Abstract With the increase of drug‐resistant bacteria and limitations traditional antibacterial methods, photocatalytic inhibition has received widespread attention as a novel method. In this paper, poly(1‐vinyl‐3‐ethylimidazolium tetrafluoroborate) composite oxygenated carbon nitride (PBF‐OCN) were prepared by in situ free radical polymerization using 1‐vinyl‐3‐ethylimidazolium tetrafluoroborate OCN. The results showed that light absorption ability electron hole separation rate PBF‐OCN greatly improved compared with OCN, constant for removal MB PBF‐OCN‐1 was about 1.39 times growth Escherichia coli ( E. ) Staphylococcus aureus S. could be significantly inhibited under visible light, among which, PBF‐OCN‐3 most excellent, diameter circle reaching 20.69 mm , 21.30 against calculated plate counting method reached 97.0%. minimum inhibitory concentration 0.0625 mg/mL, respectively, possible mechanism samples explored. good synergistic effect is expected to applied water treatment, devices, packaging materials, other fields.

ABSTRACT The low photogenerated charge carriers and quick complex annihilation of titanium dioxide (TiO 2 )/rGO composite leading to an unsatisfactory photocatalysis antibacterial effect limit its application in the bone scaffold. Herein, graphitic carbon nitride (g‐C 3 N 4 ) was assembled with TiO /rGO via a solvothermal method for enhancing properties poly (lactic acid) (PLLA) scaffold prepared selective laser sintering. results revealed that g‐C expanded light absorption range from blue‐violet visible light, resulting composites having narrower band gap producing more photoinduced carriers. More importantly, S‐scheme heterojunction formed between , which promoted recombination electrons conduction holes valence . Meanwhile, rGO excellent electrical conductivity reduced interfacial transfer resistance enhanced efficiency, thus further avoiding rate holes, whether or photocatalytic properties. Consequently, possessed high oxidation reduction capacity, oxidized H O microenvironment, respectively, generated lots reactive oxygen species. In vitro experiments indicated PLLA/TiO /g‐C showed better effect, bacteriostasis rates E. coli S. aureus being 99.1% 98.9%, respectively. addition, cell adhesion fluorescence had good biocompatibility could provide suitable microenvironment growth proliferation cells.

Abstract In this study, Fe 3 O 4 nanoparticles were deposited on graphitic carbon nitride (g‐C N ), which was subsequently functionalized with sulfonic acid groups, resulting in a magnetically separable solid catalyst. The synthesized catalyst comprehensively characterized using FT‐IR, EDX, XRD, TEM, VSM, elemental analysis, and acid–base titration to assess its structural properties, surface morphology, acidity. Its catalytic performance evaluated the ring‐opening reaction of epoxides alcohols, demonstrating excellent substrate versatility efficiency for alcoholysis various epoxides. inclusion enabled facile recovery an external magnet. Furthermore, exhibited remarkable reusability, maintaining consistent activity over four successive cycles negligible decline.

Cuprous oxide (Cu2O) has great potential in photodynamic therapy for implant-associated infections due to its good biocompatibility and photoelectric properties. Nevertheless, the rapid recombination of electrons holes weakens antibacterial effect. In this work, a new nanosystem (Cu2O@rGO) with excellent performance was designed via situ growth Cu2O on reduced graphene (rGO). Specifically, rGO lower Fermi levels served as an electron trap capture photoexcited from Cu2O, thereby promoting electron-hole separation. More importantly, surface could quickly transfer owing conductivity, thus efficiently suppressing pairs. Subsequently, Cu2O@rGO nanoparticle introduced into poly-L-lactic acid (PLLA) powder prepare PLLA/Cu2O@rGO porous scaffolds through selective laser sintering. Photochemical analysis showed that photocurrent increased by about two times after incorporation GO nanosheets, enhancing efficiency photogenerated charge carriers Moreover, ROS production scaffold significantly compared PLLA/Cu2O scaffold. The results possessed rates 83.7% 81.3% against Escherichia coli Staphylococcus aureus, respectively. summary, work provides effective strategy combating implant-related infections.
