In this paper, hierarchical ZnO flowers are assisted the combustion during annealing, leading synthesized via a hydrothermal method. Sucrose as a fuel to the improvement of the microstructure of samples. ZnO flowers are characterized by XRD and SEM. Photocatalytic activity is evaluated using the degradation of organic dye methyl orange. The sucrose added ZnO flowers show improved activity, which is mainly attributed to the better crystallinity as confirmed by XRD analysis. The effect of sucrose amount on photocatalytic activity is also studied.
