Construction of single-atom Ag embedded O, K co-doped g-C3N4 with enhanced photocatalytic efficiency for tetracycline degradation and Escherichia coli disinfection under visible light

Ag2S nanoparticles anchored on P-doped g-C3N4: a novel 0D/2D p-n 2 heterojunction for superior photocatalytic inactivation of 3 multidrug-resistant E. coli

“…The smaller arc radius means a higher separation efficiency of photogenerated carriers [50]. Figure 10(b) presented the EIS Nyquist plots of the tested samples, and Ag 2 S/PCN-5 possessed minimum arc radius compared to CN and PCN, which reflected the huge reduced transfer resistance of free charges and elevated charge transfer ability [51]. From the photocurrent response spectra in figure 10(c), Ag 2 S/PCN-5 exhibited the optimal photocurrent intensity and was increased about 2.5 and 2.0 times more than CN and PCN, which was also in accordance with the excellent photocatalytic inactivation performance.…”

Carbon nitride based materials: more than just a support for single-atom catalysis

“…Among many modifications of CN-based materials, Ag single-atoms are one of the most chosen for pollutant degradation and water treatment. 17,24,310,413,438,446,520,522,524 Partially due to their well-documented antimicrobial activity, which was explored by Lu et al , Ag embedded in O,K doped g-C 3 N 4 proved to increase the disinfection of water in the presence of E. coli bacteria under light irradiation for 60 minutes. 520 Besides its natural potential as an antimicrobial agent, Ag synergizes well with CN materials demonstrating capabilities of degradation of persistent molecules and antibiotics.…”

Ag modification in this CN system led to an increase in the surface area, but more importantly, increased light absorption, while suppressing charge recombination.…”

Recent Progress of Single‐Atom Photocatalysts Applied in Energy Conversion and Environmental Protection

“…Photocatalysis is a promising strategy for eliminating antibiotics and pathogens from aquatic environments with the advantages of environmental friendliness, efficiency, low cost, and stability. [198] Wang et al innovatively loaded Ag SAs and carbon quantum dots (CQDs) onto ultrathin g-C 3 N 4 (SDAg-CQDs/UCN) for the degradation of NPX in a broad spectrum using a synergistic SPR and up-conversion strategy. [199] Ultrathin g-C 3 N 4 could be excited by light with wavelengths less than 473 nm to generate electron-hole pairs.…”
