Synthesis of Y-doped CeO2/PCN nanocomposited photocatalyst with promoted photoredox performance

Design and Synthesis of Sm, Y, La and Nd‐doped CeO2 with a broom‐like hierarchical structure: a photocatalyst with enhanced oxidation performance

“…The results indicate that rare earth ions doping can induce narrowing of the band gap of CeO 2 . A smaller band gap energy (E g ) is considered to be one of the crucial parameters for determining the final photocatalytic performance . The doping of cations can favor the formation of trivalent cerium (Ce 3+ ) and create more oxygen vacancies (O v ).…”

Experimental and theoretical investigation of the tuning of electronic structure in SnO2viaCo doping for enhanced styrene epoxidation catalysis

“…48 The presence of a large amount of lower valent Sn 2+ species suggests the transformation between the valence states of Sn and the generation of abundant OV in the doped sample due to the charge imbalance induced by the substitutional doping of Co into the SnO 2 frameworks. 49,50 By estimating the areas that the fitted curves cover, the Sn 2+ /Sn 4+ molar ratio in the Co-SnO 2 is determined to be 0.55, which is prominently larger than that in the P-SnO 2 (0.14). Interestingly, the binding energies of the Sn 3d peaks in the Co-SnO 2 exhibit negative shifts as compared with those of the P-SnO 2 , revealing the occurrence of electronic regulation triggered by the hetero-atom doping effect.…”

Facile Synthesis of CeO2/CoWO4 Hybrid Nanocomposites for High Photocatalytic Performance and Investigation of Antimicrobial Activity

“…To characterize the trapping, charge migration, excitation properties, and separation efficiency of photo-excited charge carriers of the as-attained samples, they were further investigated by via PL emission spectra inquiry. 33 The room-temperature PL spectra of the CeO 2 /CoWO 4 heterojunction NCs, pristine CeO 2, and CoWO 4 NPs are shown in Fig. 7.…”
