研究概要
Hydrogen is expected to be the future fuel amidst the ongoing rapid depletion of fossil fuels and the negative environmental impacts thereof. However, a sustainable way of producing hydrogen depend largely on the electrolysis of water. Electrolysis of water is an energy intensive process that must be catalyzed with catalysts of appropriate structure and property to ensure energy efficiency while also ensuring that they are abundant. Here, we propose to develop non-precious metals-based anion-tailored chalcogenide and phosphide catalysts supported on respective metal foils for both water reduction and oxidation electrocatalysis. This is to be achieved by our in-house methodologies (chemical anion pre-oxodation of metal chalcogenides and phosphides and electrochemical hydroxylation with concurrent anion oxidation and surface amorphization). Prospective metals to be used include Ni, Co, Fe, Mo, Cu and W and the catalysts of interest will be sulphide, selenide, telluride, and phosphide of all the above said metal. With this, we intend to lower the potentials of water oxidation and reduction reactions closer to 1.48 and 0.00 V vs. RHE, respectively.
