Bimetallic Manganese Cobalt Phosphide Nanodots–Modified Graphitic Carbon Nitride for High-Performance Hydrogen Production

It is a huge challenge for exploiting new photocatalysts with low-cost cocatalysts in place of precious metals to realize high-efficiency H 2 production from water. Herein, a new photocatalyst with a high H 2 production activity is prepared via modification of bimetallic manganese cobalt phosphide (Mn 0.67 Co 1.33 P) nanodots on graphitic carbon nitride (g-C 3 N 4 ). Moreover, the largest H 2 production rate of 113.1 μmol h −1 is obtained over the Mn 0.67 Co 1.33 P/g-C 3 N 4 -5 sample, which is about 2.75 times than that of Pt/g-C 3 N 4 -5 (41.2 μmol h −1 ). The high-performance H 2 production suggests page a page down that the modification effect of Mn 0.67 Co 1.33 P nanodots improves the visible harvest ability and separation efficiency of charge carriers. A typical example to improve the photocatalytic H 2 production performance by fabricating heterostructures using bimetallic phosphide to modify graphitic carbon nitride is provided.
