Photocatalytic water splitting over titania supported copper and nickel oxide in photoelectrochemical cell; Optimization of photoconversion efficiency

We investigated the influence of fluctuating the preparation variables of TiO2 on the efficiency of photocatalytic water splitting in photoelectrochemical (PEC) cell. Hydrothermal associated sol-gel technique was applied to synthesis modified TiO2 with nickel and copper oxide. The variation of water...
