Studies on electrochemical behavior of LaNi4.7Al0.3 single micro-particle electrode

A new single micro-particle electrode (SMPE) fabrication technique. the inlaid SMPE technique was.. introduced in this., paper. The: preparation procedure of an alloy SMPE was described in detail. Based on the SMPE technique, the electrochemical behavior of LaNi4.7Al0.3 spherical particles with two different radii was investigated. The results of CV study showed that more detailed electrochemical. information. of the alloy can be provided on the alloy SMPE as compared with that on-the composite alloy electrode. The results of potential step study depict,that H. diffusion coefficient in LaNi4.7Al0.3 keeps almost constant when the size. of the alloy particle changes, and the diffusion coefficient measured on the alloy SMPE [(2.5-2. 6) x 10(-9 cm2)/s] is about one order larger than that detected on the composite. alloy electrode.
