Visible-light-active Fe-POMs was fabricated via precipitating Fe3+with Keggin type polyoxometalates(H3PW12O40,H4SiW12O40 or H3PMo12O40)under solvothermal condit
The Ag+photoreduction by graphitic carbon nitride(g-CN)materials in a high concentration of Ag+solution is reported,and a series of colorful Ag/g-CN composites
Due to the quite sluggish charge-carrier separation in semiconductor photocatalysts,the photocatalytic ac-tivity of these materials is still far inferior than a
