Facile Construction Engineering of PrO@C with Efficient Photocatalytic Activity.

In this study, facile construction engineering of PrO@C with efficient photocatalytic activity was established. Taking advantage of the flocculation of Pr in the base medium, acid red 14 (AR14) was flocculated together with Pr(OH) precipitate, in which Pr(OH) and AR14 mixed highly uniformly. Calcinated at high temperature in N2, a novel PrO@C was successfully synthesized.
