A MOF-derived Bimetallic Co-catalyst for Promoting Visible-light Photocatalytic Hydrogen Evolution on NH₂-MIL-125

In order to construct noble metal-free co-catalysts to facilitate the transport and separation of photocatalyst carriers, herein, a MOF-based derived bimetallic NiCu0.2 co-catalyst was loaded on NH2-MIL-125(Ti). The obtained NiCu0.2/NH2-MIL-125 exhibited a photocatalytic activity of 161.4 mu mol g(-1) h(-1) for hydrogen evolution, 12.6 times higher than that of the Ni/NH2-MIL-125 and even slightly better than Pt/NH2-MIL-125. The work expands the development pathway of cost-effective and highly active bimetallic co-catalysts for photocatalytic H-2 evolution.
