“…Numerous photocatalysts have been successfully synthesized, such as titanium dioxide (TiO 2 ), 10 silver oxide, 7 graphitic carbon nitride, 11 bismuth oxide, 12 and copper oxide. 13 Besides, other simple photocatalysts have also been successfully produced, such as phosphorus, boron, sulphur as well as their composites and polymers. 14 In the meantime, photocatalytic membrane technology offers a cost-effective alternative as water treatment, which is composed of a exible way for its usage and shows a powerful capacity of pollutant removal.…”
