Constructing Z-scheme g-CN/TiO heterostructure for promoting degradation of the hazardous dye pollutants.

The use of dyes and segments has increased widely in recent years, but it poses a serious health risk to ecosystems. In this work, TiO and two-dimensional g-CN nanosheets (g-CN) were fabricated through co-precipitation and thermal polymerization technique, respectively. The g-CN-TiO photocatalyst (1: 3, 2: 2, 3: 1) in various weight percentages was prepared using a simple impregnation process.

Silica nanoparticles derived from Arundo donax L. ash composite with Titanium dioxide nanoparticles as an efficient nanocomposite for photocatalytic degradation dye.

Water pollution is a serious problem that threatens both developed and developing countries. Several methods have been used to purify contaminated water, among which the photocatalytic decomposition approach is widely used to purify contaminated water from organic pollutants. In this work, biomass derived SiO nanoparticles composite with TiO semiconductors used as an efficient photocatalyst for degradation of RhB dye molecules under UV-visible light irradiation is proclaimed.
