Abstract:

A method for synthesizing a CdS/TiO2 composite material, active in the visible region, was described. The CdS/TiO2 composite was obtained by the sol-gel synthesis of nanostructured TiO2 in a medium of a stable colloidal solution of CdS nanoparticles. The TiO2 matrix produced by the sol-gel process is amorphous and contains a nanocrystalline anatase phase, the content of which depends on the Ti(OBu)(4) hydrolysis rate. The content of CdS nanoparticles forming in the colloidal solution and participating in the TiO2 matrix sensitization is determined by the initial CdS: Ti(OBu)(4) ratio. Although the content of CdS nanoparticles in the composite is low (no more than 3 wt \%), the composite demonstrates catalytic activity in the visible region, thus proving the possibility of reducing the content of toxic CdS nanoparticles in the TiO2 matrix without decreasing the photosensitivity of the CdS/TiO2 composite.
