Merging Biocatalysis and Chemocatalysis in Flow: State‐of‐the‐Art and Future Directions for Sustainable Synthesis

Angewandte Chemie, EarlyView.
This review highlights recent advances in integrating biocatalysis and chemocatalysis in continuous flow to create streamlined, sustainable processes. It examines chemo‐enzymatic cascades combining at least one enzymatic and one chemical step, discusses challenges such as enzyme immobilization, leaching, and reactor clogging, and presents solutions ...

Crystal Structural Determination of SrAlD5 with Corner-Sharing AlD6 Octahedron Chains by X-ray and Neutron Diffraction

Crystals, 2018
Aluminium-based complex hydrides (alanates) composed of metal cation(s) and complex anion(s), [AlH4]− or [AlH6]3− with covalent Al–H bonds, have attracted tremendous attention as hydrogen storage materials since the discovery of the reversible hydrogen ...

Theoretical study of C60 as catalyst for dehydrogenation in LiBH4

, 2011
Complex light metal hydrides possess many properties which make them attractive as a storage medium for hydrogen, but typically, catalysts are required to lower the hydrogen desorption temperature and to facilitate hydrogen uptake in the form of a ...

Reduction of Pyrones with Complex Metal Hydrides [PDF]

Bulletin of the Chemical Society of Japan, 1962
Abstract Reduction using complex metal hydrides was carried out on monocyclic α-pyrones and benzo-γ-pyrone. It was established that generally the hydrogenolysis of the 1,6-linkage of an α-pyrone ring occurred. In benzo-γ-pyrone, carbon-carbon double bond and ketone were reduced.

Orthogonal Design of Competing Deprotonation Process in Cation‐Mediated Ni(OH)2 for Achieving Industrial Level Biomass Electrooxidation

Advanced Science, EarlyView.
A Cu‐mediated Ni(OH)2 catalyst with orthogonal activity by precise valence engineering simultaneously accelerates rate‐determining aldehyde C─H activation in HMF oxidation and impedes O─H deprotonation in competing OER. This multi‐functional synergistic catalysis enables FDCA production at industrial‐level current densities without sacrificing FEFDCA ...

Catalytic Enantioselective Multicomponent Reactions of Sulfoxonium Ylides Enabled by a Formal Rearrangement—A Versatile Entry to Enantioenriched α‐Sulfanyl Carbonyl Compounds

Angewandte Chemie, EarlyView.
A catalytic network embedding a formal rearrangement enables the first catalytic enantioselective multicomponent reaction (MCR) of sulfur ylides. In the presence of a bulky chiral phosphoric acid, the reaction combines sulfoxonium ylides, aldehydes and thiols, and affords synthetically versatile β‐hydroxy‐α‐sulfanyl carbonyl compounds in ...

Hydrogen absorption in metal hydrides: A dual-head tree-based framework for material class classification

International Journal of Thermofluids
Metal hydrides represent a highly promising alternative for hydrogen storage due to their favorable absorption properties and relatively moderate requirements in terms of temperature and pressure during the uptake stage.

Rare Earth Borohydrides—Crystal Structures and Thermal Properties

Energies, 2017
Rare earth (RE) borohydrides have received considerable attention during the past ten years as possible hydrogen storage materials due to their relatively high gravimetric hydrogen density. This review illustrates the rich chemistry, structural diversity

Electrochemically Induced Interphase by Complex Hydride Anions in Argyrodite Solid Electrolytes for Stable Lithium Metal All‐Solid‐State Batteries

Advanced Science, EarlyView.
Complex hydride anion substitution in argyrodite electrolytes has attracted attention for improving interfacial stability, yet the influence of these anions at Li metal interfaces remains unclear. This work shows that electrochemically formed BH4−‐derived interphases enable stable high‐current full‐cell cycling.
