- W4285138186 abstract "This chapter discusses hybrid composites, which comprise a carbonaceous matrix material (amorphous carbon, activated carbon, biochar, hydrochar, polymeric carbon, graphene, graphene oxide, reduced graphene oxide, carbon nanotubes, and fullerenes) that serve as a support and/or or anchor of a photocatalyst. Each composite component contributes to the catalytic performance and the mechanism for these good effects is the key point, and these effects can be: Single support effect, stabilization of microstructure or active components, dual function effect on pollutant degradation reactions, influence in the speed of adsorption/desorption and diffusion of molecules, influences the migration or transfer of active free radical species (O2-•, h+, •OH, 1O2), improves mechanics, thermomechanics, electronics or other physical and chemical properties, especially for catalyst polymer matrix composites. Factors such as carbonaceous matrix preparation temperature, origin of this matrix or biomass, pH and synthesis conditions can positively or negatively affect the electron transfer process in the composite, making the composite efficient or not in the degradation of organic pollutants in aqueous media. The application of a carbonaceous matrix in the formation of photocatalytic composites has numerous advantages, as will be seen throughout the chapter. The presence of a carbonaceous matrix facilitates the process of removing the photocatalyst from the medium, facilitates the electron transfer process, requiring less energy to activate the photocatalyst. It is also possible to use carbon from organic waste, such as biomass, reducing the cost of producing composites. These and other advantages will be discussed throughout the chapter, as well as the influence of the synthesis process to obtain a composite with very high photocatalytic efficiency to be applied in the degradation of emerging pollutants." @default.
