| Popis: | The global water crisis limits the full implementation of purified water electrolysis across the world. Thus, seawater electrolysis has been identified as a powerful option to meet the requirements for sustainable production of green hydrogen without the constraint of using pure water. As in pure water electrolysis, seawater electrolysis research has been oriented to produce a durable, electrocatalytic, and selective anode. Even though seawater electrolysis was proposed for the first time in 1980, the research found on this topic grew exponentially in the last few years. Nevertheless, researchers do not give a clear insight about the impact that important variables have in the process of seawater electrolysis and, in particular, the anodic process. In this work, an in-depth literature review on articles reporting the development of various anode materials and the conditions in which they have been tested was carried out. The conclusions reveal a need to standardize some parameters for testing the anodes, such as simulated seawater composition, pH of the solution, the method through which parasitic reactions are measured and the choice of secondary reactions to be considered in the process. A standardization of these parameters will allow researchers to compare results, which in turn will allow collaborative work towards the goal of finding a feasible process for seawater electrolysis. |
