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...

Here, the antibiotic levofloxacin (LFX) widely used and detected in environment was degraded by photoelectrolysis using a new electrode based on zinc oxide (ZnO) mixture of mixed oxides ruthenium titanium (MMO). The influence potential irradiation UV light investigated photostability Ti/MMO/ZnO degradation antibiotic. experiments were conducted at different pH values (5.0, 7.0 9.0) sodium sulfa...

We report the fabrication of a three dimensional branched ZnO/Si heterojunction nanowire array by a two-step, wafer-scale, low-cost, solution etching/growth method and its use as photoelectrode in a photoelectrochemical cell for high efficiency solar powered water splitting. Specifically, we demonstrate that the branched nanowire heterojunction photoelectrode offers improved light absorption, i...

Molybdenum and tungsten diselenide are among the most robust and efficient semiconductor materials for photoelectrochemistry, but they have seen limited use for integrated solar energy storage systems. Herein, we report that n-type WSe2 photoelectrodes can facilitate unassisted aqueous HI electrolysis to H2(g) and HI3(aq) when placed in contact with a platinum counter electrode and illuminated ...
