摘要：二十一世纪，对于人类发展和社会进步来说，能源的高效利用与转化至关重要。氢气有其特定的优点,若能使电解水制氢工业化，利用电解水的方法制备氢气可实现能源的可持续发展，因此开发具有高稳定性和高催化效率的催化剂十分重要。本论文制备了一种高效稳定无贵金属的电化学析氢催化剂，由硝酸铁和双氰胺在乙醇溶剂中络合得到产物，然后在烘干的前提下，置于管式电阻炉中800 ℃煅烧，最后高温分解为Fe2O3 的纳米粒子将负载于碳材料上，得到催化材料。该催化剂在碱性条件（1.0 mmol KOH溶液中）下有较低的的电化学电势（塔菲尔曲线的斜率为86 mV/dec），电化学阻抗分析得到催化剂的电阻为8 Ω，在电化学析氢中表现出较快的电子传递速率和较高的感应电流效率。同时在碱性条件下表现出较好的的稳定性，是一种前景非常广阔的无贵金属析氢催化剂。因此可以认为采用N掺杂的碳材料负载Fe的纳米颗粒具有催化析氢的作用，且能有效的提高析出氢气的速率。

Study on catalyst that is composed of mental and N element supported on carbon material for electrochemical hydrogen evolution reaction

Abstract: It is of crucial importance that the efficient use and transformation of energy for human development and social progress in the 21st .Hydrogen is popular with scientists for  its specific advantages that its production raw materials account for 71% of the earth's surface. It is possible to achieve sustainable development of energy if the way of hydrogen evolution reaction is applied in industrialization. Therefore, it is significant to develop catalysts with high stability and high catalytic efficiency.In this experiment, a kind of electrochemical hydrogen evolution catalyst with high stability and no precious metal was prepared. The product was obtained by complexation of ferric nitrate and dicyandiamide in ethanol solvent, and then placed in a tube .It was under the 800 °C with resistance temperature under the premise of drying. Finally,Fe2O3 that are pyrolyzed to nanoparticles will be loaded on the carbon material to obtain a catalytic material.The catalyst has a lower electrochemical potential under basic conditions  (the slope of the Tafel plot is 86 mV/dec in the 1.0 mmol KOH solution). The electrochemical impedance analysis shows that the resistance of the catalyst is 8 Ω. Chemical hydrogen evolution reaction shows faster electron transfer rate and higher induction current efficiency. At the same time, it shows good stability under alkaline conditions. It is a promising catalyst for hydrogen evolution without noble metals.Therefore, we believe that the catalyst loaded with N-doped carbon have catalytic hydrogen evolution.And it can effectively increase the rate of hydrogen evolution.
