Nanoparticles were physically attached to photodegradation applications. Nanoparticles are particles of sizes within the range of 1 to 100 nm with at least one dimension. Nanoscale structures, for example, nanolayers and nanoparticles, have an extremely high surface-to-volume ratio, making them perfect for employing in different materials for various applications. In general, In case of nanometers, nanoparticles are categorized into organic, inorganic, and carbon-based particles in nanometric scales that have enhanced characteristics in contrast with micrometric or larger sizes of individual materials. The nanoparticles appear upgraded characteristics, for example, surface area, high surface reactivity (bioactive), and high quality, also appeared stable, sensitive, and so on due to their smaller sizes. Different methodologies are used to synthesize the nanoparticle materials for research studies and traditionally utilizes. These techniques are ordered into three principal types to be specific chemical, physical and mechanical procedures that have seen a tremendous improvement after some time. This article covers the fundamentals of nanotechnology, nanoparticle types, synthetic methodologies, the use of metal, metal oxides, and carbon-based nanoparticle in the field of photocatalysis, and the development of using nanomaterials in air purification and environmental protection. Herein, a variety of synthetic strategies for nanomaterials are summarized, including their applications as photocatalysts.
