UV-light-driven photocatalysts of metal-organic frameworks based on acylamide-inserted multi-carboxylic acid

Abstract

Abstract Two functional metal-organic frameworks (MOFs), [Zn·L]·[ + H 2 N(CH 3) 2 ] 2 (DMF) 0.5 (H 2 O) 3 (1) and [Cu 2 L(H 2 O) 2 ]·xG (G = solvent molecule) (2) [H 4 L = bis(3,5-dicarboxypheny1)terephthalamide] were synthesized under solvothermal conditions. Their photoresponses in the UV region make them promising candidates for photodegradation of Rhodamine B (RhB) under UV light irradation. We studied the photocatalytic activities of the two MOFs and polyaniline (PANI) composite materials (named PANI/MOFs), which were prepared by loading the PANI on the surface of MOFs. The results indicate that PANI/MOFs composite materials exbibit excellent photostabilities and higher photocatalytic activities than the pure MOFs photocatalysts for degradation/removal of organic pollutants from wastewaters.
