Abstract

This study aimed to evaluate the relationship between the performance of electro-catalysis and the uniformity of molybdenum disulfide (MoS2) on carbon electrodes deposited according to three different coating methods, namely, drop-casting, brushing, and spraying. The electrochemical kinetics can be determined by how uniformly the catalyst is coated throughout the entire surface of the electrodes. Laser-induced breakdown spectroscopy was employed to investigate the uniformity and loading quantity of MoS2 on the electrode surface. The most uniform coating was achieved with the spraying method followed by brushing and drop-casting.
