“…Therefore, for improving the photocatalytic activity of TiO2 in visible lights, its surface should be modified [56]. The catalytic activity of TiO2 can be improved by placing suitable materials on the surface of TiO2 for its application under visible irradiation [53,57,58]. Metallic particles such as Pd, Pt, Fe, Ru, Au, and Ag can be utilized on the TiO2 surface to improve the photocatalytic activity by suppressing recombination behaviors of e -/h + .…”

This review article provides useful information on TiO2 and ZnO photocatalysts and their derivatives in removing organic contaminants such as different types of dyes, hydrocarbons, pesticides, etc. Also, the reaction mechanism of TiO2 and ZnO photocatalysts and their derivatives was investigated. In addition, the impact of adding metallic (e.g., Ag, Co, Pt, Pd, Cu, Au, Ni) and non-metallic (e.g., C, N, O, S) dopants to their structure on the photodegradation efficiency of organic compounds was thoroughly studied. Moreover, advantages and disadvantages of various synthesis procedures of ZnO and TiO2 nanocatalysts were discussed and compared. Furthermore, the impact of photocatalyst dosage, photocatalyst structure, contaminant concentration, pH, light intensity and wavelength, temperature and reaction time on the photodegradation efficiency was studied. According to previous studies, adding metallic and non-metallic dopants to the TiO2 and ZnO structure led to a remarkable enhance in their stability and reusability. Besides, doped TiO2 and ZnO demonstrated remarkable photocatalytic efficiencies in eliminating various types of organic contaminants.

“… 6 Realizing the benefits of a high surface area, research shifted toward various metal sheets, foams, gaze structures, and ultimately nanomaterials. 7 Aerogels, with their three-dimensional non-ordered structure of interconnected nanochains, are one final form of this process. They exhibit a ligament size (diameter of a nanochain) as small as a few nanometers/several atoms, hence scratching on the physical limit defined by the atom size.…”
