Harmony search algorithm (HS) cannot always avoid being trapped in local optima, and several local search algorithms have recently been used to overcome this limitation by searching the neighborhood of some solution for improved ones. However, how local search affects the performance of HS has...

In this work, we have prepared a series of CuO/g-C3N4 nanocomposites with CuO nanospindles anchoring on g-C3N4 nanosheets by facile ultrasonic treatment and impregnation method. The optimum 15%CuO/g-C3N4 sample exhibited higher efficiency about 9 times and 20 times compared to pure g-C3N4 for...
