SYNTHESIS OF HIGH-ACTIVITY C AEROGELS-BASED g-C3N4 PHOTOCATALYSTS DERIVED BY THE POLYMERIZATIONOF PF

[摘要] This paper details the synthesis of high-activity carbon (C) aerogels-based g-C3N4 catalysts for photocatalytic degradation under visible light. We seal and heat a mixture of phenol (P),ZnCl 2 and g C 3 N 4 solvated by formaldehyde, obtaining the mixture of an intimateinteraction betw e en phenol formaldehude (PF) and g C 3 N 4 as precursor of C aerogels-based g C 3 N 4 . The post thermal treatment results in not only carbon doped g C 3 N 4 which improve the π-conjugation system to profit the separation of photo-induced carrier, but also obtainingC aerogels which possess high surface area. The resulted C aerogels-based g C 3 N 4 catalysts shown high adsorption capacity (78 mg/g), broadened light absorption, improvedphotoelectrochemical performance and higher photocatalytic properties compared with pristine g C 3 N 44.
