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 μmol 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 H2 evolution.
