摘要
以尿素为沉淀剂用均匀沉淀法直接合成有机阴离子柱撑水滑石(LayeredDoubleHydroxides,LDH)及CoAl水滑石等,并用XRD,FT-IR,TGA,TEM等分析手段对所合成的水滑石进行了表征.结果表明,尿素均匀沉淀法可以直接合成有机阴离子柱撑水滑石及CoAl水滑石等,并且可以方便地消除原料中阴离子的干扰,是合成有机阴离子柱撑水滑石及CoAl水滑石等的一个简便快速的新方法.
Layered double hydroxides (LDH) pillaring with organic anions CoAl-LDH are directly synthesized by a homogeneous precipitation method using the urea as a precipitiant,and the LDH products have been characterized through XRD,FT-IR,TGA and TEM.The results of all investigations show that urea homogeneous precipitation is a quick and simple method to obtain LDH pillaring with organic anions and CoAl-LDH,and can avoid the influence of anions in reactants.
