摘 要

当下我国对能源的消费量越来越大，近几年对能源的使用量更是大大的增加，对于新能源的开发将是我国在未来几年甚至几十年履行的职责。我们对新能源的探究也进入到了一定的阶段。Ca₃Co₂O₆的电催化受到了广泛关注，钴氧化合物有着特殊的电催化析氢和析氧特性。为了比较各种合成样品方法，我们通过溶胶-凝胶法合成Ca₃Co₂O₆。之后对其材料进行表征性能分析。测试X射线衍射分析，C-V曲线，LSV曲线和TAFEL斜率。通过氧化还原性能还有其他表征来进而推断Ca₃Co₂O₆的电催化。一旦发现Ca₃Co₂O₆材料的电催化强于其他材料，将为我国在新能源探究工作上起到重要的帮助。能源问题是全世界一个不可避免的问题，不可再生能源迟早有一天会被消耗殆尽，而且大部分的不可再生能源带给地球的污染过于严重。我们对清洁能源的渴望越来越强烈。而先前国外对Ca₃Co₄O₉的析氢以及析氧的探究得到的结果还是比较乐观的。利用钴氧化物探索清洁能源的思想更进了一步。

Abstract

The present our country of energy consumption is more and more big, for energy use is greatly increased in recent years, for the development of new energy will be our country in the next few years or even decades of duties. Our exploration of new energy has also entered a certain stage. The electrocatalysis of Ca₃Co₂O₆ has been widely concerned, and cobalt oxide compounds have special characteristics of electrocatalytic hydrogenation and oxygen dissociation. In order to compare various synthetic sample methods, Ca₃Co₂O₆ was synthesized by sol-gel method. Then the characterization of the material was analyzed. Test X-ray diffraction analysis, c-v curve, LSV curve and TAFEL slope. The electrocatalysis of Ca₃Co₂O₆ was inferred from the REDOX performance and other characterization. Once Ca₃Co₂O₆ is found to be more electrocatalytic than other materials, it will play an important role in China's exploration of new energy resources. The energy problem is an inevitable problem in the world. Sooner or later, the non-renewable energy will be used up. Our desire for clean energy is growing stronger and stronger. However, the results obtained from previous foreign studies on Ca₃Co₄O₉ hydrogenation and oxygen evolution are extremely optimistic. The idea of using cobalt oxide to explore clean energy followed.

Key words: Energy; Electric-catalytic; Hydrogen Evolution; Oxygen Evolution; Ca₃Co₂O₆
