NOVELTY - Use of molybdenum carbide/nitrogen -doped carbon as a cocatalyst for photocatalyst. USE - The molybdenum carbide/N-doped carbon as a cocatalyst in the preparation of photocatalyst (claimed). ADVANTAGE - The photocatalyst has high efficiency photocatalytic water to prepare hydrogen activity, overcomes the problem that the noble metal co-catalyst cost is high, the storage amount is small, and it cannot be applied in large scale.
