The synthesis of ZnO architecture on a fluorine-doped SnO_2(FTO) conducting glass pre-coated with nanoporous TiO_2 film has been achieved by a one-step hydrothermal method at a temperature of 70℃.The effect of the reaction time on the morphology of the ZnO architecture has been investigated,and a possible growth mechanism for the formation of the ZnO architecture is discussed in detail.The morphology and phase structures of the as-obtained composite films have been investigated by field-emission scanning... 相似文献

Oxalic acid is a weak and unsymmetrical bi-basic acid. There exist dissociation and association equilibria among the species in aqueous solution. The molar conductivity of the solution is the sum of the ionic contributions.Based on this idea, a new prediction equation of ionic conductivity was proposed at low concentration. The molar conductivities of the solution and its relevant ions were calculated respectively. The results obtained were in good agreement with those from experiments and the Quint-Viallard equation. 相似文献
