摘要
The ZnO nanowire/multi-walled carbon nanotube (MWNT) nanocomposites have been successfully synthesized by one-step hydrothermal method using zinc chloride as Zn source. Their photocatalytic degradation performances on methylene blue and Rhodamine 6G have been investigated under UV irradiation. Experimental results show that the photocatalytic efficiency of the as-synthesized ZnO/MWNT nanocomposites is 3 times higher than that of pure ZnO nanowires. The enhanced photocatalytic activity is attributed to the fast transfer of photo-generated electrons from ZnO to MWNTs, leading to low recombination rate of photo-induced electron hole pairs.
