Multi-elemental doped g-C3N4 with enhanced visible light photocatalytic Activity: Insight into naproxen Degradation, Kinetics, effect of Electrolytes, and mechanism

TiO2-modified g-C3N4 nanocomposite for photocatalytic degradation of organic dyes in aqueous solution

“…To examine the rate of recombination of charge carriers in the synthesized photocatalysts, photoluminescence (PL) analysis was conducted at the excitation wavelength of 340 nm. Higher emission intensity in PL spectra indicates a high recombination probability [ 48 ]. Figure 6 exhibits the PL emission spectra of pristine g-C 3 N 4, TiO 2 /g-C 3 N 4 nanocomposite, and pure TiO 2 .…”

Understanding the Principles and Applications of Dual Z-Scheme Heterojunctions: How Far Can We Go?

“…44 For example, induction of defect-assisted charge transfer at the interface with doping and direct contact-induced electric field boosts the charge separation rate and transportation across the interface of semiconductors (Figure 5). 18 The modulation of optical properties may include the selection of semiconductor components with strong absorption index in the different regions of the solar spectrum for an all-spectrum responsive catalyst. The selection of a semiconductor with strong UVresponse with others that possess strong visible light absorption and/or near-infrared spectral response will ensure that the heterojunction photocatalyst absorbs light at all spectral wavelengths.…”

Modulation of Z-scheme photocatalysts for pharmaceuticals remediation and pathogen inactivation: Design devotion, concept examination, and developments

“…However, Mott-Schottky plots are more clearly used to further elucidate and complement the radical trapping experiments. In our previous work, we showed the use of M-S plots to portray formation of direct Z-scheme heterojunction between ceria and CN [54] . The M-S plots were used to give the band structure while the radical trapping experiments gave information on most active radicals which were used together to show existence of direct Z-scheme charge transfer between CN and ceria.…”
