چکیده
Multi-functionalized and co-doped TiO2/C nanocomposites were derived from the pyrolysis of Ti-MOFs at 800 °C under different gaseous atmospheres their photocatalytic performance investigated. The atmosphere during plays a critical role in determining structural, textural, optical physicochemical properties composites due to synergistic effect nitrogen-containing species, carboxylate sulfur functionalized porous carbon as well N/S TiO2 nanoparticles. All exclusively possess homogeneously distributed nanoparticles disc-like matrix demonstrate much enhanced adsorption photodegradation than commercial same conditions. methylene blue (MB) dark on these are dominated with pseudo second-order kinetic model high capacity MB composite MIL-125(Ti) argon is its surface area predominant mesoporous composite. N-O-TiO2/C NH2-MIL-125(Ti) water vapor exhibited highest activity 99.7% removal 3 h visible light optimal anatase/rutile phasejunction, together formation photoactive oxygen-rich N-O like interstitial/intraband states above valence band TiO2, presence N-containing species -OH/-COOH multi-functional groups superhydrophilic nature This simple one-step easily modifiable approach can be further employed modulate dispersed multi-functionalized metal oxide/carbon for various environment energy-related applications.
