A one-step cation exchange process has been applied for the first time to the fabrication of nanoporous Ba-doped Ag₃PO₄ hollow nanosheets using Ba₃(PO₄)₂ as the starting material. The constituent-dependent changes in phase and morphology were investigated comprehensively to elucidate the nanosheet formation mechanism. The resultant Ba-doped Ag₃PO₄ hollow nanosheets exhibited much higher photocatalytic performance and photoconversion efficiency than Ag₃PO₄ cubes and spherical particles under visible light irradiation. More importantly, the photocatalyst exhibited unique preferential decomposition of methyl orange over rhodamine B and high photocatalytic stability under visible light irradiation.
