Photocatalytic and photo-electrochemical behavior of novel SnO2-modified-g-C3N4 for complete elimination of tetracycline under visible-light irradiation: Slurry and fixed-bed approach

Femtosecond laser irradiation as a novel method for nanosheet growth and defect generation in g-C3N4

“…The photocatalytic/absorptive results are plotted in figure 5, where C/C 0 is calculated as the percent decrease in concentration relative to the initially measured concentration (select spectral data available in S.7). Solution pH was measured at 7 ± 0.1 before and after dye degradation, which matched similar works [33,[57][58][59]. As pH strongly impacts the degradation and absorbance behavior of catalytic degradation systems, comparison between results is only meaningful at matched pH values [59][60][61].…”

Fly ash-, foundry sand-, clay-, and pumice-based metal oxide nanocomposites as green photocatalysts

“…[58][59][60][61][62] Among these strategies, immobilization technique using waste materials (ash and foundry sand) or natural materials (clay minerals and pumice) have been received extensive interest in recent years. [63][64][65][66][67] The benets of this technique are that it can: (i) easily recover and reuse catalysts from the treated effluent stream, (ii) support continuous operation for multiple cycles of photoreactors, and (iii) enhance the photodegradation efficiency of organic compounds from the aqueous solution. 13,68 More importantly, the use of natural or waste materials for xing metal oxides have received increasing attention.…”

Sunlight active cellulose/g-C3N4/TiO2 nano-photocatalyst for simultaneous degradation of methylene blue dye and atenolol drug in real wastewater

“…Whereas, the resultant nanocomposite exhibit a red shift with the absorption threshold extended up 480 nm and a reduced optical gap of 2.9 eV (figure 1(b)). Incorporating titania onto g-C 3 N 4 formed stable-heterojunctions between two nanomaterials and therefore shifted the absorption into visible region [21,22]. The E VB of TiO 2 and g-C 3 N 4 were calculated as +2.91 eV and +1.54 eV respectively, while the corresponding E CB were −0.29 eV and −1.26 eV.…”
