摘要

As shown in the literature, hexadecyltrimethylammonium bromide (CTAB) has been one of the most popular molecules for the preparation of Au and Ag nano-sized particles. In this work, we report a new sonoelectrochemical pathway to prepare CTAB-capped micro-sized Au sheets in solutions. After complete removal of CTAB Au nanoparticles (NPs) were released from micro-sized Au sheets in solution, in which pH was reduced simultaneously. Therefore, enriched Au NPs can be controllably obtained from micro-sized Au sheets by increasing pH of solution. Experimental results indicate the particle sizes of released Au NPs with predominant (1 1 1) face is ca. 5 nm in diameter. Moreover, the catalytic activity of the prepared Au NPs was demonstrated by analyzing the decomposition of acetaldehyde in solution.
