The BiVO4 with surface heterojunction is synthesized via additives-free low temperature aqueous method. The formation of co-exposed {0 1 0} and {1 1 0} facets of BiVO4 follows the nucleation-Ostwald ripening growth process. The DFT calculations shows that the {0 1 0} and {1 1 0} facets can form surface heterojunction, therefore, the co-exposed {0 1 0} and {1 1 0} facets of BiVO4 exhibit highest photocatalytic...
OH) played key roles in RhB degradation. Moreover, on the basis of the calculated energy bands, the obviously enhanced photocatalytic performance can be attributed to the efficient separation of photoinduced electron–hole pairs. In addition, the calcination improved the crystallinity of C-Bi2WO6/BiVO4, combined with the excellent photoabsorption ability further improved its photocatalytic activity...
