A non-surfactant route synthesized mesoporous AlTUD-1 (Si/Al = 25) with interconnected porous networks effectively utilized as a support for 10 wt% tungsten oxide (WO 3 ) dispersions. The synthesized WO 3 /AlTUD-1 catalyst was characterized by different techniques. N 2 sorption and XRD studies were confirmed its amorphous mesoporous nature, which measured a pore diameter of 6.4 nm and a surface area of 510 m 2 g −1 . Presence of WO 3 on the pores and silica TUD-1 wormhole structure were

... d by techniques including DRUV Visible and FT-Raman. The catalyst possessed both Lewis (L) and Brønsted (B) acidity, as measured by pyridine adsorbed FT-IR, which is responsible for the catalyst activity. WO 3 /AlTUD-1 acid catalyst showed an excellent catalytic performance yield of about 80% at 80 °C in reflux condition, for different 1-substituted benzylidene 4-methylbenzo[d]thizole-2-amines (thiazole based aryl imines) and substituted phenylhydrazone compounds.
