ZSM-5 catalyzed one pot three-component synthesis of 5-substituted-1H-tetrazoles from aldehyde
, 2019 In this paper, we report one-pot three-component synthesis of 5-substituted-1H-tetrazoles from aldehyde using zeolite-based heterogeneous catalyst (ZSM-5). Wide functional group tolerance with high chemical yield has been achieved.

Carbon and Hydrogen, EarlyView.Dendritic micro‐mesoporous composite catalysts through K‐induced enhancement of acidity and metal dispersion were developed. ABSTRACT Novel dendritic ZSM‐22/DMSNs (ZD) micro‐mesoporous composites with center–radial pore structure and suitable acidity were developed by nano‐assembly strategy. Subsequently, Pt/ZD‐K catalysts were synthesized based on the

AIP Advances, 2017 The mesoporous Cr/ZSM-5 and W-Cr/ZSM-5 zeolites have been successfully synthesized by loading chromium and tungsten on zeolite support. The metal loaded ZSM-5 catalysts were analyzed by several characterizations such as XRD, SEM-EDS, TEM, and BET.

Carbon and Hydrogen, EarlyView.During the glycerol dehydration over ZSM‐5 zeolite, the modification by metal promoters results in the suppression of the bicyclic and tricyclic aromatics over the modified ZSM‐5 zeolite catalysts. However, the issue of the fast deactivation still remains an apparent challenge, which requires more different perspectives to understand the deactivation ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.
