Transparent Porous ZnO|Metal Complex Nanostructured Materials: Application to Electrocatalytic CO2 Reduction

“…32 However, the catalytic system suffered from degradation issues due to morphological changes during CO 2 reduction in aqueous media. ZnO has the distinct advantage of being easily prepared in high quality and in a wide range of nanostructures, such as nanorods, 33,34 nanotubes, 35,36 and nanobelts, 37,38 via solution routes such as chemical bath deposition (CBD)/dip coating, 39 chemical vapor deposition (CVD)/spray pyrolysis, 40 hydrothermal synthesis, 41 and electrochemical deposition. 42,43 Electrodeposition is a low-temperature (mostly <100 °C) cost-effective deposition process that allows the design of complex ZnO nanostructures by combining and adjusting the growth conditions.…”

The loading of organic molecules into ZnO films was also attempted using a ZnCl 2 bath employing cathodic reduction of the dissolved molecular oxygen precursor. ,, In the present study, electrodeposited ZnO layers will be used as a matrix for the incorporation of molecular catalysts.…”

Comparative Study on the Effects of O2 Flow Rate on As-Deposited Polycrystalline IAZO Films

“…This phenomenon supports the highest deposition rate and thickness in SD films. Due to the very low O 2 concentration in the vacuum chamber, there is minimal reaction between the metal plasma and O 2 , allowing atomic Zn to adsorb on the substrate without reacting with O 2 . This abnormally increases the deposition rate.…”

“…Due to the very low O 2 concentration in the vacuum chamber, there is minimal reaction between the metal plasma and O 2 , allowing atomic Zn to adsorb on the substrate without reacting with O 2 . 21 This abnormally increases the deposition rate. The diffraction patterns indicated that the as-deposited films were polycrystalline in nature.…”

Facile low temperature processed nanostructure ZnO QD based thin films for potential perovskite solar cell: thickness dependence of crystal and electrical properties.

“…Electrodeposition, chemical vapor deposition, magnetron sputtering, hydrothermal, precipitationspin coating and spray pyrolysis methods were utilized to prepare ZnO thin films [7][8][9][10][11]. However, the precipitation-spin coating technique has the merits of being a non vacuum, inexpensive, and simple with low-temperature processing and compositional control.…”
