Electrochemical water splitting is a clean and efficient method for hydrogen production, involving two half-reactions: hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). In the HER, two electrons are transferred from the electrode to the protons in the analyte solution to produce hydrogen gas (H2), and the electric current is also generated. Electrocatalysts act on the surface of electrodes and play a critical role in increasing efficient hydrogen production. This study aims to find low-cost and high-efficient electrocatalysts to replace expensive platinum-based nanoparticles. Hence, we studied the catalytic activity of metal-doped ZnO nanoparticles and monolayer-protected gold nanoclusters (MPCs). The current and on-set potential, which can be obtained by linear sweep voltammetry (LSV), are two key factors in evaluating the performance of electrocatalysts. The results showed that nickel doping did not improve the catalytic activity and could not be considered as the optimal electrocatalyst. We also compared the catalytic activities of MPC with three different ligands, Au140(S(CH2)5CH3)53, Au140(S(CH2)10COOH)53, and Au140(SCH2CH2Ph)53. The slight difference in current and on-set potential suggested that all three nanoclusters could be used as electrocatalysts to control the HER. In addition, the catalytic activity could be improved with water as a solvent, gold as a working electrode, and analyte solution at high concentrations.
