Abstract

This study aimed to evaluate the relationship between the performance of electro-catalysis and the uniformity of molybdenum disulfide (${\mathrm{MoS}}_2$) 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 ${\mathrm{MoS}}_2$ on the electrode surface. The most uniform coating was achieved with the spraying method followed by brushing and drop-casting.
