Cr2 WO6纳米晶的水热法制备及其对亚甲基蓝的选择性吸附性能
Hydrothermal synthesis Cr2 WO6 nanocrystallites with selective adsorption properties to methylene blue in water
摘要
Abstract
Cr2 WO6 nanocrystallites with particle morphology were successfully synthesized by using Cr(NO3 )3 · 6H2 O ,Na2 WO4 · 2H2 O as raw materials and deionized water as solvent via a hydrothermal method .The phase composition ,morphologies and optical performances of the as‐prepared samples were characterized by XRD (X‐ray diffractometer) ,SEM (Scan‐ning electron microscope) ,EDS (Energy dispersive spectrometer ) and Lambda 950 spectro‐photometer and the influence of different pH value on the structure and the selective adsorp‐tion properties of the products were investigated .Results show that the acid‐base property of precursor has an obvious effect on the phase of Cr2 WO6 nanocrystallites under the hydrother‐mal conditions ,in which the Cr2 WO6 nanocrystallites could only be obtained with weak acid‐ity of the reaction system .In addition ,the Cr2 WO6 nanocrystallites were found to exhibit ob‐vious higher selectivity and superior activity to adsorb methylene blue than conventional cal‐cined products .关键词
