摘要： 在完全不可逆电极反应体系(氧和亚硫酰氯还原)中研究了粉末微电极的行为。可以用微多孔电极模型解释测得的实验结果, 粉末微电极技术可以广泛用于研究各种粉末催化剂的电催化行为并可能制备高灵敏、响应快的微型电化学传感器。

Abstract: The behaviors of powder microelectrodes for irreversible reduction of oxygen and thionyl chloride were studied. The postulation that micro-powder electrode is equivalent to a microelectrode with highly active and extended surface was supported by experimental results. This techniques could be widely applicable to the study of electrochemical behaviors of various powder electro-catalysts and to the construction of microelectrodes with fast-response and sensitivity.
