Integration of membrane filtration and photoelectrocatalysis on g-C3N4/CNTs/Al2O3 membrane with visible-light response for enhanced water treatment

Coupling membrane filtration with photocatalysis provides a promising way to improve the membrane performance for water treatment. However, the quick recombination of photogenerated electron-holes and poor visible-light response limit the performance of photocatalytic membrane. Herein, a g-C3N4/CNTs/Al2O3 membrane was prepared through sequentially coating carbon nanotubes (CNTs) layer with high electroconductivity and g-C3N4 layer with good...
