ZnO nanoparticles (NPs) are effectively produced using a straightforward, efficient, high-yield, and inexpensive mechanochemical combustion process at various calcination temperatures. The impact of calcination temperature on ZnO nanocomposites’ crystallinity has been investigated using X-ray diffraction (XRD). The synthesized ZnO and Ag/ZnO’s XRD patterns show a well-crystalline wurtzite ZnO crystal structure. The ZnO NPs peak position obtained at 300–600 ◦C calcination temperatures is nearly identical to the peak position of ZnO obtained at a temperature without calcination. This paper has discussed the hydrothermal method of ZnO NPs production and photodepostion of Ag-doped ZnO NPs. Additionally, the behavior of the ZnO and Ag/ZnO nanocomposites is thoroughly examined in relation to the effects of calcination temperature on Transmission Electron Microscopy (TEM), Field Emission-Scanning Electron Microscopy (FE-SEM), Energy Dispersive Spectroscopy (EDS), and the measurement of specific surface area using the Bruner, Emmett, and Teller method.The absorption efficiency changed from 99.87% to 72.55% when the concentration of BB dye was increased from 10 to 50 ppm. Increasing the intensity of the UV light will improve the photocatalytic degradation and absorbance efficiency (PDE%) efficiency because the catalyst will receive more radiation, which will lead to the production of more hydroxide radicals .The photocatalytic efficiency increases from 77.7% to 97.7% in 1 h.
