An ionic liquid-triazine and KI combination was found to be an efficient catalyst for epoxide cyclic carbonate conversion under CO<sub>2</sub> filled balloon conditions.
Abstract The development of MoS 2 in the metallic phase (1T‐MoS ) is paramount interest as it exhibits superior electrochemical activities compared to its semiconducting polymorph (2H‐MoS ). In this work, an ionic liquid (IL)‐assisted solvothermal method was employed produce thermodynamically metastable 1T‐MoS . Structural characterization material suggests intercalation IL into De‐intercalation ILs from leads formation 2H‐MoS Carbon cloth‐supported @CC) shows higher electrocatalytic...

Abstract In this work we have achieved epoxide to cyclic carbonate conversion using a metal‐free polymeric catalyst under ambient CO 2 pressure (1.02 atm) balloon setup. The triazine containing polymer (CYA‐ANIS) was prepared from cyanuric chloride (CYA−Cl) and o‐dianisidine (ANIS) in anhydrous DMF as solvent by refluxing the N gas environment. presence of amine functional groups results adsorption up 7 cc/g at 273 K. This inspired us utilize for series functionalised epoxides into their...

An efficient fixation of CO 2 into epoxide is achieved by using a halide free aluminium-based polymeric material as catalysts under atmospheric pressure.
Utilization of carbon dioxide by converting it into value-added chemicals is a sustainable remedy approach that stipulates abundant, cheap, non-toxic and efficient catalytic materials. In this study, we have demonstrated the use para-aminobenzoic acid-capped hematite (PABA@α-Fe2O3) as an nanocatalyst for conversion epoxides to cyclic carbonates utilizing CO2. The developed PABA@α-Fe2O3 along with cocatalyst, tetrabutylammonium iodide (TBAI), was able convert variety epoxide substrates their...

Excellent activity of cobalt oxides/hydroxides towards electrocatalytic oxygen evolution reaction (OER) demands the development a unified protocol to synthesize different phases these materials. In this paper, low-temperature (120 °C) solvothermal method was developed pure phase Co3O4, Co2(OH)3Cl, and CoII1–xCoIIIx(OH)2Clx·nH2O [HT(II,III)] detailed analyses their formation mechanism, intrinsic as well geometric toward OER electrocatalysis, were carried out. This employs variety amines...
Abstract The rising global warming and associated climate change demand efficient tactics to reduce CO 2 concentration in the atmosphere. Conversion of epoxides cyclic carbonates utilizing is a promising sustainable approach towards fixation. However, inert nature high activation energy requirement for particular reaction necessitate use catalysts. In this work, we have designed developed heterogeneous catalyst using catechol functionalized guanidinium based ligands (L1) Fe(III) ions perform...
