2D Catalyst Materials for Seawater Electrolysis

Why watch it?

Green hydrogen electrolysis relies on scarce fresh water, while salts, particles and microbes in seawater disrupt it. Suraj Loomba, a Royal Society of Victoria Young Scientist award recipient, presents noble-metal-free alternatives to Pt/C and IrO2 developed with his team: N-NiMoO3 sheets for hydrogen evolution and Co-MOF heterostructured WO3.B2O3 sheets for oxygen evolution. According to the description, they suppress chlorine, stay stable for months in alkaline seawater and could be 50–60 times cheaper at scale; unverified claims.
