Abstract Heterogeneous Fenton method stands out due to its simplicity, rapid reaction rates, low costs, and high degradation efficiency, making it an ideal candidate for NO oxidation removal in low‐temperature flue gas. The catalyst plays a crucial role determining the catalytic efficiency of heterogeneous reaction. Biochar, characterized by rich pore structure, abundant surface functional groups, adsorption strength, serves as excellent carrier catalysts. This paper investigates impact various factors on using biochar loaded with nano Fe 3 O 4 catalyst. study identifies optimal process conditions improvement mechanism reducing modification is also analyzed depth. Results indicate that increases higher concentrations injection rates H 2 . temperature range atomization zone found be between 150 170°C. Increasing iron content significantly enhances approximately 50%. controlled adjusting pH synthesis solution, increasing from 7 13 raises 84.1% 99.1%. Quantum chemical calculations further demonstrate levels correlate greater degrees reduction, increased number CC sp hybrids, enhanced electron transfer all which contribute improved efficiency.

ABSTRACT Pollutant emissions such as carbon monoxide (CO), hydrocarbons (HCs), nitrogen oxides (NO x ), and particulate matter (PM) from diesel engines have serious adverse effects on both human health the environment. Advanced post‐engine emission control systems, oxidation catalyst (DOC) selective catalytic reduction (SCR), proven effective in substantially reducing or minimizing of CO, HC, NO . Additionally, use metal‐based fuel additives has been widely studied applied practice to improve engine performance optimize outcomes. The interaction between DOC SCR systems become a key area research focus. This study investigates impact additives—including cerium (IV) oxide, copper (II) magnesium nickel titanium oxide—on catalysts under various load conditions. In experiments, conventional were used, specifically Pt/Al 2 O 3 for V 5 ‐WO /TiO versus Ag/Al SCR. variations NO, levels exhaust gas monitored, efficiency converting these was calculated analyzed. results indicate that combination with technologies can effectively reduce pollutant engines. Among tested, oxide found be particularly enhancing conversion efficiencies systems.
