Oxidative ionothermal synthesis for micro and macro Zn-based materials

Abstract

Zn-Based materials produced by direct oxidation of metallic zinc in aqueous [C4C1im]Cl solutions.

High yield and isolation of 2,5-furandicarboxylic acid from HMF and sugars in ionic liquids, a new prospective for the establishment of a scalable and efficient catalytic route

“…The change in morphological structure upon contact of a metal oxide with ionic liquids was further observed in other studies in our group using zinc and it open the prospective for further research on the influence of these solvents on the morphological and chemical structure of the final solid oxide. 28 This observation is consistent with the extensive literature studies with manganese oxide-based catalysts in water where most of the reactions were conducted at catalyst loadings higher than 10 : 1 with respect to HMF, undermining the catalyst recyclability. 13,29,30 Different regeneration methodologies are reported to restore the manganese activity based on the treatment with stoichiometric oxidants at high pH.…”

Exact calculation of corrosion rates by the weight-loss method

“…Some suppliers can provide thin metallic sheets. Some examples include disks of 18 mm diameter and 0.125 mm thickness ( D / h = 144) supplied by Goodfellow Cambridge Limited, which also provide coupons with thickness ranging from 0.0004 to 25 mm (Malaret et al, 2020). Sigma-Aldrich includes foils of 0.001 mm thickness in their catalogue ( s / h = 50,000 for a 50 × 50 mm sheet).…”

Controlling simonkolleite crystallisation via metallic Zn oxidation in a betaine hydrochloride solution

“…Currently, to the best of our knowledge, simonkolleite synthesis routes employing conventional solvents rely on precise pH adjustment to prevent competing reactions (in turn, resulting in the formation of other zinc complexes like Zn(OH) 2 ) 18 . In previous work, an alternative method was developed to produce simonkolleite from zinc using aqueous solutions of 1-butyl-3-methyl-imidazolium chloride 40 . Ionic liquid 1-butyl-3-methyl-imidazolium chloride is employed to catalytically oxidise metal Zn.…”
