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.

“…Remarkably, the surface plasmon resonance (SPR) absorption bands of the Ag NWs are significantly weakened and broadened, and there is a new characteristic absorption feature of the CdS crystals with a weak band-gap absorption band at around 490 nm, which is similar to the reported 489 nm adsorption of CdS NWs 42 and 468-496 nm adsorption of CdS nanoparticles. 43 The spectral results observed herein could possibly reflect contributions to the synergistic effects between the Ag NWs and CdS shell in the Ag@CdS hybrids and provide strong evidence that the Ag NWs have essentially turned into Ag@CdS hybrids, with the product mainly composed of the CdS component, 44 as well as suggesting that the good contact between the Ag core and CdS shell might ensure effective charge transfer across the phase boundary and cause changes in the structure and shape of the product. 45,46 Their broad absorbance from the UV to the near-infrared window is crucial for the full use of sunlight.…”

Constructing one-dimensional (1D) hierarchical photocatalysts is deemed to be central to promoting photocatalytic capacity. In this paper, 1D hierarchical structures composed of CdS nanosheets/nanoparticles on Ag nanowires (denoted as 1D Ag@CdS core-shell hierarchical hetero-nanowires) have been fabricated via a wet-chemistry approach at low temperature. The optimization of the synthetic parameters indicates that the amounts of Cd(NO 3 ) 2 ·4H 2 O and thiourea play important roles in the construction of the 1D hierarchical structures. The as-prepared 1D hierarchical Ag@CdS core-shell hetero-nanowires exhibit efficient photocatalytic performance in both methyl orange (MO) degradation (degrade 96% of MO within 240 min) and hydrogen generation (73.5 μmol h -1 ) from water splitting due to the unique hybrid nano-architecture. It is expected that this Ag@CdS hierarchical nanostructure could have potential in solar energy conversion and this fabrication technique could be used as a reference to design other 1D metal@semiconductor core-shell heteronanowires.

“…The precursors used for the decomposition were air and moisture stable at room temperature. The AACVD of CdS thin films using the pyridine adduct of bis(piperidinedithiocarbamato) cadmium(II) complex was also reported [39]. In this work, we report the use of piperidine (1) and tetrahydroquinoline (2) dithiocarbamato cadmium(II) complexes as single source precursors for the deposition of CdS thin films at different temperatures by AACVD.…”
