Hydrogen is an ideal clean energy carrier and can be produced by decomposition of water using a photoelectrochemical cell (PEC) technique. The PEC technique relies on the use of photoelectrode materials and graphitic carbon nitride (g-CN) is a promising metal-free candidate for that. Here, we propose to study the chemical reaction involved in hydrogen production from seawater using g-CNphotoelectrode materials. To facilitate qualitative and quantitative analysis and optimize experimental parameters, we will carry out the photocatalysis study of synthetic seawater which contains deionized water added with some amounts of NaCl, magnesium chloride, magnesium sulfate, calcium sulfate, potassium sulfate, potassium carbonate, and magnesium bromide preparation. In testing the photolysis properties of seawater, NaCl concentrations and pH values of synthetic seawater will be tuned in order to understand the influence of seawater composition on the photocatalytic properties and photostability of electrodes, laying the foundation for photocatalysis of natural seawater.
