Abstract
There-dimensional graphene (3DG)/Cu2O nanocomposites are prepared using one-pot template-free solvent-thermal synthesis route with (CH3COO)2Cu·H2O as a precursor. The cube Cu2O nanoparticles are deposited on the spongy nanosheets of 3DG. The adsorbent experiment reveals that the 3DG/Cu2O has a adsorption rate of 83.34% which is 14 times higher than that of pure Cu2O. Using photocatalytic degradation of methyl orange (MO) under visible-light illumination to investigate the photocatalytic activity of 3DG/Cu2O. The prepared 3DG/Cu2O particles exhibited a higher photo-degradation capability than Cu2O. The superior activity of 3DG/Cu2O for MO decomposition can be attributed to not only its nanoporous structure and large specific surface area, but also the strong interaction between 3DG and Cu2O from in-situ synthesis.
