Cover story: Solar photoreforming of aqueous oxygenated pollutants on exfoliated C₃N₄ enables hydrogen production. Process efficiency is boosted by judicious C₃N₄ precursor selection, exfoliation method to enhance active surface area, and most critically, maximising Pt co-catalyst dispersity into the nanometre and atomic dispersion regime. Even increasingly recalcitrant pollutants, from alcohols to polyglycols, can be converted without catalyst deactivation, demonstrating a promising route for wastewater valorisation and clean energy generation.
