By a facile solid‐state reaction method with urea as a nitrogen source , HNb 3 O 8 could be successfully doped with nitrogen without destroying its layered structure. It was found that the intercalation of urea not only helps to stabilize the layered structure of HNb 3 O 8 during the heating process, but also facilitates an easier doping of nitrogen into the solid acid. The nitrogen‐doped HNb 3 O 8 photocatalyst so‐obtained shows fairly good activity under visible light irradiation.
