Special Issue Information

Dear Colleagues,

Photocatalysis is an emerging and promising technology involving the activation of a semiconductor by UV or visible light, with artificial light sources or natural sunlight. Considered as a laboratory process for many years, it is now enjoying development resulting from simultaneous efforts by research laboratories and industrials in the search for innovative solutions to the environmental treatment (liquid and gaseous effluents and surfaces) or for the energy production and storage. However, in many applications, it is essential to immobilize the semiconductor on a suitable support to form a photocatalytic film or develop incorporated materials. This is particularly the case for the air treatment, self-cleaning surfaces, but also for the H2 production by water splitting on a semi-industrial scale.

This Special Issue is devoted to “Photocatalytic Surfaces for Environmental Applications”. In particular, the topics of interest include, but are not limited to:

  • Photocatalytic surfaces for depollution of water, air and soil;
  • Immobilized photocatalysts, novel substrates and functionalized surfaces;
  • Structured hybrid photocatalysts (adsorbent-photocatalysts, cementitious materials, etc.);
  • Self-cleaning surfaces;
  • Novel Vis photocatalysts;
  • H2 production by water splitting;
  • Energy storage;
  • Antimicrobial surfaces;
  • Protection of buildings, contruction materials;
  • Solar applications.

In this paper, we present the results of a computational study of the electrical and photovoltaic properties of a perspective composite material; that is, layered composite films of covalently bonded graphene and single-walled carbon nanotubes (SWCNTs). The purpose of the study is to identify the topological patterns in controlling the electrical and photovoltaic properties of mono- and bilayer graphene/CNT composite films with a covalent bonding of a nanotube and graphene sheet, using in silico methods. This in silico study was carried out for the super-cells of mono- and bilayer graphene/CNT composite films with the CNTs (10,0) and (12,0) at distances between the nanotubes of 10 and 12 hexagons. This found that the type of conductivity of the nanotubes does not fundamentally affect the patterns of current flow in the graphene/CNT composite films. This control of the diameter of the nanotubes and the distance between them allows us to control the profile of the absorption spectrum of the electromagnetic waves in the range of 20–2000 nm. The control of the distance between the SWCNTs allows one to control the absorption intensity without a significant peak shift. This revealed that there is no obvious dependence of the integrated photocurrent on the distance between the nanotubes, and the photocurrent varies between 3%–4%. Full article
