Pectin/graphene oxide aerogel with bamboo-like structure for enhanced dyes adsorption

Stepwise rapid electrolytic synthesis of graphene oxide for efficient adsorption of organic pollutants

“…For example, GO can form stable dispersions in water, in which the rich oxygen functional groups contribute to high-performance adsorbents, 5,6 hydrogels 7,8 and aerogels. 9,10 Moreover, GO generally shows good electrical conductivity after reduction, making it suitable for supercapacitors, 11,12 and fuel cells. 13,14 Additionally, the feasibility of surface modification makes GO a great platform for preparing a variety of composite materials.…”

A transparent and robust ionogel prepared via phase separation for sensitive strain sensing

“…The simulation process involved geometric optimization, followed by annealing for 25 cycles at 600 K. Lastly, a dynamic simulation was conducted for 1 ps to obtain the final equilibrium structure of the ionogels. 25 The resulting structure of the ionogel at its equilibrium state is shown in Fig. 2c and S2 †.…”

Selective Adsorption of Methyl Orange and Methylene Blue by Porous Carbon Material Prepared From Potassium Citrate

“…Adsorption isotherms are mainly used to analyze the adsorption behaviors between the adsorbent and the adsorbate. Many adsorption isotherms have been proposed from different perspectives; the commonly used models include the Langmuir adsorption isotherm model, the Freundlich adsorption isotherm model, and the Temkin adsorption isotherm model. ,,,− The Langmuir isotherm is on account of the monolayer adsorption theory; that is, there are a certain number of adsorption sites on the adsorbent surface, and each site can adsorb a molecule, so the surface adsorption is a monolayer. The formula is as follows: c normale q normale = 1 q m K L + 1 q normalm c e where q m (mg g –1 ) is the Langmuir monolayer adsorption capacity and K L (L mg –1 ) is the Langmuir adsorption constant.…”
