Synchronous role of coupled adsorption and photocatalytic degradation on CAC–TiO 2 composite generating excellent mineralization of alizarin cyanine green dye in aqueous solution

Adsorptive Removal of Acid Blue 80 Dye from Aqueous Solutions by Cu-TiO2

“…A crucial and primary stage in photocatalytic processes is the adsorption of reacting substances onto the surface of the photocatalysts [16,17]. It is well known that photodegradation of organic molecules is closely related to their adsorption on the photocatalyst surface, thus facilitating electron injection from the adsorbed excited molecules to the photocatalyst [11,18].…”

“…The literature contains many examples of self-dual Leonard pairs. For instance (i) th ated with an irreducible module for the Terwilliger algebra of the hypercube (see [4, Cor Leonard pair of Krawtchouk type (see [10, De nition 6.1]); (iii) the Leonard pair associat module for the Terwilliger algebra of a distance-regular graph that has a spin model in bra (see [1,Theorem], [3,Theorems 4.1, 5.5]); (iv) an appropriately normalized totally (see [11,Lemma 14.8]); (v) the Leonard pair consisting of any two of a modular Leonar De nition 1.4]); (vi) the Leonard pair consisting of a pair of opposite generators for th bra, acting on an evaluation module (see [5,Proposition 9.2]). The example (i) is a spec examples (iii), (iv) are special cases of (v).…”

“…As these compounds are toxic and carcinogenic in nature, therefore, their impact on the environment is a major concern. Furthermore, these dyes impart color to aqueous body blocking the penetration of sunlight and dissolution of oxygen [1][2][3]. Thus, a number of physical and chemical techniques such as filtration, precipitation, coagulation, adsorption and oxidation have been pursued for elimination of these toxic compounds.…”

Copper Oxide Thin Film Synthesis, Characterization and Application as Cathode in Photoelectrocatalytic Cell for Methyl Orange Degradation

“…A number of physical and chemical techniques have been reported for the removal of dye compounds such as adsorption, biodegradation, ozonation, iltration, coagulation and advanced oxidation processes such as Fenton's catalytic reaction and Semiconductor photocatalysts Aggarwal (2016). One of the methods for organic dye waste treatments is using photocatalytic process with semiconductors as catalysts and it has received great attention during the last three decades Aggarwal (2016); Kuriakose et al (2015Kuriakose et al ( , 2017; Muthirulan et al (2017); Sahu, Choudhary, et al (2019); Sahu et al (2018); Singh (2015); Singh, Sahu, et al (2017); .…”
