Boosting photosynthetic biogas upgrading via carbon-coated zero-valent iron nanoparticle addition: A pilot proof of concept study

Environmentally friendly loading of palladium nanoparticles on nanoporous PET track-etched membranes grafted by poly(1-vinyl-2-pyrrolidone) via RAFT polymerization for the photocatalytic degradation of metronidazole

“…Graing of PET TeMs (with a surface of 2 cm 2 ) was carried out in a 10 mL of aqueous polymerization solution containing various amounts of monomer, N-vinyl pyrrolidone, VP (10,20,30,40,50 w/v%) and xanthate-based RAFT agent, CPPA, for time periods ranging from 60 to 600 min ([VP]/[CPPA]) = 1/1000. Reaction mixtures were put into sealed asks and degassed with argon for 5 min.…”

“…Metal oxide NPs such as titanium dioxide (TiO 2 ), 37 zinc oxide (ZnO), 38 and iron oxide (Fe 3 O 4 ), 39 have been extensively studied for their ability to adsorb and degrade various pollutants including metronidazole. Zerovalent metal NPs such as iron NPs, 40 copper NPs, 41 palladium NPs 42 have also been shown to be effective in removing metronidazole.…”
