Adsorption of Rhodamine B and methyl orange on a hypercrosslinked polymeric adsorbent in aqueous solution

Hybrid nanocomposites with enhanced visible light photocatalytic ability for next generation of clean energy systems

“…Such hypothesis is supported also by previous studies that have showed that the reaction rate constant for rhodamine B is around .0058 min -1 on a hypercrosslinked polymeric adsorbent in aqueous solution, which is almost the double compared to .0028 min -1 for methyl orange. [61,62,102] Although a direct comparison between these studies [61][62][63][64] is rather difficult because of the differences in the working conditions and sample preparation, it is evident that optimum usertailored properties and sample characteristics will largely influence the ability to photodegrade any of the proposed tested dye.…”

“…[59] Further, the focus on rhodamine B is also supported by previous studies that showed that the dye is an active carcinogen, [60] more difficult to remove than other dyes such as methyl orange or methylene blue. [61][62][63][64] Our research aims to unravel the fundamental mechanisms, properties and processes that allow for increased performance, reliability, competitiveness and implementation of WO3-GO heterostructures in robust architectures while preserving their performance, all under visible light.…”

Soft-template assisted synthesis of mesoporous CuO/Cu 2 O composite hollow microspheres as efficient visible-light photocatalyst

“…Firstly, due to its high visible light absorption capability and porous shell structure, both visible light and MO moleculars are more conveniently penetrated into it with the significantly accelerated diffusion velocity and reaction rate. For instance, the molecular size of MO is 1.19 nm  0.67 nm  0.38 nm [21], leading to the easy entrance and diffusion of MO molecules into the pores of catalyst (pore size: 4.0-100 nm). Secondly, its unique micro-sized hollow structure can also provide high throughput hollow reaction regions, not only enhancing the light harvesting and scattering, but also facilitating the transfer and diffusion of dye molecules [5].…”

A novel reusable nanocomposite: FeOOH/CBC and its adsorptive property for methyl orange

“…Chemical oxidation [2,3], membrane filtration [4], magnetic separation [5], coagulation [6,7], biodegradation [8], photocatalysis degradation [9][10][11] and adsorption [12,13] are most widely used for removing dyes from effluents. Among the numerous techniques of dye removal, adsorption is one of the most attractive methods due to its high effectiveness, economy, operational simplicity and low energy consumption [14][15][16][17]. Furthermore, organic dyes can be concentrated after they are adsorbed, which provides a good foundation for their reuse.…”
