Research On Preparation Of Nanometer-scale Oxides By The Electrochemistry Method

Science and Technology of nanoscale materials have entered into the highly developing phase that have brought human into the new field of realizing and researching the new materials since 1980s. Every country has regarded science and technology of nanoscale materials as one of the new fields of firstly—developed high—tech and new materials. As the nanoscale materials take on the characteristics of quantum dimension domino offect,small dimension domino offect,surface domino offect and macro quantum tunnel domino offect being different from reality materials,they are abroad applied in the fields of chemical catalyzing,pottery,medicine,environment protection,national defence,etc. Nowaday every country has committed itself to researching preparation methods and their industrialization,exploiting and exploring their particular characteristics of physics,chemistry and mechanics,etc,so that they will be made better to serve national economy. Their subjects have become the most important goals of the developments of every country's science and technology. This paper has studied to make use of the electrolyzing method in both chambers that is divided by anion—exchanging membrance based on the past ways of nanoscale materials being invented , to produce the depositions of hydrate and hydrated oxide which are calcined to become the nanoscale oxides.This method possesses the characteristics of simple equipments , facile operation, cheap materials,etc. The particles of the nanoscale oxides are uniformly distributed and small size in process of producing with being easily controlled, thus this newly productive method is provided for making the nanoscale oxides.This paper successively chooses Zn²⁺,Al³⁺,La³⁺,Ce⁴⁺,Mg²⁺ and TiO₂⁺ to make their nano-structured oxides based on the upwards...
