主　　题：high flux nanofibers nanosheet C_(3)N_(4) photocatalytic membrane dye wastewater 

摘      要：Hazardous dye substances discharged from the textile and dyestuff industries not only threaten local the surrounding ecosystems but are also hard to *** report the preparation of process for a photocatalytic membrane device that can degrade dye pollution under visible *** filtration membrane,with a well-organized multilayer structure,simultaneously achieves continuous and flow-through separation of degradation *** nanofibers(CNFs)were used as a template for nanosheet C_(3)N_(4)(NS C_(3)N_(4))preparation;the performance for the photocatalytic degradation of dyes improved as the morphology changed from bulking to *** C3N4 was then attached to the surface of a prepared CNF membrane via vacuum *** device exhibited high efficiency(the degradation rates of both Rhodamine B and Methylene blue both reached 96%),high flux(above 160 L·h^(-1)·m^(-2)·bar^(-1))and excellent stability(maintaining steady flux and high separation were maintained after 4 h).This easy-preparation,easy-scale-up,and low-cost process provides a new method of fabricating photocatalytic membrane devices for dye wastewater treatment.
