Two‐Dimensional Conjugated Benzo[1,2‐b:4,5‐b′]diselenophene‐Based Copolymer Donor Enables Large Open‐Circuit Voltage and High Efficiency in Selenophene‐based Organic Solar Cells

Introduction of two-dimensional conjugated benzo[1,2-b:4,5-b′]diselenophene as a fused electron-rich unit with π-bridging connections into copolymeric donors is an effective strategy for providing high open-circuit voltage and excellent power conversion efficiency (PCE) simultaneously in selenophene-based organic solar cells (OSCs). The optimum PCE...

Bifunctional Janus silica spheres for Pickering interfacial tandem catalysis

Nature provides much inspiration for the design of multistep conversion processes, with numerous reactions running simultaneously and without interference in cells, for example. A key challenge in mimicking nature’s strategies is to compartmentalize incompatible reagents and catalysts, for example, for tandem catalysis. Here, we present a new strategy...

Multisize CoS2 particles intercalated/coated‐montmorillonite as efficient sulfur host for high‐performance lithium sulfur batteries

The chemisorption and catalysis of lithium polysulfides (LiPSs) are effective strategies to suppress the shuttle effect in lithium-sulfur (Li-S) batteries. Herein, multisize CoS 2 particles intercalated/coated-montmorillonite (MMT) as an efficient sulfur host is synthesized. As expected, the obtained S/CoS 2 @MMT cathode achieves an absorption-catalysis...

Electrochemical Reductive Arylation of Nitroarenes with Arylboronic Acids

Reductive arylation: The synthesis of diarylamine is extremely important in organic chemistry. Herein, a novel electrochemical reductive arylation of arylboronic acids with nitroarenes is developed. A variety of diarylamines is synthesized without the need for transition-metal catalysts. The reaction can be scaled up efficiently in a flow cell and several...

Conductivity and Stability Properties of Anion Exchange Membranes: Cation Effect and Backbone Effect

Show some backbone: Poly(vinylbenzyl chloride) (PVB)-based anion exchange membranes (AEMs) show excellent backbone stability, while brominated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO)-based AEMs show higher OH− conductivity and cation stability than those of corresponding PVB-based AEMs. Additionally, heterocycle cation-attached AEMs show relatively...

Engineered Sorghum Bagasse Enables a Sustainable Biorefinery with p‐Hydroxybenzoic Acid‐Based Deep Eutectic Solvent

Mastering sugars: Integrating lignin genetic modification and lignin-based deep eutectic solvents (DESs) enables a sustainable biorefinery. Engineered biomass released high fermentable sugars, and the fractionated lignin could produce DES constituents through hydrothermal treatment. Abstract Integrating multidisciplinary research in plant genetic...

Metal‐Free Triazine‐Based 2D Covalent Organic Framework for Efficient H2 Evolution by Electrochemical Water Splitting

Set HER free: The covalent organic framework C6-TRZ-TFP is synthesized by solvothermal polycondensation of 2-hydroxybenzene-1,3,5-tricarbaldehyde (TFP) and 4,4′,4′′-(1,3,5-triazine-2,4,6-triyl)tris[(1,1′-biphenyl)-4-amine]. C6-TRZ-TFP displays excellent hydrogen evolution activity in electrochemical water splitting with a very low overpotential of 200 mV....

Promoting Electrocatalytic Oxygen Evolution of Ultrasmall NiFe (Hydr)oxide Nanoparticles by Graphene‐Support Effects

Although the activity of electrocatalysts towards oxygen evolution reaction (OER) has achieved considerable improvement by modulating the intrinsic electron structure, the role of supports to OER performance, often being summed to enhancing the conductivity, is not fully explored. In this paper, a proof-of-concept study based on a series of hybrids...
