Asymmetric Activation of Tropos Biphenolic Moieties by Isohexides: An Integrated Computational‐Experimental Approach

Chemistry – A European Journal, EarlyView.
The integrated experimental‐computational study on the asymmetric activation exerted by isohexides on tropos tetra‐aryl moieties embedded in a chiral macrocyclic architecture resulted in a complete definition of the stereochemical as well as stereodynamic features of the macrocyclic final compounds.

Alkali Metal Mediated Redox Tuning in Bis(μ‐OH) Dinickel(II) Complexes

Chemistry – A European Journal, EarlyView.
Alkali metal ions are ubiquitous in both enzymatic and synthetic catalytic media. The present study highlights the powerful influence common monocations have on the structural and electrochemical properties of catalytically relevant bis(μ‐hydroxo) dinickel diamond cores, through a well‐defined series of heterometallic clusters (Li+, Na+, K+, and Cs ...

Selective Formation of a 1,2‐Diborane(4) and Alcohol‐Driven B─B Bond Cleavage to Generate H2

Chemistry – A European Journal, EarlyView.
Diborane(4) chemistry reveals unusual reactivity of electron‐deficient p‐block compounds. Reaction of B2Cat2 (Cat = benzene‐1,2‐diolate) with mesityllithium (MesLi; Mes = 2,4,6‐trimethylphenyl) gives a rare 1,2‐diborane(4) featuring a catecholate ligand. Alcoholysis cleaves the B─B bond and ultimately generates H2.

Ni–Zn–Ga Alloy for Weak Sunlight‐Driven Methanol Production From CO2 and H2O at Ambient Pressure

EcoEnergy, EarlyView.
The Ni–Zn–Ga ternary alloy‐assisted photothermal CO2 hydrogenation system coupled with photovoltaic water splitting could convert CO2 and H2O into methanol with a production rate of 709 μmol g−1 h−1 under natural sunlight irradiation. ABSTRACT The sunlight‐driven artificial photosynthesis that converts CO2 and H2O into methanol is a promising approach ...

Synergistic Regulation of Hierarchical Anode Interphase and Cathode Electronic Structure by a Fe(III) Complex for High‐Performance Aqueous Zinc‐Manganese Battery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The NGB additive can concurrently address anode and cathode issues during Zn‐Mn battery cycling by constructing a hierarchical interfacial layer on the anode surface to alleviate side reactions and modulate zinc deposition and by incorporating Fe3+ ions into the α‐MnO2 cathode to improve its structural stability and electrical conductivity.

Enhancing the Ferroelectricity of MAPbI3 via Hydroxyl Groups to Boost Photocatalytic Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydroxyl groups in (EOA)2PbBr4 enable a rearrangement of the polar MA+ ions in MAPbI3, which enhances the Ps‐electric field and promotes the separation of photogenerated carriers. Consequently, the (EOA)2PbBr4/MAPbI3 composite exhibits the enhanced CO production yield in photocatalytic CO2 reduction reactions.

Facilitating Hydrogen Evolution Reaction Activity in Alkaline Water Electrolysis via Formation of Ni‐Co2P Heterojunction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ni‐Co2P synthesized via a co‐sputtering method exhibits enhanced hydrogen evolution reaction (HER) activity. The formation of a heterojunction between Ni and Co2P plays a crucial role in this enhancement. At the Ni‐Co2P junction, water dissociation is significantly promoted, while the Ni sites facilitate efficient hydrogen evolution.
