxides (NOx), carbon monoxide (CO), and unburned hydrocarbons (HC) through redox reactions.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
Catalytic coatings typically last the vehicle's lifetime (150,000+ miles) under normal conditions, but can degrade from fuel contaminants, thermal aging, or physical damage.
DOC (diesel oxidation catalyst) coatings primarily oxidize CO and HC, while DPF coatings focus on soot oxidation and may include NOx reduction functionality in SCR-coated filters.
Professional cleaning can restore some performance by removing ash deposits, but chemical degradation of the catalyst itself is irreversible.
