Novel Ag/cellulose-doped CeO2 quantum dots for efficient dye degradation and bactericidal activity with molecular docking study

Experimental and Computational Study of Zr and CNC-Doped MnO2 Nanorods for Photocatalytic and Antibacterial Activity

“…To investigate PL spectra of the prepared samples at room temperature, a wavelength of 280 nm was employed for excitation. 39 In PL spectra, an observed peak of CNCs was located ∼427 nm and a broad peak in the range of 440–500 nm. However, MnO 2 , CNC-MnO 2 , and Zr/CNC-MnO 2 have the same spectra and exhibit a strong blue shift, which may be assigned to an oxygen-vacancy-related defect generated by electron and hole recombination.…”

“…Moreover, MnO 2 and CNC-MnO 2 showed lower PL intensity with a lower recombination rate, which is responsible for lower photodegradation efficiency. 39 However, material with rod-like one-dimensional morphology showed the best catalytic oxidation of dyes due to a large surface area with the highest concentration of adsorbed oxygen. The catalytic performance of different morphology of manganese oxide was in descending order such that rod-like > tube-like > flower-like > wire-like > bulk.…”

MoS2/cellulose-doped ZnO nanorods for catalytic, antibacterial and molecular docking studies

“…Resulting solution was heated at 100 °C to acquire solid content of cellulose nanocrystals (CNC) (Fig. 1a) [20,21].…”

“…In the present study, a quartz cell was filled with 400 µL solution of NaBH 4 and 3 mL aqueous methylene blue. Upon addition of NRs into solution containing NaBH 4 and MB, dye degradation was observed as depicted in Fig.2[20]. In order to acquire absorption spectra at different intervals, UV-vis spectroscopy was employed at wavelength ranging from 200-700 nm.…”

Synthesis and defect characterization of hybrid ceria nanostructures as a possible novel therapeutic material towards COVID-19 mitigation

“…In another work, CeO 2 nanoparticles were synthesized by the sol–gel method using MCC as a template and a specific surface area 5.5 times higher than that of the pure ceria for the catalytic ozonation of phenol, resulting in a removal efficiency of 69.2% and 49.5% for the modified and pure systems, respectively 37 ⁠. In contrast, Ag/cellulose nanocrystal-doped CeO 2 QDs were prepared by the co-precipitation method for the degradation of methylene blue and ciprofloxacin (MBCF), reaching a 99.3% degradation with a concentration of 4% Ag dopant 38 ⁠.…”
