Themed collection 3rd International Symposium on Green Chemistry

This Perspective discusses target parameters for the electroreduction of CO₂, based on its comparison with water splitting, which is to become a practical alternative for energy storage into fuels and chemicals.

There is very strong opinion that Green Analytical Chemistry is needed beside so-called common Analytical Chemistry. However, the developments in Analytical Chemistry must lead to environmentally safe, economical and cost-effective methods on the whole.

Milk is a natural suspension of essential nutrients and can be exploited not only as a beverage consumed directly or transformed into a range of traditional dairy foods, for food and non-food product innovation and environmental benefits.

Here we report that γ-valerolactone (GVL), a biomass-derived solvent, can be used to facilitate the mild pretreatment of lignocellulosic biomass.

The influence of physicochemical cellulose parameters and cellulose purity on the heterogeneous hydrolytic hydrogenation of (ligno)cellulose to hexitols.

Experimental and theoretical approaches are combined for optimizing Ru catalysts for hydrogenation of levulinic acid (LA) with formic acid (FA) as a hydrogen source into γ-valerolactone (GVL). Particle size and influence of Ru precursor are considered as crucial parameters.

LCA of the synthesis of curcumin and its direct conventional and microwave assisted extractions from Curcuma longa L. were compared.

All-vanadium dual circuit redox flow battery capable of converting surplus electricity into hydrogen and performing simultaneous desulfurization with high efficiency.

The hydrogen transfer initiated dehydration of 1,3-propanadiol to propionaldehyde, catalysed by a highly recyclable, air and water stable, soluble Ir(III) complex, in an ionic liquid, was demonstrated.

A multi-criteria approach based on life cycle thinking is proposed to investigate the production of 1,3-butadiene.

Iron-containing N-doped carbon materials are active electrocatalysts for the cogeneration of hydroxylamine and electricity in a H₂–NO fuel cell, which is a promising alternative to the present industrial synthesis.

Quantum calculations show that βO4′ links break in two ways; the carbanion route yields monomers, the alkoxide route facilitates repolymerisation.

In MgO–SiO₂ catalysts for the transformation of bio-ethanol into butadiene, the generation of more selective sites is achieved by the dispersion of isolated Si⁴⁺ atoms in MgO.

The concomitant deactivation mechanisms of tin-containing zeolites applied in the isomerisation of dihydroxyacetone and xylose were unravelled and the main synthetic and operational parameters toward stable operation uncovered.

A magnetic Co-based heterogeneous catalyst derived from MOFs is highly efficient in selective oxidation of alcohols in neat water under an atmospheric pressure of air and base-free conditions.

The hydrothermal carbonization process can be considered as a source for valuable apolar platform molecules derived from certain lignocellulosic biomass waste feedstocks in addition to the production of hydrochar.

Ferrospinels of the general composition Co_0.6−xMn_xFe_2.4O_y were studied as O²⁻ and electron vectors for the chemical-loop reforming of ethanol aimed at the production of clean H₂.

Bio-based epoxy thermosets with good thermo-mechanical properties were prepared from model mixtures of products from the lignin-to-vanillin process.

n-Pentane (yield 70%), pentanols (32%) or xylitol (79%) can be produced from xylan by using an Ir–ReO_x/SiO₂ catalyst combined with acids.

The selective oxidation of complex, water-insoluble and wet biomass from second and third generation to formic acid including effective catalyst recycling is reported. Additionally, the relevance and limits of potential contaminants are illustrated by different experimental approaches.

Different metal acetate salts were systematically examined for the catalytic deoxygenation of stearic acid in the absence of H₂ and solvent for the first time.
