Optimization of the synthesis parameters of high surface area ceria nanopowder prepared by surfactant assisted precipitation method
Source abstract
Abstract
Abstract Response surface methodology (RSM) has been used to optimize the critical parameters responsible for higher surface area of ceria nanopowder prepared by surfactant assisted precipitation method. A three-level central composite design (CCD) was used to optimize pH, CTAB/metal molar ratio and calcination temperature. A quadratic model between response and the independent parameters was developed and the response surface model was tested with analysis of variance (ANOVA). The optimum operating conditions determined were a pH value of 9.4, CTAB/metal molar ratio of 0.5 and calcination temperature of 266 °C. Under these optimal conditions maximum surface area of 158 m2/g has been achieved.
