摘　　要：多孔材料具有大比表面积、高孔隙率、高的透过性、可组装性、高吸附性等诸多性能。在有害气体吸附分离、色谱分离材料、环境污染处理、催化材料、催化载体等领域均有广泛应用。同时，多孔材料具有比致密材料更为优越的物理、机械和热性能。制备形貌和尺寸可控的多孔材料引起了人们的高度关注。One-dimensional porous zinc oxide was prepared via the calcination of zinc oxalate precursor obtained by solvothermal method. The products were characterized by XRD, SEM, TEM, photoluminescence （PL） spectrum and nitrogen adsorption-desorption. The results show that the obtained zinc oxide sample is porous and constructed by nanoparticles about 30 nm in size. The specific surface area and total pore volume are 126 m^2·g^-1 and 0.13 cm^3 ·g^-t, respectively. The PL properties related with defects in ZnO nanoparticles were discussed for porous zinc oxide samples.
