Abstract

A facile, economic, and reproducible chemical bath deposition (CBD) method is developed for the fabrication of facet-controlled Ag{sub 3}PO{sub 4} thin films with enhanced visible light photocatalytic activity. The fine-control of bath temperature, precursor, complexing agent, substrate, and solution pH is fairly crucial in preparing the facet-selective thin film of Ag{sub 3}PO{sub 4} nanocrystal. The change of precursor from silver nitrate to silver acetate makes possible the tailoring of the crystal shape of Ag{sub 3}PO{sub 4} from cube to rhombic dodecahedron and also the bandgap tuning of the deposited films. The control of [Ag{sup +}]/[phosphate] ratio enables to maximize the loading amount of Ag{sub 3}PO{sub 4} crystals per the unit area of the deposited film. All the fabricated Ag{sub 3}PO{sub 4} thin films show high photocatalytic activity for visible light-induced degradation of organic molecules, which can be optimized by tailoring the crystal shape of the deposited crystals. This CBD method is also useful in preparing the facet-controlled hybrid film of Ag{sub 3}PO{sub 4}–ZnO photocatalyst. The present study clearly demonstrates the usefulness of the present CBD method for fabricating facet-controlled thin films of metal oxosalt and its nanohybrid. - Highlights: • The crystal facet of Ag{sub 3}PO{sub 4} films can bemore »« less

Light-dependent controlled synthesis and photocatalytic properties of stable Ag{sub 3} nanocrystals

Journal Article Wang, Jian-Dong; Liu, Jin-Ku; Luo, Chong-Xiao; ... - Materials Research Bulletin

The silver phosphate (Ag{sub 3}PO{sub 4}) is applied in organic matter photodegradation as a novel catalyst materials, however, its instability reduces the photocatalytic life and limits its further applications. In this work, a series of Ag{sub 3}PO{sub 4} crystalline nanoparticle clusters have been synthesized by a photocontrol method. By comparing their sunlight photocatalytic properties, the Ag{sub 3}PO{sub 4} nanoparticles with dominant (2 2 0) facets have a lower surface energy (1.05 J m{sup −2}) than existing Ag{sub 3}PO{sub 4} crystals which can offer a longer catalyst service life. The photodegradation rate of the Ag{sub 3}PO{sub 4} nanoparticles is about 3more »« less
