Nano-scaled silver vanadates loaded on mesoporous silica: Characterization and photocatalytic activity

Construction of stable core–shell imprinted Ag-(poly-o-phenylenediamine)/CoFe2O4 photocatalyst endowed with the specific recognition capability for selective photodegradation of ciprofloxacin

“…S6B † shows that the XRD pattern of the sample aer 5 cycles was nearly the same as that of the initial sample, demonstrating that the crystalline structure of imprinted Ag-POPD/CoFe 2 O 4 was not changed during the photocatalytic reaction. In addition, the photoluminescence (PL) spectra 58,59 were further investigated to conrm the reproducibility, as shown in Fig. S7.…”

Photocatalytic degradation of binary mixture of toxic dyes by HKUST-1 MOF and HKUST-1-SBA-15 in a rotating packed bed reactor under blue LED illumination: central composite design optimization

“…Photoluminescence spectroscopy is a useful technique for surveying the separation efficiency of the photogenerated charge carriers in semiconductors; the higher the PL intensity, the larger the probability for charge carrier recombination. 27,28 Therefore, a comparison of the PL spectra of HKUST-1 and the HKUST-1-SBA-15 composite at room temperature was carried out and the results are shown in Fig. 4c.…”

A Novel, Simple and Green Way to Fabricate BiVO4 with Excellent Photocatalytic Activity and Its Methylene Blue Decomposition Mechanism

“…Therefore, a low PL intensity implies a low electron-hole recombination rate under light irradiation [42]. Figure 6 shows the room temperature PL spectra of BiVO 4 synthesized under different conditions.…”
