软嵌式薄层粉末电极 I: 薄层粉末旋转电极和光电化学电极

研究粉末电催化剂目前多采用多孔电极(如气体扩散电极)方法, 也用糊状电极或粉末悬浮液方法, 但均不适于研究电极过程动力学.为了研究粉末催化剂, 我们制备了软嵌式超薄层粉末旋转盘环电极和光电化学电极. 这种电极制备简单, 实验数据重现性良好, 能广泛用于各种电极过程动力学研究.

Electrodes with surface-intercalated powder of catalysts I: Rotating ring powder electrodes and photoelectrochemical electrodes

A novel method was established to enhance the study of electrocatalytic behavior of powdered catalysts. An ultrathin layer of fine graphite powdered catalyst was intercalated into the surface layer of a soft conductive plastic sheet made from acetylene black and PTFE binder. This technique was successfully used in preparing catalytically active electrodes, i.e. for rotating disk and rotating ring-disk electrode systems. Powdered semiconductors used as catalysts in photoreactions can also be studied in the same manner.
