Synthesis and Characterization of Cubic P-type Semiconductor Cu1.8S-deposited TiO2 Nanobelts
摘要
Abstract
TiO2 nanobelts deposited with cubic p-type semiconductor Cui.8S particles were prepared using Cu2O-deposited TiO2 nanobelts and thiourea as precursors under hydrothermal condition by Cu2O sacrificial template process. The measurement results show that the reaction temperature, reaction time and thiourea concentration have strong influence on the purity and morphology of Cu18S particles. A mixture phases of Cu18S and Cu2O on TiO2 nanobelts were obtained at 120°C for 25 h within 0.5 mol/L of thiourea concentration. While reaction temperature was raised to 160"C, the Cui.8S particles with high purity exhibited obvious aggregation, whereas the Cui 8S particles with high purity and well dispersion were prepared under 0.25 mol/L of thiourea concentration. The photocatalytic activities in degradation of Rhodamine B solution demonstrate that the Cu18S or Cu2O-loading catalysts show lower photodegradation activities as compared with that of pure TiO2 nanobelts.关键词
