Abstract

Abstract:

Oxidized nanocellulose(TOCN) was prepared by 2, 2, 6, 6-tetramethylpiperidine-1-oxy radical(TEMPO)-oxidation using bleached wood pulp as raw material. Aerogel TOCN/rGA was prepared by combining by TOCN with reduced graphene oxide(rGO). On this basis, the photocatalytic aerogel Ag/AgCl/g-C₃N₄@TOCN/rGA was prepared by loading the catalyst Ag/AgCl/graphite phase carbon nitride(g-C₃N₄) on the aerogel, and the aerogel was used for adsorption and degradation of Rhodamine B(RhB). The structure and morphology of the aerogel was characterized by FT-IR, SEM, and TEM. The photocatalytic mechanism of the aerogel was investigated by XPS, DRS, PL, transient photocurrent, active substance capture experiments and energy band structure calculation. Moreover, the adsorption, photodegradation, mechanical strength and antibacterial properties of the aerogel were analyzed. The results showed that Ag/AgCl/g-C₃N₄@TOCN/rGA was successfully prepared with abundant porous results. The good electrical conductivity of rGO effectively inhibits the recombination of Ag/AgCl/g-C₃N₄ photogenerated carriers. Compared with Ag/AgCl/g-C₃N₄, Ag/AgCl/g-C₃N₄@TOCN/rGA has stronger visible light absorption, lower photogenerated carrier recombination rate, and higher transient photocurrent density. The loading of Ag/AgCl/g-C₃N₄ also increases the equilibrium adsorption capacity and mechanical strength of the aerogel: the equilibrium adsorption capacity of Ag/AgCl/g-C₃N₄@TOCN/rGA for RhB is 2.86 mg/g, which is higher than that of TOCN/rGA at 2.72 mg/g. At 70% strain, the compressive strength of Ag/AgCl/g-C₃N₄@TOCN/rGA is 0.86 MPa, which is higher than that of TOCN/rGA at 0.62 MPa. Ag/AgCl/g-C₃N₄ interacting with TOCN/rGA obtains excellent degradation effects: the degradation rate of RhB by Ag/AgCl/g-C₃N₄@TOCN/rGA is 95.1% for 180 min at pH=7, and 80.5% for RhB after 4 cycles of irradiation, and the inhibition rate of Escherichia coli was 100% for 120 min. The results of free radical capture experiment show that superoxide radical(O₂^-) is the main active substance of composite aerogel photocatalysis.
