“…In contrast, the noble metal-supported catalysts are widely used in view of their good catalytic activity and high durability despite their relatively expensive. , Toluene, as a typical organic solvent, is extensively used in the manufacturing industry. However, its high volatility can lead to the generation of excessive hazardous organic gases in the workplace, which poses significant risks to workers’ color vision, hearing, and central nervous system, potentially causing occupational diseases. For decades, Pt/CeO 2 has been widely employed in the toluene catalytic oxidation fields.…”

In this research, a range of Pt/CeO 2 catalysts featuring varying Pt−O−Ce bond contents were developed by modulating the oxygen vacancies of the CeO 2 support for toluene abatement. The Pt/CeO 2 −HA catalyst generated a maximum quantity of Pt−O−Ce bonds (possessed the strongest metal− support interaction), as evidenced by the visible Raman results, which demonstrated outstanding toluene catalytic performance. Additionally, the UV Raman results revealed that the strong metal− support interaction stimulated a substantial increase in oxygen vacancies, which could facilitate the activation of gaseous oxygen to generate abundant reactive oxygen species accumulated on the Pt/ CeO 2 −HA catalyst surface, a conclusion supported by the H 2 -TPR, XPS, and toluene-TPSR results. Furthermore, the results from quasi-in situ XPS, in situ DRIFTS, and DFT indicated that the Pt/ CeO 2 −HA catalyst with a strong metal−support interaction led to improved mobility of reactive oxygen species and lower oxygen activation energies, which could transfer a large number of activated reactive oxygen species to the reaction interface to participate in the toluene oxidation, resulting in the relatively superior catalytic performance. The approach of tuning the metal−support interaction of catalysts offers a promising avenue to develop highly active catalysts for toluene degradation.

Objective. The aim is to explore the effect and mechanism of indoor toluene exposure on orienting network. Methods. Twenty-two healthy adults were exposed to 0 ppb, 17.5 ppb, 35 ppb, and 70 ppb toluene for 4 hours, respectively. All subjects underwent attention network behavioral test, and their electroencephalographic activity was recorded simultaneously. The causal connection strengths of orienting network were calculated through direct transform function (DTF) methods. The DTF values of orienting networks among four groups were compared. Results. (1) The DTF values of parietal outflow (DTF_outflow) in 70 ppb toluene condition were higher than those of the 0 ppb, 17.5 ppb, and 35 ppb conditions, respectively. (2) The DTFCZ-FZ and DTFCZ-FP2 values of 70 ppb toluene condition were found to be lower as compared to 0 ppb condition. The DTFCZ-FP2 values of 70 ppb condition were lower as compared to those of the 17.5 ppb condition. Furthermore, DTFP3-FP2, DTFP4-FP1, and DTFP4-FZ values of 70 ppb condition were higher as compared to those of the 0 ppb condition. The DTFP3-FP2 values of 70 ppb condition were higher as compared to those of the 17.5 ppb condition. The DTFP4-FP1 values of the 70 ppb condition were higher as compared to those of the 17.5 and 35 ppb conditions. Conclusion. Even short-term exposure to indoor toluene at low concentrations significantly impacts orienting network.
