Photocatalytic technology has received substantially attention as it can make use of solar energy for wastewater degradation.Particularly,the cost,degradation performance and lifetime of photocatalyst are significant reference during the actual application.Nevertheless,traditional photocatalyst,such as anatase TiO_2,can only absorb the UV part(about 5%)of the total solar spectrum,restricting its industrial application.Owing to their availability,low cost and superior visible-light absorption,metal sulfides ...
