VIP: Aqueous Biphasic Systems for the Synthesis of Formates by Catalytic CO2 Hydrogenation: Integrated Reaction and Catalyst Separation for CO2-Scrubbing Solutions

Aqueous Biphasic Systems for the Synthesis of Formates by Catalytic CO2 Hydrogenation: Integrated Reaction and Catalyst Separation for CO2-Scrubbing Solutions

Scrubs up well: An integrated process for the synthesis of formate–amine adducts based on aqueous biphasic catalysis is presented. The solvent pair methyl isobutyl carbinol (MIBC)/water led to the most productive system with a ruthenium complex as catalyst. Re-use of the catalyst phase was demonstrated. This approach enables the direct hydrogenation of carbon dioxide in aqueous solutions of monoethanolamine and methyl diethanolamine, as used in carbon capture technologies, with a total turnover number of up to 150 000.

High Redox Capacity of Al-Doped La1−xSrxMnO3−δ Perovskites for Splitting CO2 and H2O at Mn-Enriched Surfaces

The big split-up: Upon Al doping of lanthanum–strontium manganites, manganese enrichment and strontium depletion is observed at the perovskite surface. This is correlated with a higher redox activity and lower carbonate formation, both beneficial for CO2-splitting applications.

VIP: Carbon-Nanodot Solar Cells from Renewable Precursors

Dr. Adam Marinovic, Lim S. Kiat, Prof. Steve Dunn, Prof. Maria-Magdalena Titirici and Dr. Joe Briscoe

Carbon-Nanodot Solar Cells from Renewable Precursors

Biomaterials-to-nanomaterials for solar energy: Carbon nanodots synthesised by hydrothermal method from a wide range of biomaterials are used as sensitisers for TiO2-based nanostructured solar cells, and their performance is analysed and compared. l-arginine carbon nanodots used as sensitisers show the highest solar power conversion efficiency (PCE) of 0.36 %, whereas carbon nanodots from lobster shells show a PCE of 0.22 %.

Synthesis of Butyl Levulinate Based on α-Angelica Lactone in the Presence of Easily Separable Heteropoly Acid Catalysts

Switchable solubility: A series of heteropoly acid compounds ChxH(6−x)P2W18O62 with temperature-dependent solubility allows an efficient butyl levulinate formation from α-angelica lactone and an alcohol under mild conditions, thus avoiding any byproducts. The catalyst is easily separable and can be reused five times without significant loss of activity.

Synthesis of Cobalt Phosphide Nanoparticles Supported on Pristine Graphene by Dynamically Self-Assembled Graphene Quantum Dots for Hydrogen Evolution

CoProducing H2: Small, uniform, high-density, and well-dispersed CoP nanoparticles (NPs) were grown in situ on pristine graphene for the first time by dynamically self-assembled graphene quantum dots (GQDs)-mediated synthesis, showing a very high catalytic activity and excellent durability toward the hydrogen evolution reaction.

Anodic Behavior of the Aluminum Current Collector in Imide-Based Electrolytes: Influence of Solvent, Operating Temperature, and Native Oxide-Layer Thickness

Al-l that dissolves: A study on the dissolution of aluminum current collectors in imide-based electrolytes in lithium-ion batteries is presented. The influence of the solvent, operating temperature, and thickness of the native oxide layer is discussed and a mechanism for the anodic dissolution of aluminum is proposed.

Selective Hydrogenation of Nitriles to Primary Amines by using a Cobalt Phosphine Catalyst

Cobalt catalyzes it: A general procedure for the selective hydrogenation of (hetero)aromatic or aliphatic nitriles catalyzed by a cobalt-based system is described. A wide range of primary amines are synthesized in 61–99 % yield. Use of the tetradentate ligand tris[2-(dicyclohexylphosphino)ethyl]phosphine is key for the activity of the system.

Direct Synthesis of Renewable Dodecanol and Dodecane with Methyl Isobutyl Ketone over Dual-Bed Catalyst Systems

Dual-bed catalysis: For the first time, dodecanol and jet fuel range C12-branched alkane (2,4,8-trimethylnonane) are directly synthesized with high carbon yield (∼70 %) by using dual-bed catalyst systems with hydrogen and methyl isobutyl ketone (MIBK) that can be derived from lignocellulose.
