VIP: Beneficial Role of Reduced Graphene Oxide for Electron Extraction in Highly Efficient Perovskite Solar Cells
Kyung Taek Cho, Dr. Giulia Grancini, Dr. Yonghui Lee, Dimitrios Konios, Dr. Sanghyun Paek, Prof. Emmanuel Kymakis and Prof. Mohammad Khaja Nazeeruddin
rGO for efficiency! The effect of incorporating reduced graphene oxide (rGO) within the electron-transport, active, and hole-transport layers of a perovskite solar cell is investigated. Incorporation of rGO into the mesoporous TiO2 matrix results in highly efficient solar cells with power conversion efficiency of up to 19.54 %.

- Effective Release of Lignin Fragments from Lignocellulose by Lewis Acid Metal Triflates in the Lignin-First Approach
Xiaoming Huang, Jiadong Zhu, Tamás I. Korányi, Dr. Michael D. Boot and Prof. Emiel J. M. Hensen

Less is more: Metal triflates are identified as a novel class of catalysts effective in the extraction of lignin fragments from lignocellulose. Model compound studies show that small amounts of metal triflates are effective in cleaving lignin–carbohydrate bonds. The tandem process is flexible, as good aromatic monomer yields (36–48 wt %) can be obtained from different woods in short reaction times.
- Catalytic Upstream Biorefining through Hydrogen Transfer Reactions: Understanding the Process from the Pulp Perspective
Dr. Paola Ferrini, Dr. Camila A. Rezende and Dr. Roberto Rinaldi

Union is strength: In catalytic upstream biorefining (CUB), the action of Raney Ni is limited to the species leached from the plant tissue into the liquor. Nevertheless, the substantial changes in the liquor composition (through the decomposition of carboxylic acids and H-transfer reductive processes on the lignin fragments) have major implications for the pulp composition, degree of polymerization, and morphology.
- Capacity Decay Mitigation by Asymmetric Positive/Negative Electrolyte Volumes in Vanadium Redox Flow Batteries
Jong Ho Park, Jung Jin Park, Prof. O Ok Park and Dr. Jung Hoon Yang
Version of Record online: 21 OCT 2016 | DOI: 10.1002/cssc.201601110
Pluses and minuses: The capacity of vanadium redox flow batteries tends to decrease very rapidly within the first tens of cycles, significantly lowering their practical energy density. The imbalanced crossover of vanadium species was found to remain very high until the total vanadium concentration difference between the positive and negative electrolytes reached ∼1 mol dm−3. To minimize this early imbalanced crossover, operation using an asymmetric positive/negative volume ratio is suggested.
- Bifunctional Ionic Liquids Derived from Biorenewable Sources as Sustainable Catalysts for Fixation of Carbon Dioxide
Vitthal B. Saptal and Prof. Bhalchandra M. Bhanage
Version of Record online: 20 OCT 2016 | DOI: 10.1002/cssc.201601228
Bifunctional Catalysts! Ionic liquids containing a quaternary alkyl ammonium cation and an amine anion are prepared and applied as organocatalysts for the chemical fixation of carbon dioxide to form cyclic carbonates and quinazoline-2,4(1 H,3 H)-diones. The presence of a hydroxyl group and a free amine group in the ILs has a synergistic effect on the activation of epoxides and carbon dioxide and the subsequent cycloaddition reactions.
- Suspension Electrodes Combining Slurries and Upflow Fluidized Beds
Hagai Cohen, Shaked Ein Eli, Morten Jõgi and Prof. Matthew E. Suss
Version of Record online: 20 OCT 2016 | DOI: 10.1002/cssc.201601008
Combo-electrode: A novel carbon-based suspension electrode is presented, combining a dense fluidized bed with a dilute slurry. Evidence of synergy is presented as measurements of electric conductivity of the combined electrode are at least an order of magnitude higher than the conductivity of the fluidized bed or slurry components alone. Such electrodes are promising towards applications in energy storage and water desalination by electrochemical systems.
