Abstract
Palladium dithiocarbamate precursors have been designed for the fabrication of palladium sulphide photoelectrode films using aerosol assisted chemical vapour deposition.
Highlights
palladium sulphide (PdS) is a widely explored material and has been largely synthesized in powder forms as well as nano-crystals using a variety of methods
The PdS thin films were deposited on FTO conducting glass substrates at 400, 450 and 500 1C by the aerosol-assisted chemical vapour deposition (AACVD) technique and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) reveal that the deposit has a tetragonal structure with a 1 : 1 ratio of Pd : S
To the best of our knowledge, this is the first demonstration of PEC studies of photoactive PdS thin films fabricated using the AACVD technique using palladium(II) dithiocarbamate complexes as precursors
Summary
PdS is a widely explored material and has been largely synthesized in powder forms as well as nano-crystals using a variety of methods. Nano-crystals have been synthesized by solvothermal or thermal decomposition of palladium(II) xanthate and allyl palladium(II) xanthate complexes.[14] The aqueous dispersions of. PdS particles have been prepared by the addition of Na2S solution to PdCl2 or Na2PdCl4 solutions.[15] Organosols of PdS have been synthesized by the reaction of metal acetate with hydrogen sulphide.[16] relatively few reports have been published on the deposition of PdS thin films using either a chemical vapour deposition (CVD) or a non-CVD technique. The single source precursor (SSP) based CVD synthetic approach has been identified as a potential route for the fabrication of tailormade thin films that can meet the technology demand in
