Self-assembled aligned Cu doped ZnO nanoparticles for photocatalytic hydrogen production under visible light irradiation

Co-Precipitation Synthesis and Characterization of Nanocrystalline Zinc Oxide Particles Doped with Cu<sup>2+</sup> Ions

“…It is known that [25,26]. The inherent reason for red shift in band edge in transition metal doped ZnO samples is due to the change of the sp-d exchange interaction between the band electrons and the localized d-electron of the Cu 2+ ions [27].…”

Optical spectroscopy characterization of Cu doped ZnO nano- and microstructures grown by vapor-solid method

“…Some other dopants have been used to modify a variety of material properties, for instance, elements of group III such as In, Ga, Al have been introduced to increase the density of carriers (electrons) and change the luminescent properties [7,8,9]. In the case of Cu, some studies have been done to investigate its positive influence on photocatalytic processes, as well as its utility for making CO sensors [10,11,12]. For these applications, it is important to know the distribution and location of the Cu atoms through the host material [10] as well as its influence on the electronic and optical properties.…”

Generation of Useful Hydrocarbons and Hydrogen during Photocatalytic Decomposition of Acetic Acid on CuO/Rutile Photocatalysts

“…The photocatalytic evolution of hydrogen in the presence of sacrificial agents has been already described in the literature [18,[20][21][22][26][27][28][29][30][31][32][33][34]. In general, when the reducing agent, or hole scavenger, such as alcohol [20,23,[26][27][28][29], organic acid [18,30,31] or sulfide ion [32,33], is present in the solution, the photogenerated holes react with the reducing agent. As a result the photocatalyst is enriched with electrons and H 2 evolution reaction is enhanced [34]:…”
