High aspect ZnO nanorod growth over electrodeposited tubes for photocatalytic degradation of EtBr dye

Abstract

In this work, vertically grown rod type ZnO nanostructures have been synthesized on metallic nickel tube films fabricated through the cost-effective process of electroforming..

A review on bismuth oxyhalide based materials for photocatalysis

“…[178][179][180][181][182][183][184][185][186] Wide bandgap energy (3.2 eV) of ZnO restricts its photocatalytic performance to UV irradiation only. [187][188][189][190][191] To enhance photocatalytic performance and its ability to absorb sunlight, different photocatalyst composites (ZnO/BiOX) have been synthesized. 155,[192][193][194] Geng et al prepared various BiOBr/ZnO materials through hydrothermal method of methylene blue (MB) removal in its aqueous phase.…”

Gas Sensor Applications in Water Quality Monitoring and Maintenance

“…A vast amount of work based on the metal oxide gas sensor has been performed by various researchers viz., Biswal et al developed ZnO nanorods and investigated their utility to degrade ethylene bromide dye from wastewater [30]. An e-nose composed of 12 sensors of metal oxidization has been used in a domestic wastewater treatment plant effluent to track the volatile compounds [31,32].…”

Development of dual-functional catalysis for hydrazine oxidation by an organic p–n bilayer through in situ formation of a silver co-catalyst

“…In addition to the application in uphill reactions with DG > 0 (e.g., water splitting), [1][2][3][4][5] photocatalysts are also effectively applied in downhill reactions with DG < 0 (e.g., decomposition of pollutants), particularly when kinetically severe oxidation with large activation energy is involved. [6][7][8][9][10] Among the photocatalysts, TiO 2 is recognized to be practically used in the degradation of several types of pollutant. [11][12][13][14][15] However, the degrading targets are limited to only substances of low concentrations because of the ultraviolet (UV) response of TiO 2 .…”
