TL;DR: The photocatalytic activities of prepared catalysts were evaluated using the degradation of aqueous methylene blue solution as a model compound under visible light irradiation and results suggested that the prepared CeO 2/V2O5 and CeO2/CuO nanocomposites can generate more electrons and holes under visibleLight irradiation.

TL;DR: In this paper, mass transfer kinetic approach has been successfully applied for the determination of various parameters necessary for designing a fixed-bed absorber, such as the length of the (PAZ) primary adsorption zone, total time involved for the establishment of primary adaption zone (tx), mass rate of flow to the absorber (Fm), time for primary adsoration zone to move down its length (tδ), amount of adsorbate adsorbed in PAZ from breakpoint to exhaustion (Ms), fractional capacity (f), time of initial

TL;DR: Vinod K. Gupta is a Professor of physical chemistry at King Fahd University of Petroleum and Minerals, Dhahran, Saudi Arabia and recipient of the Indian Citation Laureate Award 2004.

TL;DR: The outcomes support the feasibility of preparing high quality activated carbon from waste rubber tire by microwave assisted chemical activation and physical heating respectively.

TL;DR: It is found that under the influence of TiO2 as catalyst the colored solution of the dye Safranin-T becomes colorless and the process follows first-order reaction kinetics, which implies that the photodegradation throughTiO2 is a safer technique.
