Emerging Potassium‐ion Hybrid Capacitors

A strong building block: Potassium‐ion capacitors holding the merits of the high energy density of potassium‐ion batteries and high output power of supercapacitors are receiving intensive attention owing to the abundant resources and low standard redox potential of potassium. In this Review, the fundamental working principle, recent progress on electrode...

A Carbon Catalyst Co‐Doped with P and N for Efficient and Selective Oxidation of 5‐Hydroxymethylfurfural into 2,5‐Diformylfuran

A new world for carbon: Phosphorus and nitrogen co‐doped carbon (P−C−N) catalyst demonstrates a superb catalytic activity towards selective aerobic oxidation of 5‐hydroxymethylfurfural (HMF) into 2,5‐diformylfuran (DFF). Abstract A newly designed N and P co‐doped carbon material has been developed to catalyze the conversion of 5‐hydroxymethylfurfural...

Molecular Functionalization of NiO Nanocatalyst for Enhanced Water Oxidation by Electronic Structure Engineering

Electronic modulation: A simple molecular modification approach is explored to rationally modulate the electronic structure of NiO nanoparticles, by which the catalyst self‐reconstruction is directly regulated, and the water oxidation activity is systematically tailored. An efficient NiO−C6F5 catalyst is fabricated by the adjusted molecular functionalization...

Surface modification of LiNi0.8Co0.15Al0.05O2 particles via Li3PO4 coating to enable aqueous electrode processing

The successful implementation of an aqueous‐based electrode manufacturing process for nickel‐rich cathode active materials is challenging due to their high water sensitivity. In this work, the surface of LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) was modified with a lithium phosphate coating to investigate its ability to protect the active material...

Fast and Chemoselective Addition of Highly Polarized Lithium Phosphides Generated in Deep Eutectic Solvents to Aldehydes and Epoxides

The Cover Feature shows an unprecedented generation of highly polarized lithium phosphides (LiPR2) through direct selective deprotonation of secondary phosphines (HPR2) in the biodegradable choline chloride/glycerol eutectic mixture, at ambient temperature and under aerobic conditions, and their chemoselective addition to aldehydes or epoxides. More...

Towards Shell Biorefinery: Advances in Chemical‐Catalytic Conversion of Chitin Biomass to Organonitrogen Chemicals

Shelling it: The selective catalytic conversion of chitin biomass to value‐added organonitrogen chemicals is of great significance for effective utilization of bio‐fixed nitrogen in shell waste. Herein, an introduction into recent advances in the production of nitrogen‐containing compounds (typically, amino sugars, amino alcohols, amino acids, and heterocyclic...

Substituent Pattern Effects on the Redox Potentials of Quinone‐Based Active Materials for Aqueous Redox Flow Batteries

A computational screening study has been performed in order to understand and optimize substituent pattern effects of quinone‐based redox‐flow systems. Therefore, the type, number, and position of substituents at benzo‐, naphto‐ and anthraquinione derivatives has been investigated. Abstract Quinone‐based, aqueous redox flow batteries are a promising...

Potential and Buffer Dependent Catalyst Decomposition during Nickel‐based Water Oxidation Catalysis

The production of hydrogen by water electrolysis benefits from the development of water oxidation catalysts. This development process can be aided by the postulation of design rules for catalytic systems. The analysis of the reactivity of molecular complexes can be complicated by their decomposition under catalytic conditions into nanoparticles that...

Building N‐Heterocyclic Carbene into Triazine‐Linked Polymer for Multiple CO2 Utilization

The development of new CO2 detection technology and CO2 "capture‐conversion" material is of great significance due to the growing environmental crisis. Here, we present the multifunctional triazine‐linked polymers with built‐in N‐heterocyclic carbene (NHC) sites (designated as NHC‐triazine@polymer) for simultaneous CO2 detection, capture, activation...

Sustainable Shape‐Memory Polyurethane from Abietic Acid: Superior Mechanical Properties and Shape Recovery with Tunable Transition Temperatures

The persistence of memory: A chemical architecture from abietic acid with a cycloaliphatic unsaturated terminal diisocyanate structure is used to construct an amorphous and biocompatible shape‐memory polyurethane (SMPU) network system with adjustable cross‐linking densities over a wide range. The SMPU network exhibits good shape‐memory properties with...
