Abstract

Abstract:

In order to solve the harm of HCHO gas released by indoor decoration and the problem of resource utilization of waste wind turbine blades，S-doped 2.0% nitrogen-rich carbon nitride（2.0% S-C₃N₅） photocatalyst was prepared by in-situ thermal polymerization using 3-amino-1，2，4-triazole as precursor and thiourea as sulfur source.X-ray diffraction（XRD），Fourier transform infrared spectroscopy（FT-IR），N₂ adsorption-desorption，UV-vis diffuse reflectance spectroscopy（UV-vis DRS），steady-state fluorescence spectroscopy（PL），electron paramagnetic resonance spectroscopy（EPR），transient photocurrent spectroscopy（TPC） and electrochemical impedance spectroscopy（EIS） were used to characterize the phase，group，specific surface area，spectral absorption，photoelectron-hole recombination，defects and electrochemical properties of the photocatalyst.After S doping，the efficient separation of photoelectron-holes and the enhancement of spectral response were achieved，which effectively improved the photocatalytic activity of C₃N₅ and achieved efficient removal of HCHO.The removal rate of HCHO reached 94.97%.The FRP filler concrete prepared by using the glass fiber reinforced resin matrix composite（FRP） after physical crushing of waste wind turbine blades as the reinforcing filler was used as the matrix，and the silicate cement paste doped with 2.0% S-C₃N₅ was used as the photocatalytic coating to construct the FRP reinforced concrete loaded with 2.0% S-C₃N₅ cement coating.The removal rate of HCHO by 2.0% S-C₃N₅ doped 5.0% coating under visible light was 91.05%.The doping of FRP and the coating of 2.0% S-C₃N₅ cement coating significantly improved the mechanical properties of ordinary concrete.Compared with ordinary concrete，the compressive strength and flexural strength of 28 d curing was increased by 18.97% and 20.00%，respectively.

Key words: FRP filled concrete, nitrogen-rich carbon nitride, photocatalytic cement coating, formaldehyde removal
