Synthesis and characterization of Ni-doped TiO2 activated carbon nanocomposite for the photocatalytic degradation of anthracene

Synergistic material modification-induced optimization of interfacial charge transfer and surface hydrogen adsorption

“…[10][11][12][13] For instance, high reserve transition metals (e.g., Fe, Co, Ni, and Al) with close ionic radii to Ti that allow successful implantation into the lattice of TiO 2 have been widely studied. 14 The strong electronic interaction between the transition metal atoms (such as Ni) and TiO 2 promotes the formation of the Ti 3+ /O V (oxygen vacancy) configuration 15 and the generation of Ti 3+ species, benefiting charge compensation and the formation of oxygen vacancies. 16 The synergistic effect of bi-Ti 3+ and O V is responsible for the high photocatalytic activity by promoting charge transfer and retarding recombination.…”

Sunlight light-driven degradation of anthracene and naphthalene on robust Cu2+doped ZnO nanoparticles from simulated rainwater: optimization factors, kinetics, and reusability

“…The comparative decline in the removal efficacy of the real sample compared to the control is caused by two factors: (i) the number of active species is limited according to catalyst dose, which removes both PAHs simultaneously; and (ii) the sample may contains other pollutants (PAHs, heavy metals, and pesticides) despite the NAP and ANT, which further suggests the effectiveness of nanocatalysts. 51–58 Hence, the Cu@ZnO photocatalyst proved to be an efficient sunlight-active catalyst for real samples.…”

“…The complete removal process is oen divided into two steps: initial adsorption of pollutants on nanocatalyst surfaces, and then photocatalytic disintegration by reactive oxygen species generated by the semiconducting characteristics of nanocatalysts. [50][51][52] The adsorption capacity of nanoparticles was increased by Cu doping due to the large surface area, which also allowed for the rapid transfer of ANT and NAP molecules to active sites. The valence (VB) and conduction (CB) band gap energies of photocatalysts are equivalent to or greater than that of the photons absorbed by the photocatalytic materials.…”
