Enhancing the photocatalytic H 2 evolution activity of red phosphorous by using noble-metal-free Ni(OH) 2 under photoexcitation up to 700 nm

Ni(OH)2 nanoparticles are demonstrated to be cost-efficient alternatives to Pt co-catalysts for enhancing the visible-light photocatalytic H2 evolution activity of red phosphorous (P) when deposited onto its surface. Ni(OH)2-modified red P exhibits 1.12 times higher photocatalytic activity for H2 evolution than that of Pt-deposited red P under a wide range of visible light.
