dc.description.abstract | We have explored the role of the physicohemical properties of carbon materials as additives to
bismuth tungstate on its structure, optical properties, and photocatalytic activity for the
degradation of rhodamine B under visible light. For this purpose, C/Bi2WO6 hybrid
composites were prepared following two different routes: i) physical mixture of the catalyst
components, and ii) one-pot hydrothermal synthesis of the semiconductor in the presence of
the carbon additive. Three carbons with different properties were selected as additives:
biomass-derived activated carbon, carbon nanotubes and carbon spheres obtained from
polysaccharides. Data has shown the outstanding role of the acidic/basic nature of the carbon
additive, and of the synthetic method on the photocatalytic performance of the resulting
composites. For a given additive, the degradation rate of RhB is greatly improved for the
catalysts prepared through a one-step hydrothermal synthesis, where there is low shielding
effect of the carbon matrix. Carbon additives of acidic nature boost the surface acidity of the
hybrid photocatalyst, thereby enhancing the photodegradation of RhB under visible light via a
coupled mechanism (photosensitization, semiconductor photocatalysis and carbon-photon
mediated reactions). | es |
