TL;DR: In this article, the photocatalytic degradation of phenol, chosen as an aromatic model molecule, has been performed at room temperature (20°C) in contact with a suspended mixture of titania and activated carbon (AC).

TL;DR: In this paper, the photocatalytic degradation of three model pollutants (phenol, 4-chlorophenol, and herbicide 2,4-D) was performed at room temperature in aqueous suspended mixtures of TiO2 and of two different activated carbons (AC) of commercial origin.

TL;DR: A series of activated carbons was prepared from coconut shell impregnated with phosphoric acid using a one-step carbonization procedure and varying conditions in order to optimize preparation parameters as discussed by the authors.

TL;DR: In this article, the authors used ammonium carbonate and nitric acid washing solutions to extract uncombined copper oxide and showed that ammonium-carbonate was only effective for removing dispersed CuO, whereas nitric acids removed both dispersed and crystalline CuO. The results indicated that the active sites are copper species derived from CuAl2O4 and CuCr2O 4 spinels rather than from CuO and indicated that Cu species in tetrahedral coordination lead to higher activity.

TL;DR: The pore size distribution of activated carbon prepared from coconut shell employing different activation methods was investigated in this article, where three simple schemes were proposed depicting the effect of the preparation method on pore sizes distribution.
