非晶态YBO结构与甲苯催化燃烧性能研究

oluene, as a typical volatile organic compound (VOCs), poses health risks such as cardiovascular diseases through atmospheric diffusion. The efficient degradation of toluene via catalytic combustion technology has attracted significant research attention. A series of amorphous YBO catalysts were synthesized by adjusting phase formation temperature through the sol-gel method. The amorphous characteristics were characterized using XRD, TEM, and FT-IR techniques, and their performance in catalytic toluene combustion was evaluated. Results demonstrate that the surface oxygen defects and three-coordinated boron centers in YBO-1 configuration serve as active sites, achieving complete conversion of toluene to CO2 and H2O at 350 C. Further loading with noble metal Pd reduced the T90 temperature to 226 C. This study elucidates the fundamental structural units and catalytic mechanisms of amorphous YBO materials, providing both theoretical foundations and practical references for developing novel catalytic combustion materials for VOCs treatment.
