Pd‐Promoted General Synthesis of Aurones Using CO2

The carbonylation of alkynes using CO2 to generate aurones is unknown. Here, we report palladium-catalyzed carbonylation of terminal aromatic alkynes and the waste hydrosilane, poly(methylhydrosiloxane) (PMHS) with 2-iodophenol using CO2 to produce aurones. A variety of terminal alkynes and the substituted 2-iodophenols are transformed into aurones...

Cobalt Nanoparticles Anchored on N‐Doped Porous Carbon Derived from Yeast for Enhanced Electrocatalytic Oxygen Reduction Reaction

Beauty and the yeast: N-doped porous carbon electrocatalyst is synthesized by the activation and pyrolysis of yeast. Additional Co-based active sites are introduced into the porous structure by exploiting the strong interaction between activated yeast and Co–Phen complex. The obtained composite CoNC electrocatalyst demonstrates significantly enhanced...

TM2−B2 Quadruple Active Sites Supported on a Defective C3N Monolayer as Catalyst for the Electrochemical CO2 Reduction: A Theoretical Perspective

Choose carefully: Transition metal (TM2)−B2 quadruple active sites supported on a defective C3N monolayer are explored as effective electrocatalysts for the CO2 reduction reaction by means of density functional theory calculations. The selectivity towards C1 or C2+ products depends on the adsorption strength of either C or O atoms. This dependence can...

Self‐Activation of Inorganic‐Organic Hybrids Derived through Continuous Synthesis of Polyoxomolybdate and para‐Phenylenediamine Enables Very High Lithium‐Ion Storage Capacity

Inorganic-organic hybrid materials with redox-active inorganic and organic components are prepared by a continuous wet chemical synthesis method. They represent a new class of electrode materials for lithium-ion batteries. These materials can be synthesized in the so-called microjet reactor by an efficient, scalable precipitation reaction at room temperature...

One‐Pot Tandem Transformation of Inulin as Fructose‐Rich Platform Towards 5‐Hydroxymethylfurfural: Feedstock Advantages, Acid‐Site Regulation and Solvent Effects

Inulin Valorization: Inulin can serve as a non-grain fructose-rich platform for broader participation in the construction of a sustainable biomass-derived chemical supply system. In this Review, feedstock advantages, acid-site regulation approaches and solvent effects of the one-pot tandem transformation of inulin towards 5-hydroxymethylfurfural are...

Novel Strategy for the Formulation of High‐Energy‐Density Cathodes via Porous Carbon for Li‐S Batteries

Get in the C: A micro-scale active material is prepared by infiltrating sulfur into porous carbon material, and by combining carbon nanotubes and carbon black to increase sulfur content. The active material is incorporated into a lithium−sulfur battery with high-energy and enhanced electron conductivity. Abstract Porous carbon is considered an...

Spreading the Landscape of Dual Ion Batteries: from Electrode to Electrolyte

The Front Cover shows the working mechanism of dual-ion batteries (DIBs). That is, the positive ions in the electrolyte move and embed into the anode during charging, while the negative ions in the electrolyte move and embed into the cathode, whereas it is the processes are reversed for the discharging process. Such a battery has two types of ions that...

Rational Design of Functional Electrolytes Towards Commercial Dual‐Ion Batteries

The Cover Feature shows a dual-ion battery based on anion intercalation into graphite cathode for grid-scale energy storage. Electrolytes providing both cations and anions for battery reactions serve as active materials and thus need to meet stringent requirements including high oxidation stability, high concentration, high ionic conductivity and low...

Organic Cathode Materials for Rechargeable Aluminum‐Ion Batteries

Organic electrode materials (OEMs) have shown enormous potential in ion batteries because of their varied structural-components and adaptable construction. As a brand-new energy storage device, rechargeable aluminum batteries (RABs) have also received a lot of attention due to their high safety and low cost. OEMs are expected to stand out among many...

Basal Plane‐Activated Boron‐Doped MoS2 Nanosheets for Efficient Electrochemical Ammonia Synthesis

Basal plane-activated B-doped MoS2 nanosheets as a non-noble metal catalyst with excellent performance for N2 electroreduction are synthesized by a facile one-step hydrothermal method. MoS2 nanosheets doped with 300 mg boric acid (B−MoS2-300) give rise to a good ammonia yield rate of 75.77 μg h−1 mg−1 cat. at −0.75 V vs. RHE, and an excellent Faradaic...
