文摘

3D-3D porous Bi2WO6/graphene hydrogel (BWO/GH) composite was synthesized by a facile one-step hydrothermal method. It achieves the homogeneous dispersion of the 3D flower-like BWO in GH by controlling the growth of BWO precursors. 3D-structured BWO/GH composite realized the synergistic effect of adsorption and photocatalysis. The 3D multilevel structure of BWO/GH composite highly improves the utilization rate of light. It shows new insights for the development of BWO/GH photocatalyst and application of water purification in dynamic system.
