“…Wenfang Wang and co-workers [16] prepared and studied the micro-structure and properties of Cu/TiO 2 composite coating. Jun Yan and other authors [17] found that the light absorption threshold of the sample had a redshift from 397.5nm to 448.9nm after preparing TiO 2 on the surface of Cu, which can be attributed to a new energy level appearing below the conduction band after supporting of Cu, resulting in the narrow band gap and red-shift absorption. However, it should be noted that in ref 17 butyl titanate was chosen as raw material for the preparing of TiO 2 on the surface of Cu.…”

Cu-supported nano-TiO2 catalyst was prepared by forced hydrolysis method under mild condition. The morphology, composition and optical absorption properties of the samples were characterized by means of scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and UV-Vis diffuse reflectance spectroscopy (UV-VIS DRS). Visible photocatalytic activity of the samples was investigated by photocatalytic degradation experiment on methyl orange. The results indicated that nano-TiO2 was about 20nm in size with the main form of anatase, and photo response range was significantly broadened after it was loaded on the surface of Cu. The sample possessed high visible light catalytic activity, with the degradation rate of methyl orange reaching 94% under simulated natural light.

Nano-TiO2/Micron size Cu composite particles were prepared in ambient conditions by bio-inspired method. Observation by field emission scanning electronic microscope shows TiO2 particles of 3-5 nm covers on copper powder surfaces to form nanometer/micron composite particles. XPS analysis shows that the element C, O, Ti, Sn and Cu existed on the surfaces of the composite particles. UV-vis spectra show a red shift of the absorption edge and a significant increase of absorption intensity in the visible region. The degradation experiment taking methyl orange demonstrates the photocatalysis activation of powder with good body made. At the same time, the apparent kinetics model for degradation reaction was established.
