Advances in Modification and Applications of Environmental Photocatalysts

Bismuth subcarbonate and graphite carbon nitride(g-C3N4) as novel photocatalysts have been attracted wide attention in recent years. In this review, preparation and modification methods of bismuth subcarbonate and g-C3N4 are systematically introduced. Moreover, non metallic elements doping, heterostructure constructing and metal decorating on the surface are broadly applied in bismuth subcarbonate modification. At the same time, morphological controlling and element doping of g-C3N4 together with g-C3N4 composites are attracted massive studies. Finally, the development of bismuth subcarbonate and g-C3N4 is discussed and opinions on future trend are presented as well.
