- 2001年第7卷 
应用XRD、SEM、循环伏安法 (CV)等测试手段研究了钙对氮化钼膜电极性能的影响 .结果表明 ,采用浸渍_煅烧法制备电极 ,浸渍液中添加剂的量对电极电化学性能的影响显著 ;当添加剂的量为最佳值时 ,电极的比电容约为不加添加剂制备之电极的 2 .1倍 ,工作电势拓宽了 0 .11V .钙对γ_Mo2 N膜电极电化学性能的影响机理可认为是电极新生物质CaxNy、晶粒规整化和电极活性物质吸附能力增强这三种因素的协同作用The effect of calcium on the properties of molybdenum nitride film electrode was studied by using XRD, SEM and cyclic voltammetry. The results show that the specific electric capacity and the voltage operating range of electrode vary with the concentration of additive in the dipping solution. At the optimum concentration of additive in the dipping solution, the specific electric capacity of the electrode is 2.1 times as large as that of the electrode prepared in the dipping solution without additive, and the voltage operating range of electrode is increased by 0.11 V. The active mechanism of calcium on the properties of film electrode suggested the synergism of the crystal grain regularized and the adsorbability of the film electrode improved and the new phase Ca xN y formed in the film electrode of molybdenum nitride.
