    1. Crucial Role of Donor Density in the Performance of Oxynitride Perovskite LaTiO2N for Photocatalytic Water Oxidation

      Version of Record online: 17 FEB 2017 | DOI: 10.1002/cssc.201601602

      Improving photocatalysts: Sufficient donor density in LaTiO2N photocatalysts is essential to generate an efficient internal electric field for charge separation and for high oxidizing power of the holes. On the basis of this understanding, LaTiO2N photocatalysts were modified to give a quantum efficiency for water oxidation of 25 % at 450 nm, which is higher than that of conventional LaTiO2N.

    1. Low-Energy Catalytic Electrolysis for Simultaneous Hydrogen Evolution and Lignin Depolymerization

      Xu Du, Wei Liu, Zhe Zhang, Arie Mulyadi, Alex Brittain, Prof. Jian Gong and Prof. Yulin Deng

      Version of Record online: 17 FEB 2017 | DOI: 10.1002/cssc.201601685

      Two birds with one stone: A new direct lignin proton-exchange-membrane electrolysis can significantly reduce the electrolysis energy consumption in hydrogen production and, simultaneously, depolymerize lignin to value-added aromatic chemicals. Lignin is used as the aromatics and hydrogen source at the anode. Either polyoxometalate or FeCl3 is used as the catalyst and charge-transfer agent at the anode.

      Scrubs up well: An integrated process for the synthesis of formate–amine adducts based on aqueous biphasic catalysis is presented. The solvent pair methyl isobutyl carbinol (MIBC)/water led to the most productive system with a ruthenium complex as catalyst. Re-use of the catalyst phase was demonstrated. This approach enables the direct hydrogenation of carbon dioxide in aqueous solutions of monoethanolamine and methyl diethanolamine, as used in carbon capture technologies, with a total turnover number of up to 150 000.

      The Inside Cover picture shows a gold nanowire electrode (top), and a coaxial nanowire electrode with nanowires that have a gold core and a polypyrrole shell (bottom). The coaxial nanowire electrode has the ability to store a large amount of energy through the pseudocapacitance of the outer polypyrrole layer, and charge can be transferred to the inner gold core at fast rates, making it ideal for use in pseudocapacitors. This coaxial structure is effective at reducing the internal resistance of the electrode and the energy density is increased without a noticeable deterioration of power density.

      The Planktonic Relationship Between Fluid-Like Electrodes and Bacteria: Wiring in Motion

      Dr. Sara Tejedor-Sanz, Jose Rodrigo Quejigo, Dr. Antonio Berná and Prof. Abraham Esteve-Núñez

      Version of Record online: 16 FEB 2017 | DOI: 10.1002/cssc.201700219

      Thumbnail image of graphical abstract

      The Cover picture shows the bacteria-electrode interaction between a fluid-like electrode and planktonic living cells in a microbial electrochemical device. We show for the first time that a biofilm living mode is not a strict requirement for Geobacter sulfurreducens to perform extracellular electron transfer (EET) to an anode, an alternative to the paradigm of microbial EET in which electroactive bacteria colonize an electrically conductive surface to transfer electrons directly to it. More details can be found in the Full Paper by Tejedor-Sanz et al. (DOI: 10.1002/cssc.201601329).

    1. On the Structure–Property Relationships of Cation-Exchanged ZK-5 Zeolites for CO2 Adsorption

      Version of Record online: 16 FEB 2017 | DOI: 10.1002/cssc.201601648

      Thumbnail image of graphical abstract

      Identifying CO2 adsorption sites: A Rietveld refinement of a synchrotron powder X-ray diffraction pattern of CO2 dosed on Na-ZK-5 zeolite is used to determine the locations of adsorbed CO2 molecules. Three adsorption sites for CO2 are found: Site A is situated in the middle of the flat eight-membered ring windows, site B/B*, described as dual-cation adsorption sites to two Na+(II) cations, is the dominant site, and CO2 adsorption at site C can be considered as single or dual Na+ cation site in the α-cages.

    2. Solvothermally-Prepared Cu2O Electrocatalysts for CO2 Reduction with Tunable Selectivity by the Introduction of p-Block Elements

      Version of Record online: 16 FEB 2017 | DOI: 10.1002/cssc.201601578

      Thumbnail image of graphical abstract

      One way or another: The selectivity towards CO2 reduction over Cu2O electrocatalysts prepared by a simple and potentially scalable solvothermal route can be tuned by the introduction of p-block elements. The addition of Sn and In enhances the selectivity for CO, whereas the introduction of Al promotes the formation of valuable C2 and C3 products at moderate overpotentials.

      Easy transport: A polymeric membrane-supported gold nanoparticle (AuNP) catalyst is prepared on the basis of the extraction and in situ reduction of AuIII in one stage achieved by a facilitated transport system. This process is a synergic phenomenon in which all the membrane components are involved. The catalysts allow 95.4 % reduction of 4-nitrophenol in aqueous solution in 25 min and provides catalysis and separation in the same stage.

      A closer look at lignin structures: New insights are gained from authenticating and quantifying dimeric thioacidolysis products using various synthesized standard guaiacyl-type dimers. A longstanding compound assignment error is corrected, the dilemma of observing no β–β products from pinoresinol structures from softwood lignins is resolved, and the combinatorial nature of lignification is confirmed.

      The big split-up: Upon Al doping of lanthanum–strontium manganites, manganese enrichment and strontium depletion is observed at the perovskite surface. This is correlated with a higher redox activity and lower carbonate formation, both beneficial for CO2-splitting applications.

      Thumbnail image of graphical abstract

      Ions in the deep: The total amount of ions in an electrolyte solution in a lithium-ion battery changes during operation. The change can be used as an indicator of the permeability of the solid–electrolyte interphase (SEI) at the anode for Li+ permeation, which is a key factor to achieve high battery performance. The permeability is improved by adding film-forming additives to the electrolyte to modify the properties of the SEI.

      Waste not, want not: Waste valorization is an important component of a circular economy, but the current use of municipal solid waste is focused on energy production (waste-to-energy). We demonstrate here the economic and environmental advantages (resource preservation, lower carbon footprint, and toxicity impact) of a new waste-to-chemical technology for the production of urea, which is an important fertilizer and one of the top chemicals produced.
