Application of 2D Materials to Potassium‐Ion Hybrid Capacitors

Special K: This Review is focused on the latest developments in potassium‐ion hybrid supercapacitors using 2D layered materials, such as graphene, transition metal sulfides/selenides, MXenes, 2D carbon nanosheets, and their composites. The challenges and prospects for the application of 2D layered materials in high‐performance potassium‐ion hybrid supercapacitors...

Co Catalyzed Synthesis of Primary Amines via Reductive Amination employing Hydrogen under very mild Conditions ‐a Nanostructured 3d Metal Catalyst outperforms Noble Metal Catalysts

Nanostructured and reusable 3d‐metal catalysts that operate with high activity and selectivity in important chemical reactions are highly desirable. We report here on a cobalt catalyst for the synthesis of primary amines via reductive amination employing hydrogen as the reducing agent and easy to handle ammonia, dissolved in water, as the nitrogen source....

Facing seawater splitting challenges by regeneration with Ni‐Mo‐Fe OER/HER bifunctional electrocatalyst

Hydrogen, produced by water splitting, has been proposed as one of the main green energy vectors of the future if produced from renewable energy sources. However, to substitute fossil fuels, large amounts of pure water are necessary, scarce in many world regions. In this work, we fabricate efficient and earth‐abundant electrodes, study the challenges...

In‐Depth Comparative Study of Cathode Interfacial Layer for Stable Inverted Perovskite Solar Cell

Achieving long‐term device stability is one of the most challenging issues that impede the commercialization of perovskite solar cells (PSCs). Recent studies have emphasized the significant role of the cathode interfacial layer (CIL) in determining the stability of inverted p‐i‐n PSCs. However, experimental investigations focusing on the influence of...

The Chemical Recycling of Polyesters for a Circular Plastics Economy: Challenges and Emerging Opportunities

Whilst plastics have played an instrumental role in human development, growing environmental concerns has led to increasing public scrutiny and demands for outright bans. This has stimulated considerable research into renewable alternatives, and more recently, the development of alternative waste management strategies. Herein, we aim to highlight recent...

Rationalizing Photo‐Triggered Hydrogen Evolution Using Polypyridine Cobalt Complexes: Substituent Effects on Hexadentate Chelating Ligands

The Cover Feature shows the structure–activity relationship of a family of heptacoordinate CoII complexes for light‐triggered H2 evolution. The complexes present a ligand scaffold including bipyridines and pyridines moieties functionalized with either electron‐donating or electron‐withdrawing groups. Results show that position plays a predominant role...

Ab initio Molecular Dynamics Investigations of the Speciation and Reactivity of Deep Eutectic Electrolytes in Aluminum Batteries

In this work, we study the speciation and reactivity of AlCl3:urea, a deep eutectic solvent (DES) used as electrolyte in Aluminum batteries. Our ab initio molecular dynamics calculations show how the stability of ionic pairs vs. neutral species and the reactivity of the DES increase notably upon increasing the amount of aluminum salt vs. urea in the...

Green Hydrothermal Synthesis of Fluorescent 2,3‐Diarylquinoxalines and Large‐Scale Computational Comparison to Existing Alternatives

The Front Cover shows the synthesis of various quinoxalines in nothing but “hot water”. Aromatic quinoxalines can be synthesized in down to 10 min from the starting compounds in stoichiometric ratio in water at 230 °C through microwave‐assisted hydrothermal synthesis. The synthetic approach is tolerant to a broad array of functional groups and can be...
