多孔碳酸钙微粒的简易制备及其形貌控制
Facile Synthesis and Morphology Control of Porous CaCO3 Microparticles
摘要
Abstract
Porous CaCO3 microparticles were prepared with sodium carbonate and calcium nitrate in the presence of poly (sodium styrenesulfonate) (PSS) in aqueous solution under room temperature, and their morphology was characterized by FE-SEM. The results show that the particle size and morphology of the microparticles can be controlled by changing the concentrations of PSS and reactants. When 0.5 g⋅L−1 PSS and 0.025 mol⋅L−1 reactant concentrations were applied, the microparticles synthesized have a uniform size of ~1.2μm. XRD and BET results show that the porous CaCO3 microparticles were composed of vaterites and calcites. With the increase of reactant concentration, the nano-pore diameter in the porous CaCO3 microparticles decreases, but the specific surface area increases significantly.关键词
