TL;DR: In this article, different liquid phase thermal treatments were applied to a commercial activated carbon (Norit ROX 0.8) in order to produce modified activated carbons with varying surface chemistry and increased acidic character.

TL;DR: In this article, chemically functionalized multi-walled carbon nanotubes (CNTs) are used as carriers for laccase immobilization and recovered activity were evaluated using 2,2′-azino-bis(3-ethylbenzathiazoline-6-sulfonic acid) biocatalytic oxidation.

TL;DR: In this article, metal-free exfoliated graphitic carbon nitride (gCNT) was used as photocatalyst for the degradation of organic micropollutants (MPs) found in the biologically treated effluents of an urban wastewater treatment plant (UWWTP).

TL;DR: In this article, the photocatalytic degradation of the psychoactive substance caffeine was studied using composites prepared with multi-walled carbon nanotubes and three different TiO2 materials: one synthesized by a modified sol-gel method and two others obtained from Evonik and Sigma-Aldrich.

TL;DR: In this paper, the photocatalyst made of ZnO prepared by thermal decomposition of zinc acetate (ZnO-t) loaded with a 025 atomic percentage of Ag (025%Ag/ZnOsO-T) was the most efficient, reaching a 58% mineralization after 60min irradiation.
