Novel method for insertion of Pt/CeZrO2 nanoparticles into mesoporous SBA-16 using hydrothermal treatment

Efficient production of dihydroxyacetone from glycerol over a Pt/CeO2-ZrO2-Bi2O3/SBA-16 catalyst

“…SBA-16 (SBA) was synthesized according to the method in the previous study [27]. Pluronic F-127 (1.6 g) and 1,3,5-trimethylbenzene (1.1 mL) were dissolved into 0.2 mol• L −1 hydrochloric acid (90 mL).…”

Catalytic liquid phase oxidation of 1,4-dioxane over a Pt/CeO2-ZrO2-Bi2O3/SBA-16 catalyst

“…1 Catalyst preparation SBA-16 was prepared according to the hydrothermal method described in previous studies [10,14]. Pluronic F-127 (1.6 g) and 1,3,5-trimethylbenzene (1.1 cm 3 ) were dissolved into 0.2 mol/dm 3 hydrochloric acid (90 cm 3 ), and the mixture was stirred at 35 ℃ for 3 h. After stirring, tetraethyl orthosilicate (7.1 cm 3 ) was added to the solution, and the mixture was stirred again at 35 ℃ for 20 h. Then the mixture was poured into a Teflon bottle in a sealed brass vessel and heated at 140 ℃ for 24 h. The solid product was collected by filtration, washed and dried at room temperature for 12 h. Finally, the dried powder was calcined at 600 ℃ for 4 h in air to obtain SBA- 16 3 ) was added, and the mixture was stirred at room temperature for 6 h. The content of Ce 0.68 Zr 0.17 Bi 0.15 O 1.925 was adjusted to be 16 wt%, which was the optimum amount for toluene oxidation [15].…”

Selective oxidation of glycerol to dihydroxyacetone using CeO2-ZrO2-Bi2O3-SnO2-supported platinum catalysts

“…SBA-16 was prepared via a hydrothermal reaction similar to that in the previous study [19]. Pluronic F-127 (1.6 g) and 1,3,5-trimethylbenzene (1.1 mL) were dissolved in 0.2 mol•L −1 hydrochloric acid (90 mL), to which tetramethyl orthosilicate (7.1 mL) was then added.…”
