Effect of synergic cooperation on optical and photoelectrochemical properties of CeO₂–MnO composite thin films

Abstract

Low-temperature (475 °C) fabrication of CeO2–MnO composite thin films having a band gap of 2.5 eV by AACVD.

Fabrication of pristine Mn2O3and Ag–Mn2O3composite thin films by AACVD for photoelectrochemical water splitting

“…We have investigated several manganese oxide based photocatalysts such as Mn 2 O 3 -4TiO 2 , 20 Mn 2 O 3 -TiO 2 , 21 MnO 2 -CeO 22 and solid solution of MnZnO 3 23 and found them advantageous for PEC water splitting applications. These studies revealed that the coupling of two semiconductors might result in improved interfacial charge transfer thereby minimizing charge recombination, lowering the band gap and ultimately boosting photo-activity in the visible region.…”

Photoelectrochemical properties of p-type CuBi2O4 prepared by spray pyrolysis of carbon-free precursor aqueous solution combined with post-annealing treatment

“…The reason for the formation of pores in the as-deposited film can be interpreted by the basis of homogeneous and heterogeneous nucleation processes similar to the metal oxide composite-based thin films prepared using an aerosol-assisted chemical vapor deposition technique. [57][58][59] In the present study, the deposition temperature (substrate temperature) was kept at 400 1C, producing the mixture of Cu oxide and Bi subnitrate that have different pyrolysis temperatures (see Fig. S5, ESI †).…”

Recent Advances in Processing and Applications of Heterobimetallic Oxide Thin Films by Aerosol‐Assisted Chemical Vapor Deposition

“…The change in thin microstructure with temperature was explained based on homogeneous and heterogeneous nucleation. [67]…”

“…The schematic representation for the photoelectrocatalytic activity of Mn 2 O 3 −TiO 2 composite thin films and the corresponding photoelectrochemical responses are depicted in Figure 3. In another study by Mansoor et al., [67] CeO 2 −MnO composite thin films were deposited by using dual precursor strategy, i. e., a self‐designed cerium complex, [Ce(TFA) 4 ] [dmaeH]+ and commercially available Mn(OAc) 2 (OAc=acetate). Thin films were grown at 450, 475, and 500 °C.…”

“…The films produced at 500 °C formed higher voids than those at 450 and 475 °C. The change in thin microstructure with temperature was explained based on homogeneous and heterogeneous nucleation [67] …”
