Towards sustainable fuels and chemicals through the electrochemical reduction of CO2: lessons from water electrolysis
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.
Do we need Green Analytical Chemistry?
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.
Retracted Article: Bigger data open innovation: potential applications of value-added products from milk and sustainable valorization of by-products from the dairy industry
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.
A mild biomass pretreatment using γ-valerolactone for concentrated sugar production
Here we report that γ-valerolactone (GVL), a biomass-derived solvent, can be used to facilitate the mild pretreatment of lignocellulosic biomass.
The importance of pretreatment and feedstock purity in the reductive splitting of (ligno)cellulose by metal supported USY zeolite
The influence of physicochemical cellulose parameters and cellulose purity on the heterogeneous hydrolytic hydrogenation of (ligno)cellulose to hexitols.
Ru catalysts for levulinic acid hydrogenation with formic acid as a hydrogen source
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.
Phytochemical compounds or their synthetic counterparts? A detailed comparison of the quantitative environmental assessment for the synthesis and extraction of curcumin
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 for renewable hydrogen generation and desulfurisation
All-vanadium dual circuit redox flow battery capable of converting surplus electricity into hydrogen and performing simultaneous desulfurization with high efficiency.
Combining bio- and chemo-catalysis for the conversion of bio-renewable alcohols: homogeneous iridium catalysed hydrogen transfer initiated dehydration of 1,3-propanediol to aldehydes
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.
Butadiene from biomass, a life cycle perspective to address sustainability in the chemical industry
A multi-criteria approach based on life cycle thinking is proposed to investigate the production of 1,3-butadiene.
Iron-containing N-doped carbon electrocatalysts for the cogeneration of hydroxylamine and electricity in a H2–NO fuel cell
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.
Intermediate oxiranes in the base-catalyzed depolymerisation of lignin
Quantum calculations show that βO4′ links break in two ways; the carbanion route yields monomers, the alkoxide route facilitates repolymerisation.
An analysis of the chemical, physical and reactivity features of MgO–SiO2 catalysts for butadiene synthesis with the Lebedev process
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.
Deactivation mechanisms of tin-zeolites in biomass conversions
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.
Efficient and selective aerobic oxidation of alcohols catalysed by MOF-derived Co catalysts
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.
Fuel and chemicals from wet lignocellulosic biomass waste streams by hydrothermal carbonization
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.
Towards an improved process for hydrogen production: the chemical-loop reforming of ethanol
Ferrospinels of the general composition Co0.6−xMnxFe2.4Oy were studied as O2− and electron vectors for the chemical-loop reforming of ethanol aimed at the production of clean H2.
Epoxy thermosets from model mixtures of the lignin-to-vanillin process
Bio-based epoxy thermosets with good thermo-mechanical properties were prepared from model mixtures of products from the lignin-to-vanillin process.
Selective transformation of hemicellulose (xylan) into n-pentane, pentanols or xylitol over a rhenium-modified iridium catalyst combined with acids
n-Pentane (yield 70%), pentanols (32%) or xylitol (79%) can be produced from xylan by using an Ir–ReOx/SiO2 catalyst combined with acids.
Expanding the scope of biogenic substrates for the selective production of formic acid from water-insoluble and wet waste biomass
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.
Effective deoxygenation of fatty acids over Ni(OAc)2 in the absence of H2 and solvent
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.
