Year: 2025
Type: article
Abstract: Photocatalytic decontamination has emerged as a highly promising technology for air pollutant control and energy conversion. In this work, a semiconductor photocatalyst was synthesized via a hydrothermal method, featuring nano-sized TiO 2 doped with nickel (Ni), zirconium (Zr), and nonmetallic nitrogen (N). The kinetic process of synchronous abatement of the SO 2 -NO x binary gas system was systematically investigated in a self-designed photocatalytic reactor. From the perspective of quantum optics, a light quantum efficiency model was established to elaborate the photocatalytic degradation mechanism, accompanied by a detailed analysis of the synergistic effects of multiple influencing factors on the interaction between incident light and pollutants. Experimental results revealed that flue gas concentrations exert significant impacts on contaminant removal efficiencies. Notably, the experimental data showed excellent consistency with the calculated results across a wide range of operational conditions.
