Ultrasound-assisted synthesis of NaZn2(OH)(MoO4)2·H2O for effective sonocatalytic performance

Abstract

Herein, Sodium Zinc Hydroxide Molybdenum (NaZn2(OH)(MoO4)2·H2O) micro-nano material by applied in the sonocatalytic degradation of methyl orange (MO) was synthesized by a simple one-step sonochemistry method. The pH value of the reaction solution, the ultrasonic time of synthesis and the ultrasonic power have a certain influence on the morphology, size and sonocatalytic performance of the NaZn2(OH)(MoO4)2·H2O micro-nano material, at the same time, the possible growth mechanism of the material synthesized under ultrasonic radiation conditions was proposed. The as-prepared sonocatalyst exhibited superior sonocatalytic efficiency for MO under ultrasonic irradiation. In addition, the sonocatalytic degradation activity of NaZn2(OH)(MoO4)2·H2O was optimized. Finally, we proposed a possible mechanism of ultrasonic catalytic degradation by according to free radical capture experiment.
