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.

三维石墨烯/Cu2O纳米复合材料作为高效吸附剂和光催化

以(CH3COO)2Cu·H2O为前驱体，采用一锅无模板溶剂-热合成的方法制备了三维石墨烯(3DG)/Cu2O纳米复合材料。立方体Cu2O纳米颗粒沉积在海绵状的3DG纳米片上。吸附剂实验表明，3DG/Cu2O的吸附率为83.34%，是纯Cu2O的14倍。采用可见光下光催化降解甲基橙(MO)的方法研究了3DG/Cu2O的光催化活性。制备的3DG/Cu2O颗粒具有比Cu2O更高的光降解能力。3DG/Cu2O具有优异的MO分解活性，除了其纳米孔结构和较大的比表面积外，还与原位合成的3DG/Cu2O之间的强相互作用有关。

期刊介绍： The international Journal of Residuals Science & Technology (JRST) is a blind-refereed quarterly devoted to conscientious analysis and commentary regarding significant environmental sciences-oriented research and technical management of residuals in the environment. The journal provides a forum for scientific investigations addressing contamination within environmental media of air, water, soil, and biota and also offers studies exploring source, fate, transport, and ecological effects of environmental contamination.
