VIP: Rational Development of Neutral Aqueous Electrolytes for Zinc–Air Batteries

Simon Clark, Prof. Dr. Arnulf Latz and Dr. Birger Horstmann

Rational Development of Neutral Aqueous Electrolytes for Zinc–Air Batteries

Continuous buffering for power: The first continuum simulation of zinc–air batteries with aqueous ZnCl2–NH4Cl as electrolyte is presented, and the results are compared with two recent experiments. The study derives and implements a novel method for modeling the spatially resolved dynamics of buffered electrolytes.

  1. Imidazolium- and Triazine-Based Porous Organic Polymers for Heterogeneous Catalytic Conversion of CO2 into Cyclic Carbonates

    Hong Zhong, Yanqing Su, Dr. Xingwei Chen, Prof. Xiaoju Li and Prof. Ruihu Wang

    Version of Record online: 22 NOV 2017 | DOI: 10.1002/cssc.201701821

    POP stars: Porous organic polymers (POPs) containing imidazolium and triazine units are presented here. The roles of task-specific components such as triazine, imidazolium, hydroxyl, and counter anions in CO2 absorption and catalytic conversion are illustrated. The catalytic systems show high catalytic activity and excellent recyclability in solvent- and additive-free cycloaddition reaction of CO2 with epoxides.

  2. Reconsidering Water Electrolysis: Producing Hydrogen at Cathodes Together with Selective Oxidation of n-Butylamine at Anodes

    Song Xue, Sebastian Watzele, Dr. Viktor Čolić, Kurt Brandl, Dr. Batyr Garlyyev and Prof. Dr. Aliaksandr S. Bandarenka

    Twice the value: In electrocatalytic water splitting devices, decreasing anodic overpotential and simultaneously changing the anodic reaction to produce valuable chemicals instead of O2 would be a major improvement in overall cost efficiency. Oxyhydroxides of cobalt, nickel/iron, and nickel are industrially relevant electrocatalysts that, as anodes, can selectively catalyze the production of n-butyronitrile from n-butylamine as an easily retrievable valuable product.

  3. Anionic Redox Chemistry in Polysulfide Electrode Materials for Rechargeable Batteries

    Dr. Ekaterina D. Grayfer, Dr. Egor M. Pazhetnov, Dr. Mariia N. Kozlova, Dr. Sofya B. Artemkina and Prof. Vladimir E. Fedorov

    Version of Record online: 22 NOV 2017 | DOI: 10.1002/cssc.201701709

    An-ion of interest: Conventional Li-ion batteries operate through Li insertion/metal redox reactions. However, there is growing evidence that this mechanism is not the only one. Here, we emphasize the role of anion redox reactions in new-generation electrode materials, especially, in transition-metal polysulfides such as trichalcogenides, VS4, FeS2, etc., in which the key role is played by the inline image /S2− transformation.

  4. Imidazolium Ions with an Alcohol Substituent for Enhanced Electrocatalytic Reduction of CO2

    Lin Zhang, Nian Wu, Jichen Zhang, Yang Hu, Dr. Zhiyong Wang, Prof. Lin Zhuang and Prof. Xianbo Jin

    Version of Record online: 22 NOV 2017 | DOI: 10.1002/cssc.201701673

    The secret of the N site: A propanol substituent at the N site of the imidazonium ring can bridge a hydrogen-bonding chain between the C2−H and the O of the CO2, which enables fast proton-hoping transfer, leading to a significant decrease of the activation barrier for the reduction of CO2 to CO in the presence of imidazolium ionic liquids as electrolyte additives with catalytic activity.

  5. Adsorption and Selective Recovery of Citric Acid with Poly(4-vinylpyridine)

    Matthias Van den Bergh, Dr. Ben Van de Voorde and Prof. Dr. Dirk De Vos

    Version of Record online: 22 NOV 2017 | DOI: 10.1002/cssc.201701672

    Citric acid recovery without the sour taste: The conventional method for citric acid recovery after fermentation is not ideal, as not all citric acid can be recovered and the consumption of chemicals, as well as the production of waste, is problematic. The use of a poly(4-vinylpyridine) resin can help overcome these obstacles, rendering the fermentation of citric acid more eco-friendly and economically benign.
