Optimizing Height and Packing Density of Oriented One-Dimensional Photocatalysts for Efficient Water Photoelectrolysis

Dependences of water-photoelectrolysis efficiency on heights and packing densities of vertically arrayed ZnO nanorods (NRs) and ZnO microrods (MRs) were systematically studied for the first time over a wide range of light incidence angles, under the direction of nanooptics simulation. In the photoelectrolysis, dense NRs of 1.8 μm in height afforded the highest photocatalytic efficiencies, and f...

One‐dimensional TiO2 Nanotube Photocatalysts for Solar Water Splitting

Hydrogen production from water splitting by photo/photoelectron-catalytic process is a promising route to solve both fossil fuel depletion and environmental pollution at the same time. Titanium dioxide (TiO2) nanotubes have attracted much interest due to their large specific surface area and highly ordered structure, which has led to promising potential applications in photocatalytic degradatio...

Maximizing One-Dimensional Porous Emitter Packing Density for Electrospray Applications

The emitted current as a function of applied voltage has been investigated for linear electrospray emitter arrays of different emitter separation distances. The emitter arrays were fabricated out of porous tungsten using conventional micro fabrication techniques adapted for use on porous substrates. Experimental results are provided for samples of each emitter density and show that the emitter ...

Water Splitting: One‐dimensional TiO2 Nanotube Photocatalysts for Solar Water Splitting (Adv. Sci. 1/2017)

One-step synthesis of highly efficient three-dimensional Cd1-xZnxS photocatalysts for visible light photocatalytic water splitting

Visible light accounts for about 43% of the solar spectrum, and developing highly efficient visible-light-driven photocatalyst is of special significance. In this work, highly efficient three-dimensional (3D) Cd1-xZnxS photocatalysts for hydrogen generation under the irradiation of visible light were synthesized via one-step solvothermal pathway. Scanning electron microscope, X-ray diffractomet...
