    1. Direct Production of 5-Hydroxymethylfurfural via Catalytic Conversion of Simple and Complex Sugars over Phosphated TiO2

      Luqman Atanda, Dr. Abhijit Shrotri, Swathi Mukundan, Dr. Qing Ma, Dr. Muxina Konarova and Dr. Jorge Beltramini

      Article first published online: 3 AUG 2015 | DOI: 10.1002/cssc.201500395

      A matter of phases: The potential of sustainable HMF production from cellulosic biomass is demonstrated in this article. Phosphated TiO2 effectively catalyzes the conversion of sugars to HMF in a biphasic reactor. In addition, selective formation of HMF is enhanced by adding an aqueous-phase modifier to the biphasic medium. Under both batch and continuous flow conditions, direct conversion of pretreated cellulose to HMF is achievable.

      A matter of time: Solar cells sensitized with one of the most promising and efficient carbazole dyes are studied using a number of complex techniques (from ultrafast and fast laser spectroscopy to electrochemical impedance measurements) to provide information about partial charge separation processes occurring from femtoseconds to seconds in complete devices. The observed features have a direct impact on the performance of the solar cells, and therefore are crucial for the construction of more efficient devices.

      Titanium(IV) in the Organic-Structure-Directing-Agent-Free Synthesis of Hydrophobic and Large-Pore Molecular Sieves as Redox Catalysts

      Dr. Jingui Wang, Prof. Dr. Toshiyuki Yokoi, Prof. Dr. Junko N. Kondo, Prof. Dr. Takashi Tatsumi and Prof. Dr. Yanli Zhao

      Article first published online: 31 JUL 2015 | DOI: 10.1002/cssc.201500857

      Thumbnail image of graphical abstract

      The Back Cover picture shows two different synthetic routes to prepare microporous titanosilicate molecular sieves. One is a traditional route that requires expensive organic molecules used as organic structure-directing agents (OSDA, right), whereas the other one is a newly developed OSDA-free route that does not require any organic molecules (left). The absence of an organic template in the synthesis could avoid environmental problems as pyrolysis of the organic template in the traditional route generates toxic gases such as CO2 and NOx. Moreover, titanosilicate molecular sieves prepared using the OSDA-free route show considerably higher catalytic activity for the epoxidation of bulky cyclooctene with H2O2. More details can be found in the Communication by Wang et al. (DOI: 10.1002/cssc.201500443).

      Er zit een Aldertje onder het gras: The classical two-step approach to furanics-derived aromatics, via Diels–Alder (DA) aromatization, is modified into a three-step procedure to avoid retro-DA reactions. The new sequence involves a mild hydrogenation step to obtain a stable oxanorbornane intermediate. Subsequent dehydration and dehydrogenation using a physical mixture of acidic zeolites or resins in combination with metal on a carbon support then gives high yields of aromatics under relatively mild conditions.

A mechanochemically reduced SiO2−x/TiO2−x composite is designed by thermodynamic calculations and synthesized by high-energy mechanical milling as a promising anode material for lithium-ion batteries. By incorporation of Ti, amorphous SiO2 can be effectively reduced during the synthesis, leading to the in situ formation of a SiO2−x/TiOx composite that shows a high reversible capacity with excellent cycle performance.

    3. Activation Effect of Fullerene C60 on the Carbon Dioxide Absorption Performance of Amine-Rich Polypropylenimine Dendrimers

      Dr. Enrico Andreoli  and Prof. Andrew R. Barron 

      Article first published online: 24 JUL 2015 | DOI: 10.1002/cssc.201500605

      Thumbnail image of graphical abstract

      Favoring accessibility: The addition of fullerene C60 to polypropylenimine (PPI) dendrimers to form PPI–C60 cross-linked composites results in a reduction of the energy activation barrier of CO2 absorption. This finding supports the existence of a nonaffinity “repulsive” effect between hydrophobic C60 and hydrophilic amines that forces the latter to spread out and be actively exposed to CO2.

      Thumbnail image of graphical abstract

      The Cover picture shows a possible solution to the low round-trip efficiencies of Li–O2 batteries (the most promising next-generation battery) owed to the poor reversibility of the formation of the discharge product Li2O2 and the associated high polarization potentials. This can be achieved by controlling the phase structure and morphology of Li2O2. By embedding Co nanoparticles in carbon nanofibers, a uniform film-like amorphous Li2O2 is formed and both the charge and discharge overpotentials are decreased. More details can be found in the Full Paper by Kim et al. (DOI: 10.1002/cssc.201500520).

      Pore some more: Mesoporous carbon materials (i.e., CMK-3 and MSU-F-C) are used in Li–O2 batteries to examine their effect on the morphology of the discharge products and to improve the discharge capacities and polarization of cycling. Large interconnected pores also increase the rate capabilities of the cells. These results demonstrate that control of the porous structure of the cathode is needed to improve the performance of Li–O2 batteries.

      Isolating and conducting: A quasi-top-open insulating metal oxide overlayer is deposited on a nanoparticulate TiO2 (np-TiO2) layer for perovskite solar cells. This insulating hole-blocking layer mainly covers the bottom part of the mesoporous layer with less coverage at the top to keep sufficient electron conduction within the perovskite film. It effectively prevents charge recombination, giving rise to an open-circuit voltage that is higher for a cell without this layer.

The most important aspect of using hindered glyme electrolytes with graphite electrodes is the absence of exfoliation of the graphite at both room temperature and higher operating temperature (70 °C) without compromising cycling capacity. The hindered glyme chemistry is rich and can open up new horizons for energy storage.

      Modulation of Li2O2: Cobalt nanoparticles (Co NPs) embedded in carbon nanofibers (Co–CNFs) are introduced as air cathode in lithium–oxygen batteries. Co NPs could induce a charge localization of Co–CNFs and the formation of amorphous Li2O2 as discharge product. Because amorphous Li2O2 can be decomposed more easily than crystalline Li2O2, the charge overpotential is reduced effectively.

      The Back Cover picture shows a solution-processed thin film of semi-conducting CuFeO2 held in front of the sun. An impressive performance is reported using this material as a photocathode for the reduction of water molecules to hydrogen (as depicted in the bottom right corner) under solar radiation. In addition to being fully solution processable, the copper-based delafossite (crystal structure is shown in the top right corner) is a class of material known for being stable in aqueous environments. Moreover, it is only composed of earth-abundant materials, as suggested by the delafossite ore shown in the bottom right corner. Overall, these properties make p-type CuFeO2 a very attractive material in the quest for inexpensive, sustainable, and stable direct solar water splitting for the generation of carbon-free hydrogen.

      Pushing through it: A series of new β-functionalized push–pull-structured porphyrin dyes are synthesized. Together, these dyes allow the effect of the π-conjugated spacer on the performance of dye-sensitized solar cells (DSSCs) to be assessed. The highest conversion efficiency in the present study (8.2 %) is achieved by using a doubly β-butadiene-linked porphyrin as the sensitizer with a cobalt-based redox shuttle as the mediator.
