Nanomaterials semiconductors

As for the size dependence of nonlinear optical properties of semiconductor nanomaterials, detailed investigations are required from both the theoretical and experimental points of view. 

This section covers environmental applications of nanomaterials insofar as they are directly applied to the pollutant of interest. The photocatalytic degradation of organic pollutants and remediation of polluted soils and water are discussed here. The high surface areas and photocatalytic activities of semiconductor nanomaterials have attracted many researchers. Semiconductor nanomaterials are commercially available, stable, and relatively nontoxic and cheap. Prominent examples that are discussed are metal oxides such as Ti02 and ZnO and a variety of Fe-based nanomaterials. 

The process begins with the synthesis of different semiconductor nanomaterials (e.g., single-walled carbon nanotubes and single-crystalline nanowires/...

However, it is only recently that the potential benefits of combining sonochemistry with electrochemistry have increasingly been studied. It should be noted that electrochemical methods, mainly electrodeposition, are well established for the preparation of metals and semiconductor nanomaterials (for a review see Mastai et al. [146]).

Recently, an alternative strategy has been adopted to synthesize metal or semiconductor nanomaterials by exposing precursor metal-organic frameworks (MOFs) to an electron beam. Jacobs et al. (2011) demonstrated the formation for ZnO particles with narrow and tunable size distributions using different Zn-based MOFs. They showed that the composition, size, and morphology of the nanoparticles are determined by the chemistry and structure of the MOF, as well as the electron beam properties. 

Nanostructured wide bandgap materials functionalized with Pd or Pt are even more sensitive than their thin film counterparts because of the large surface-to-volume ratio (Lim et al, 2008 Johnson et al, 2009). 1-D semiconductor nanomaterials (such as carbon nanotubes (CNTs), Si nanowires,...
