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.Savy和Putten等人曾制备了薄层粉末电极,但是,前者实验结果不易重现,后者适用范围较窄,因而应用在电化学研究中受到了限制. 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. 薄层粉末旋转盘环电极在制备软嵌电极时,关键是选择一个有塑性的防水导电膜.为 Study of powder electrocatalysts currently used porous electrode (such as gas diffusion electrode) method, also used paste electrode or powder suspension method, but not suitable for the study of the electrode process kinetics.Savy and Putten have prepared thin powder electrode However, the former is not easy to reproduce the experimental results, the latter has a narrow range of applications, and thus the application of electrochemical research has been limited.In order to study the powder catalyst, we prepared a soft-embedded ultra-thin layer of powder rotating disk ring electrode and photoelectrochemistry This electrode is simple to prepare, good reproducibility of experimental data, can be widely used in a variety of electrode process kinetics. Thin-layer powder rotating disk electrode in the preparation of soft embedded electrodes, the key is to choose a plastic waterproof conductive Membrane
