Modifications of graphitic C3N4 with multi-metal oxides for enhanced visible-light active photocatalysis

Masih D., Rohani S., University of Western Ontario, CA
Bulk graphitic C3N4 (g-C3N4) is a p-type semiconductor with band gap of 2.7 eV. For photocatalytic water splitting, valance and conduction band gap positions of g-C3N4 sandwich both oxygen and hydrogen evolution potentials, making g-C3N4 [...]

Deposition of TiO2/Ni/CuO/ITO multi-layered cell for solar-driven water splitting

Wu K.R., National Kaohsiung Marine University, TW
In this study, a photoelectrolysis cell based on multilayered TiO2/Ni/CuO (M-cell) photoelectrode is prepared on ITO substrate (110 nm thick) using a multi-target direct current and radio-frequency magnetron sputtering technique in which Ni acts as [...]

Catalytic activities of sputtered p-type Cu2O electrode in connection with TiO2 thin film for dye degradation

Hsu C.J., Hung C.H., Sun J.C., Wu K.R., Yeh C.W., National Kaohsiung Marine University, TW
In this study, a p/n-type photoelectrocatalytic (PEC) cell was used to enhance the photocatalytic (PC) and PEC activities towards the degradation of methylene blue (MB) solution under ultraviolet (UV) irradiation. The PEC cell consists of [...]

Electroluminescence of ZnO Nanowire/p-GaN Heterojunction Light Emitting Diodes

Cole J.J., Jacobs H.O., Wang X., University of Minnesota, US
ZnO nanowire/p-GaN heterojunction light emitting diodes (LEDs) were fabricated by growing ZnO nanowire vertical arrays in aqueous solution on Mg-doped p-GaN films. Diode-like, rectifying I-V characteristics were recorded at room temperature and a “current crowding” [...]
