Bamboo-like MnO⋅CoO: High-performance catalysts for the oxidative removal of toluene.

The manganese-cobalt mixed oxide nanorods were fabricated using a hydrothermal method with different metal precursors (KMnO and MnSO·HO for MnO and Co(NO)⋅6HO and CoCl⋅6HO for CoO). Bamboo-like MnO⋅CoO (B-MnO⋅CoO (S)) was derived from repeated hydrothermal treatments with CoO@MnO and MnSO⋅HO, whereas CoO@MnO nanorods were derived from hydrothermal treatment with CoO nanorods and KMnO. The study shows that manganese oxide was tetragonal, while the cobalt oxide was found to be cubic in the crystalline arrangement.

Photothermal Synergistic Effect of Pt/CuO-CeO Single-Atom Catalysts Significantly Improving Toluene Removal.

Photothermal synergistic catalytic oxidation of toluene over single-atom Pt catalysts was investigated. Compared with the conventional thermocatalytic oxidation in the dark, toluene conversion and CO yield over 0.39Pt/CuO-CeO under simulated solar irradiation (λ = 320-2500 nm, optical power density = 200 mW cm) at 180 °C could be increased about 48%.

Pd/silicalite-1: An highly active catalyst for the oxidative removal of toluene.

Catalytic combustion is thought as an efficient and economic pathway to remove volatile organic compounds, and its critical issue is the development of high-performance catalytic materials. In this work, we used the in situ synthesis method to prepare the silicalite-1 (S-1)-supported Pd nanoparticles (NPs). It is found that the as-prepared catalysts displayed a hexagonal prism morphology and a surface area of 390-440 m/g.
