    • A method of making silica-layered double hydroxide microspheres having the formula I : (i) wherein, Mz+ and M'y+ are two different charged metal cations; z = 1 or 2; y = 3 or 4; 0 0, q > 0, Xn- is an anion; with n > 0 a = z(1-x) + xy-2; and the AMO-solvent is an 100% aqueous miscible organic solvent; comprises the steps: (a) contacting silica microspheres and a metal ion containing solution containing metal ions Mz+ and M'y+ in the presence of a base and an anion solution; (b) collecting the product; and (c) optionally treating the product with AMO-solvent and recovering the solvent treated material to obtain the silica-layered double hydroxide microspheres. Preferably, M in the formula I is Li, Mg, Ni or Ca. Preferably, M' in formula I is Al. The invention further provides silica-layered double hydroxide microspheres having the formula I. The silica-layered double hydroxide microspheres may be used as catalysts and/or catalyst supports.
    • 一种制备具有式I的二氧化硅层状双氢氧化物微球体的方法:(i)其中,Mz +和M'y +是两种不同的带电金属阳离子; z = 1或2; y = 3或4; 0 0,q> 0,Xn-是阴离子; 其中n> 0 a = z(1-x)+ xy-2; 并且AMO-溶剂是100%水溶混性有机溶剂; 包括以下步骤:(a)在碱和阴离子溶液存在下,使二氧化硅微球和含有金属离子Mz +和M'y +的含金属离子溶液接触; (b)收集产品; 和(c)任选用AMO-溶剂处理产物并回收溶剂处理的材料以获得二氧化硅层状双氢氧化物微球。 式I中的M优选为Li,Mg,Ni或Ca. 式I中的M'优选为Al。 本发明进一步提供具有式I的二氧化硅层状双氢氧化物微球体。二氧化硅层状双氢氧化物微球体可用作催化剂和/或催化剂载体。
