Regulating catalytic stability of PtSnM/CeO2 (M = Mn, W, Nb) catalysts via the closely coupled multi-active sites to promote multicomponent VOCs oxidation

Pt anchored in the skeleton of rice husk-based ZSM-5 for excellent catalytic VOC oxidation: structure–activity relationship and environmental impact assessment

“…7a, the signals ( m / z = 92) are attributed to the desorption of the weakly and strongly chemisorbed C 7 H 8 species at 70–200 and 258 °C, respectively. 46 In addition, Pt/ZSM-5-T2 demonstrates the largest desorption peak of C 7 H 8 , indicating that Pt/ZSM-5-T2 has the highest C 7 H 8 adsorption capacity. In the meantime, the CO 2 desorption curve also proves that a significant amount of C 7 H 8 was adsorbed on the Pt/ZSM-5 catalysts (Fig.…”

Enhanced catalytic oxidation of toluene over amorphous cubic structured manganese oxide-based catalysts promoted by functionally designed Co–Fe nanowires

“…, noble metal-based catalysts ( e.g. , Pt, Pd, and Au based ones) 11–13 and transition metal-based catalysts ( e.g. , Mn, Co, Ni, and Fe based ones) 14–16 have been widely designed and applied for VOC removal.…”

Study on the Catalytic Oxidation of Toluene Using CeO2@S-AZMB Prepared from Spent Zn-Mn Batteries

“…Metal oxide catalysts are widely used because of their stable catalytic activity, high thermal stability, high availability, and low price [1][2][3][4]. A large number of studies have shown that both MnOx and CeO 2 have high thermal catalytic activity, and the combination of MnOx and CeO 2 can form a Mn-Ce composite catalyst with higher activity [5][6][7][8]. In recent years, Mn-Ce composite catalysts have attracted extensive attention from researchers due to their high catalytic activity, and a large number of studies have been carried out on the disadvantages of Mn-Ce catalyst particles such as their easy agglomeration and uncontrollable morphology.…”
