Abstract
CdS nanoparticles (0D) were deposited using the SILAR method on the surface of titanium foil (2D), TiO2 thin films (2D) and flower-like nanostructures (NF) of TiO2 (3D). Flower-like TiO2 was gown using chemical oxidation in a 30% H2O2 solution. SEM analysis was performed to evaluate the influence of the SILAR deposition parameters and roughness of the substrate on the alignment and size of CdS. The analysis of XRD and Raman data revealed a mixture of anatase and rutile in different ratios for NF and a mixture of cubic and hexagonal polymorph for CdS. UVeviseNIR spectrophotometry showed fundamental absorption edges originating from both TiO2 (3.19e3.37 eV) and CdS (2.52e2.80 eV). The band gap energy of CdS was found to be blue-shifted. The values of photocurrentevoltage characteristics registered in a photoelectrochemical cell (PEC) were dependent by the parameters of SILAR deposition process. It was demonstrated that photoanodes based on TiO2/CdS heterostructures offer far better performance in PECs than those based on TiO2. Copyright © 2016, Hydrogen Energy Publications, LLC.
