Abstract

Abstract: This work presents a simple and efficient preparation of gold-plated filter membranes using thioacetamide as a pretreatment for gold colloids, and investigates the catalytic degradation of nitrophenol. The results showed that gold nanoparticles treated with thioacetamide underwent significant changes in morphology, improved stability, and increased available specific surface area, which is beneficial for enhancing their catalytic degradation activity. The catalytic performance of gold nanoparticles varies with different concentrations of thioacetamide. When the concentration is 30 μg/mL, the catalytic efficiency is highest and the catalytic time is shortest, only requiring 210 s. Cyclic service life revealed that gold nanoparticles treated with thioacetamide at a concentration of 30 μg/mL maintained 90% catalytic activity after 7 cycles of testing. This provides a feasible basis for a new type of membrane catalyst that is green, environmentally friendly, simple, and fast.
