摘      要：An efficient photo-Fenton catalyst(Fe S_(2)@HTCN)was designed by maximizing the synergistic effect of Fe S_(2)nanoparticles and hollow tubular g-C_(3)N_(4)(HTCN).Molecule self-assembly and molten salts-assisted calcination were used to engineering the hollow structured g-C_(3)N_(4)before anchoring Fe S_(2)nanoparticles on the walls of HTCN via reflux *** to bulk g-C_(3)N_(4),the unique structure of HTCN and heterojunction in the composite endowed FeS_(2)@HTCN with more active sites and abundant channels for electron transfer and charge *** enriched electrons can improve the Fe^(3+) recycling and boost Fe^(2+) catalyzed ^(·)OH production via H_(2)O_(2).As-prepared photo-Fenton catalyst was successfully applied to the treatment of industrial paint *** paint wastewater with its COD as high as 8200 mg/L can be effectively degraded with 0.2 mol/L H_(2)O_(2)in 90 min under visible light *** photoFenton system was further evaluated according to the process stability and economic benefit,proving that the strategy presented in this work would be applicable to the treatment of real wastewater.
