Catalytic oxidation performance and ion-exchange of Ti-MWW zeolite membrane with dual organic template agents and potassium carbonate

Yuan Liang et al.

Summary: In this study, tubular Ti-MWW zeolite membranes were prepared without boric acid using dual organic template agents and potassium carbonate through secondary hydrothermal synthesis. The stability of the 12MR cage and 10 MR of the MWW zeolite topology structure was achieved by TMAdaOH and HMI organic template agents, and K+ cations played a critical role as a mineralization agent in preparing the Ti-MWW zeolite membrane with a bi-layer Ti-MWW zeolites layer. Furthermore, ion-exchange significantly improved the catalytic performance of the Ti-MWW zeolite membrane for phenol hydroxylation with H2O2, and the effects of ammonium salt, ion-exchange time, and temperature on the microstructure and catalytic performance were investigated.

Reversing Titanium Oligomer Formation towards High-Efficiency and Green Synthesis of Titanium-Containing Molecular Sieves

Dong Lin et al.

Summary: The green and efficient synthesis of titanium-containing molecular sieves is hindered by environmentally unfriendly additives and complicated procedures. A new additive-free route has been developed using hydroxyl free radicals generated from ultraviolet irradiation, successfully reversing the formation of titanium oligomers to match hydrolysis rates of titanium and silicon species. This approach shows fantastic catalytic performance for propene epoxidation with H-2 and O-2, opening up new opportunities for high-efficiency, environmentally friendly, and facile production of pure titanium-containing molecular sieves compared to conventional hydrothermal methods.
