“…The common precursor is cerium nitrate hexahydrate and the reaction environment is alkaline (seen in Table 1). [44][45][46][47][48] Other precursors and capping agents are still in research and development.…”

Facile synthesis of CeO2 nanoparticles for enhanced removal of malachite green dye from an aqueous environment

“…However, the predominant factors in the precipitation techniques as reported in most of the reports are the use of surfactant or similar additives, toxic solvents and harsh conditions like high temperature and prolonged reaction times. [55][56][57][61][62][63] Considering the disadvantages associated with the existing reported synthesis protocol of CeO 2 NPs by co-precipitation method, the specific objectives of this study were to were purchased from Sigma-Aldrich, India. Sodium hydroxide (NaOH), hydrochloric acid (HCl) and nitric acid (HNO 3 ) were purchased from Merck, India.…”

“…50,51 Due to its wide range of applications, researchers are focusing more on synthesizing CeO 2based materials of controlled size, shape, and morphology as the size, shape, and morphology significantly affect the physicochemical properties and hence their application potential. [52][53][54][55] Accordingly, different chemical approaches such as precipitation, [55][56][57] sol-gel, 48 hydrothermal, 58,59 thermal decompositions, 49 and solution combustion 60 have been extensively used for the synthesis of CeO 2 NPs. However, researchers put more emphasis on the precipitation method because the precipitation approach is the simplest, most environmentally friendly, most cost-effective, and easy to scale up.…”

“…However, the predominant factors in the precipitation techniques as reported in most of the reports are the use of surfactant or similar additives, toxic solvents and harsh conditions like high temperature and prolonged reaction times. [55][56][57][61][62][63] Considering the disadvantages associated with the existing reported synthesis protocol of CeO 2 NPs by the co-precipitation method, the specific objectives of this study were to synthesize CeO 2 NPs of different sizes via the co-precipitation method without using any toxic solvents or additional stabilizers. Furthermore, literature surveys showed that the adsorptive removal of malachite green using metal oxide, or their composites is not very effective in terms of the performance of the adsorbents.…”
