/CuO nano-heterojunction composites were prepared by sol-gel method combined electrospinning technology. X-ray diffraction and Raman spectra show that the content of CuO in the composites is increased with increasing ratios of Cu/In in the precursor solution. Absorption spectra indicate that the composite nanostructures present enhanced visible light absorption with increasing CuO content. Photocatalytic experiments show that In
