title: Photocatalytic activities of coke carbon/g-C3N4and Bi metal/Bi mixed oxides/g-C3N4nanohybrids for the degradation of pollutants in wastewater.
abstract: Different g-C3N4composite systems (coke carbon/g-C3N4, Bi/Bi2WO6/g-C3N4and Bi/Bi2MoO6/g-C3N4) have been assessed as photocatalysts for wastewater pollutants removal. The coke carbon/g-C3N4hybrid, produced by thermal treatment at 550 °C of a composite made from melamine cyanurate and coke, only showed activity under UV-light irradiation. On the other hand, inorganic Bi spheres/Bi mixed oxides/g-C3N4nanohybrids (Bi/Bi2WO6/g-C3N4and Bi/Bi2MoO6/g-C3N4composites), produced by thermal reduction of Bi2WO6or Bi2MoO6by g-C3N4, exhibited a remarkable red-shift, up to 620 nm, and allowed the visible-light driven degradation of the contaminant, albeit in combination with some adsorption.
