Effect of Pd/Ce loading on the performance of Pd–Ce/γ-Al2O3 catalysts for toluene abatement

Recent progresses in the synthesis of MnO2 nanowire and its application in environmental catalysis

“…Toluene could directly threaten the human and safety because of its carcinogenicity and teratogenicity. 150,151 Therefore, the effective removal method of toluene should be explored in great urgency considering the harmful effects of toluene on the human health and the strict environmental regulations. Cheng et al 83 found that a-MnO 2 nanowires performed much higher catalytic activity than the commercial MnO 2 counterpart toward toluene combustion.…”

Highly Active PdO/Mn3O4/CeO2 Nanocomposites Supported on One Dimensional Halloysite Nanotubes for Photoassisted Thermal Catalytic Methane Combustion

“…The former is responsible for boosting synergistic effects among components to accelerate O spillover, and the latter helps produce more Ce 3+ to continuously activate O 2 via chemical adsorption into O*. [23] CH 4 -TPR results (Figure 3 c) further disclose that under irradiation only PdO-containing samples showed stronger adsorption (uptrend) as well as The electron paramagnetic resonance (EPR) signals with a g factor of 2.003 should be attributed to Ce 3+ (Figure 3 d,e). It can be seen that the intensity of the Ce 3+ signals increased significantly under irradiation or by increasing temperature, also suggesting the presence of a higher concentration of oxygen vacancies.…”

Advances in Catalytic Oxidation of Volatile Organic Compounds over Pd-Supported Catalysts: Recent Trends and Challenges

“…Pd 0.01 Mn 0.2 /Ti catalyst exhibited superior catalytic performance for acetone oxidation than its counterpart catalyst in the absence of Mn due to the presence of high valence states of Mn in the catalyst (Zhao Q. et al, 2019). The bimetallic Pd-Ce/γ-Al 2 O 3 catalyst displayed better catalytic performance than Pd/γ-Al 2 O 3 , further indicating that Ce loading improved the catalytic activity by reducing the amount of precious metals incorporated within the catalyst (Ren et al, 2020). The high water-resistant ability of the supported Pd−W bimetallic catalysts was ascribed to the presence of the facile redox cycle of the active Pd 2+ /Pd 0 couple (Liang et al, 2019).…”
