“…As can be seen in the figure, the morphology of BiVO 4 comprised of a spherical particle bumpy surface with the average particle size and thickness of ∼357–680 nm and ∼556 nm, respectively. As film was deposited under similar conditions to those reported previously , the results showed a variation in thickness and morphology. The thicker film obtained in the current work absorbs more light and contributes to the increase of electron transitions between the valence and conduction bands .…”

Thin-film bismuth vanadate, BiVO 4 photoanode was fabricated on fluorine-doped tin oxide via aerosol-assisted chemical vapor deposition, AACVD, with ethylene glycol as a solvent. The structure and morphology of the BiVO 4 thin film were analyzed using X-ray diffraction and field emission scanning electron microscopy and found to have monoclinic clinobisvanite structure with a noncompact nanoparticle distribution. The optical properties and bandgap estimation showed the BiVO 4 thin film exhibited a characteristic peak in the visiblelight region with bandgap energy of 2.43 eV. The photoelectrochemical properties were investigated in a 0.5 M Na 2 SO 4 electrolyte without any sacrificial agent or electron/ hole scavenger resulting in 0.73 mA cm À2 at 1.23 V vs. SCE.The electrochemical impedance spectroscopy revealed good charge-transfer characteristics of the photoanode and the Mott-Schottky plot was used to estimate the conduction and valence-band position of BiVO 4 .

“…34). 248 Bismuth vanadate has a band gap of 2.4 eV in the monoclinic scheelite phase 249 and is considered one of the most promising anodic semiconductor materials for PEC, not least because of its stability in pH neutral conditions. The photocurrent density was reported as 1.8 mA cm À1 at 0.23 V versus Ag|AgCl, with a direct bandgap of 2.74 eV, making it potentially better than TiO 2 , since it absorbs a greater proportion of the solar spectrum and exhibits less recombination.…”

This critical review focuses on the solution based chemical vapour deposition (CVD) of main group materials with particular emphasis on their current and potential applications. Deposition of thin films of main group materials, such as metal oxides, sulfides and arsenides, have been researched owing to the array of applications which utilise them including solar cells, transparent conducting oxides (TCOs) and window coatings. Solution based CVD processes, such as aerosol-assisted (AA)CVD have been developed due to their scalability and to overcome the requirement of suitably volatile precursors as the technique relies on the solubility rather than volatility of precursors which vastly extends the range of potentially applicable compounds. An introduction into the applications and precursor requirements of main group materials will be presented first followed by a detailed discussion of their deposition reviewed according to this application. The challenges and prospects for further enabling research in terms of emerging main group materials will be discussed.

Sustainability is an increasingly important topic in the design and manufacture of materials, with the need to reduce the environmental impact of producing materials being of paramount significance. A competing interest to this is the ability to produce functional materials in large volumes from a fast, on-line process, which can be integrated easily into existing industrial setups. Herein, we present aerosol-assisted chemical vapour deposition (AACVD) routes to advanced functional materials. We will show that by careful design of precursors and manipulation of deposition conditions, it is possible to achieve high sustainability whilst maintaining fast growth rates and large scale production of thin film functional materials.
