Nanotechnological materials have enormous potential for various applications. The physical and chemical properties of nanomaterials are varied and depending on the size, structure, shape, and synthesis techniques. Sonochemistry is one of the potential synthetic techniques for producing noble nanomaterials. When an aqueous solution is exposed to ultrasound, acoustic cavitation generates both chemical and physical effects, inducing a chemical reaction. In this article, the sonochemical phenomenon, factors influencing sonochemical synthesis, reaction zone, and types of sonochemistry has been discussed. Sonochemistry contributes significantly to green synthesis using less toxic compounds and environmentally safe solvents. It is used for the treatment of water, solid state lighting, degradation of pollutants, production of hydrogen, clean and synthesis of nanomaterials (organic, inorganic and polymers). Ultrasound is also used as a highly effective sludge pretreatment technology in wastewater treatment plants to aid biogas production. This article also focuses on the discussion and advantages of the sonochemical technique over conventional coprecipitation and physical vapour deposition methods.
