摘要

•Gold supported titania catalyst for sonochemical parallel synthesis of 1,2,3-triazoles.•The effect of ultrasonics on catalyst in liquids was studied.•The Work shows synergetic effect of Au/TiO2 catalysts and the ultrasound irradiation.•SEM was used to distinguish the observed synergetic effect of fresh and spent catalysts.•HMBC 2D NMR was used as a valuable tool to unambiguously assign the obtained structures.
