Electro-induced hydrophilicity of hydrogen plasma bombarded Ag/TiO2 nanostructure

Electro-induced hydrophilicity of the Ag/TiO2 nanostructure has been reported in this study. In this work hydrogen plasma bombarded Ag/TiO2 nanostructure was created using a sequential process including chemical vapor deposition and plasma bombardment. X-ray diffraction and X-ray photoelectron spectroscopy were used to analyze structure and chemical states of the sample. The prepared Ag/TiO2 heterostructure has enhanced visible-light-induced hydrophilicity comparing to pure TiO2. The electro-induced hydrophilicity of the samples was also examined by creating the comb like electrodes on the prepared Ag/TiO2. A super-hydrophilic surface was achieved by applying an electric bias voltage on the electrodes.
