The rapid elimination of volatile organic compounds and the intermediate analysis with efficient photothermal catalysis are great significance to environment. Oxygen vacancies (Vo) play a crucial role in structural modification performance improvement heterogeneous catalysts. Accordingly, here, abundant Vo sites introduced into Co3O4/TiO2 composite via treatment under H2 Ar flow at 200°C, catalytic toluene is significantly improved. molecular oxygen (O2) adsorbed by activated form reactive species for deep oxidation toluene. generated on unilateral side heterojunctions serves capture electrons break dynamic balance electron-hole pairs. excited trapped Vo, direct recombination pairs inhibited, thus promoting photochemical process. Moreover, synergy effect relationship between evolution intermediates transformation mechanism systematically studied.

Electron Beam Irradiation-Induced Defects Enhance Pt-TiO2 Photothermal Catalytic Degradation in PAEs: A Performance and Mechanism Study

Molecules, Год журнала: 2025, Номер 30(3), С. 697 - 697

Phthalic acid esters (PAEs), ubiquitous semi-volatile organic compounds (SVOCs) in indoor environments, pose adverse effects on human health. However, their degradation mechanisms and pathways remain unclear. Herein, we developed an efficient photothermal catalyst by introducing defects (oxygen vacancies, OVs) TiO2 (P25) surfaces via electron beam irradiation technology with different doses (100, 300, 500, 700 kGy). The was employed as a support to prepare Pt-TiO2 catalysts for the of di (2-ethylhexyl) phthalate (DEMP) dimethyl (DMP), two representative PAEs. pre-treated 300 kGy dose supported Pt (Pt-Ti-P-300) presented optimal catalytic performance DEMP DMP degradation. Characterization results confirmed that OVs were successfully introduced catalysts. Meanwhile, induced expanded light absorption range improved generation separation photogenerated carriers, which significantly enhanced activity PAE Importantly, mechanism pathway further explored using situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) gas chromatography–mass spectrometry (GC-MS). These findings provide important insights into irradiation-mediated regulation removal PAEs environments.
