Features of technological synthesis and properties of ZnO-Cd based materials for photocatalytic applications. Review

In this review, the current state of ZnO-Cd based materials for photocatalytic applications is summarized. Relevant technological synthesis methods such as pulsed laser deposition, magnetron sputtering, electrodeposition, sol-gel, metalorganic chemical vapor evaporating, spray pyrolysis, reflux are considered, and recent developments in effective reproducible technology nano- microstructured zinc oxide, doped with cadmium solid solutions Zn1‑xCdxO photodecomposition organic pollutant molecules discussed. The level Cd doping has a significant effect on structure morphology oxide and, result, optical properties. figures merit, theoretical limitations rational control concentration alloying impurity necessary to create material balanced properties activity. Lastly, importance ZnO by isovalent significantly improves its due narrowing band gap, decrease rate recombination electron-hole pairs, which increases efficiency spatial charge separation, formation active radicals an increase specific surface area. Thus, most promising pollutants.
