“…30 It is reported that the addition of Ag enhances the photocatalytic activity of ZnO as much as 34% because of excited electrons sequestration by Ag nanoparticles, which prevents electron-hole recombination. 38 The enhanced photocatalytic activity is attributed to the synergistic actions between Ag nanoparticles and clusters in zinc oxide, where charge separation plays a dominant role. 39 Some studies have also shown that Ag plays an important role in making some semiconductor composites more catalytic.…”

Biological elastomer i.e., medium-chain-length poly-3-hydroxyalkanoate (mcl-PHA) and its graft copolymer were investigated for reactive coating application. They were composited with silver-doped zinc oxide (Ag-ZnO) to produce films with photocatalytic activities. The activities were assessed from the photodegradation efficiencies of methylene blue, Rhodamine B and Orange II dyes. The PHA composite films demonstrated sustained photocatalytic activities over repeated usage compared to neat PHA. The presence of Ag also inhibits microbial growth on the film surface. The composite film exhibited negligible toxicity effect when tested against Ceriodaphnia dubia. Potential and advantages of Ag-ZnO−PHA composite film in reactive coating applications are discussed.

“…The efficacy of photocatalytic degradation of textile dye waste from the textile sector in Gresik, Indonesia was evaluated using UV light. 5% Ag produced the highest deterioration efficiency, including pristine ZnO [15]. With an Ag/ZnO ratio of 10, the composite showed the maximum photocatalytic effectiveness for removing BPA under visible light irradiation [16].…”

Spray pyrolysis is a method for preparing nanocomposite materials in the gas phase. Due to the ease with which the temperature in the furnace can be controlled, this method can produce more uniform nanoparticle sizes. This method can be used to synthesize ZnO nanoparticles. Additionally, due to the photocatalytic properties of the synthesized particles, they are used to decompose synthetic dye waste. Due to electron-hole recombination, ZnO’s photocatalytic properties are limited. A doping process with various metals was used to enhance the photocatalytic properties of ZnO nanoparticles. Ag is one of these metals. The addition of Ag metal to ZnO nanoparticles results in the formation of nanocomposites with preferable photocatalytic properties. However, the addition of Ag results in the aggregation of the obtained particles. As a result, the ZnO particles must be trapped in a matrix (for example, SiO2) to inhibit particle growth. This research aims to determine the effect of the SiO2 composition on the characteristics and photocatalytic properties of ZnO/Ag/SiO2 nanocomposite synthesized via spray pyrolysis. SEM (Scanning Electron Microscope) analysis was used to determine the morphology of the nanocomposites, XRD (X-ray Diffraction) analysis was used to determine the purity and degree of crystallization, FTIR (Fourier-transform Infrared) analysis was used to determine the functional groups, and UV-Vis Spectrophotometer analysis was used to determine the photocatalytic characteristics. According to the analysis results, the optimal photocatalytic activity was obtained at 1% SiO2, with a degradation rate of up to 47% of methylene blue and a rate constant (k) of 0.0086 L/min under UV light irradiation.

“…However, these approaches require expensive vacuum equipment. ZnO thin films can be made less costly using spray pyrolysis, 24 screen printing, 25 chemical bath deposition, 26 electrochemical deposition, 27 and sol–gel spin coating. 28 The sol–gel method is a vacuum-free, safe, environmentally friendly, economic, easy process, and is more versatile.…”
