Anodically deposited Mn-Mo-o electrodes by direct and pulse current as novel anode materials for hydrogen production during seawater electrolysis

Hydrogen is currently well recognized as a future fuel. Its production from seawater electrolysis using electroactive anode is presented in this study. Mn-Mo-O which is known for its efficiency as well as environmentally benign nature is used in this work. Direct and pulse electro-deposition methods were applied for preparation of the Mn-Mo-O electrode. Variation of both direct and pulse current. using sulfuric MnSO4-Na2MoO4 electrolyte solutions were the basis of the experiments. The electrodes were characterized by X-Ray Diffraction [XRD], Scanning Electron Microscopy [SEM] and electrochemical measurements. The performance of the electrodes were evaluated in 0.5M NaC1 electrolyte solution by electrolysis at 1000 Am[-2]. The findings indicated that pulse electrodeposition provide anode materials with better activity and durability as compared to direct electrodeposition method. The results are discussed in terms of structure, composition and mechanical properties of the anodes
