“…By adopting a suitable synthesis method, one can regulate the structural, chemical and surface morphology, and particle size of a material to be used in the desired technical applications. Nowadays, numerous methods are available to synthesize mixed metal oxide based thin film coatings or nanoparticle structures namely, hydrothermal process, chemical co-precipitation route, laser deposition method, polyol process, thermal decomposition method, electrochemical method, microwave assisted technique, standard ball milling scheme, sol-gel dip coating or spin coating procedure, and thermal evaporation approach [42][43][44][45][46][47][48][49]. The majority of these synthesis methodologies, generally, require complicated working procedures, higher reaction temperatures, high cost machineries, higher energy consumption, longer reaction times, and harmful and toxic organic reagents.…”
