摘要/Abstract

摘要： 以ZnO纳米颗粒为原料，十二烷基硫酸钠（SDS）水溶液作造孔剂，利用我们独有的液态溶剂热压方法制备了ZnO多孔纳米块体. 实验结果表明，通过调控SDS溶液的浓度,可以调节ZnO多孔纳米块体的结构参数. 当SDS的浓度达到4.34×10^-1mol/L时，ZnO多孔纳米块体的孔道空间分布均匀性最好，孔径分布也最窄. 另外，红外分析结果表明，在液态溶剂热压制备ZnO多孔纳米块体过程中，SDS在ZnO多孔纳米块体的孔道中有微量残留.

Abstract: ZnO bulk porous nanosolids were successfully prepared by a novel liquid solvothermal hot press method using ZnO nanoparticles and sodium dodecyl sulphate (SDS) solution as the starting materials. The results show that the pore structure parameters of ZnO bulk porous nanosolids could be adjusted by changing the concentration of the SDS solution. At the beginning, the uniformity of the pore diameter improved with an increase of the concentration of the SDS solution and it reached its maximum at a concentration of 4.34×10^-1mol/L. If the concentration is increased further, the uniformity of the pore diameter is again decreased. In addition, the FTIR spectra of ZnO bulk porous nanosolids indicate that a few SDS molecules remaine in the pores of the ZnO bulk porous nanosolids.

Key words: ZnO bulk porous nanosolids , ZnO nanoparticles, SDS solution, liquid solvothermal hotpress
