摘要： 采用湿化学方法制备得到氧化铜纳米颗粒，进而制备氧化铜纳米流体并与石墨烯纳米流体复合得到CuO/G纳米流体。利用X射线衍射、透射电镜、紫外可见分光光谱仪等测试方法对样品进行表征。CuO/G纳米流体在太阳光波段显示出比氧化铜纳米流体和石墨烯纳米流体更加优异的光吸收性能，随着石墨烯含量的增加，CuO/G纳米流体的辐照度逐渐与太阳辐照度契合。在模拟太阳光照射下对不同质量分数的CuO/G纳米流体进行光热转换性能测试，发现随着质量分数的增加CuO/G纳米流体光热转换效率显著提高，010%的CuO/G纳米流体光热转换效率可以达到92%，体现出优异的光热转换性能。

Abstract: Copper oxide nanoparticles were prepared by a wet chemical method, and then copper oxide nanofluid was prepared and combined with the graphene nanofluid to obtain CuO/G nanofluid. The samples were characterized by Xray diffraction, transmission electron microscopy, ultravioletvisible spectrometry and other test methods. The CuO/G nanofluid exhibited superior light absorption performance in the solar spectrum in comparison to copper oxide nanofluids and graphene nanofluids. With the increase of graphene content, the irradiance of CuO/G nanofluid gradually matched the solar irradiance. The photothermal conversion performances of CuO/G nanofluids with different mass percentages were tested under the illumination of a solar simulator. It was found that the photothermal conversion efficiency of CuO/G nanofluids increased significantly with the increase of mass percentage. The thermal conversion efficiency of CuO/G nanofluid reached 92% at a mass percentage of 0.10%, showing excellent photothermal conversion performance.

Key words: copper oxide/graphene nanofluid; light absorption; photothermal conversion efficiency
