Choline chloride–zinc chloride ionic liquid as a green template for the sol–gel synthesis of mesoporous titania

Abstract

Choline chloride–zinc chloride ionic liquid has been used as a green template to synthesis highly crystalline mesoporou anatase titania.

Deep eutectic solvent for spent lithium-ion battery recycling: comparison with inorganic acid leaching

“…Type I DESs of ChCl-2ZnCl 2 were synthesized by Padmapriya et al by mixing ChCl and zinc chloride at a molar ratio of 1 : 1. 59 Then, the mixture was heated to approximately 100 1C at a constant temperature and stirred to obtain a colorless liquid. Azizi 60 mixed ChCl (100 mmol) and SnCl 2 (200 mmol) and heated to 100 1C in air to obtain clear and colorless ChCl-2SnCl 2 DESs.…”

Dyes Depollution of Water Using Porous TiO2-Based Photocatalysts

“…By contrast, the second mechanism labelled the soft templating pathway is less time consuming and more eco-friendly. A large variety of structure-directing agents such as ionic liquid, poly(ethylene glycol), diblock copolymer, polyoxoethylene fluoroalkyl ether, cyclodextrins or home-made block copolymers (BCPs) have been used to prepare the porous titania material though the soft templating route (Zimny et al 2010;Veliscek-Carolan et al 2015;Lannoy et al 2014;Cao et al 2016;Preethi et al 2017). Nevertheless, among these templates, thanks to their large molecular weights, the triblock copolymers such as Pluronic P123 or F127 are the most widely considered for the preparation of porous TiO2 (Ismail and Bahnemann 2011).…”

Influence of crystallization conditions and of gaseous ammonia treatment on mesoporous TiO2 properties

“…Comparing with the hard templating mechanism, for which the titania materials is obtained via the replication of a mould such as ordered mesoporous silica, the soft templating pathway is less time consuming and more eco-friendly since it does not require hydrofluoric acid to remove the hard template. A large variety of structure-directing agents such as ionic liquid, poly(ethylene glycol), diblock copolymer, polyoxoethylene fluoroalkyl ether, cyclodextrins or home-made block copolymers (BCPs) have been used to prepare the porous titania material though the soft templating route [18][19][20][21][22][23][24]. Nevertheless, among these templates, thanks to their large molecular weights, the triblock copolymers such as Pluronic P123 or F127 are the most widely considered for the preparation of porous TiO 2 [17,25,26].…”
