Cover Picture: Towards a Sustainable Manufacture of Hierarchical Zeolites (ChemSusChem 3/2014)
The Cover picture illustrates the importance of considering the ecological and economical footprint associated with the manufacture of newly developed (catalytic) materials. These aspects, which ultimately determine the large-scale implementation of catalysts, usually receive little attention in the open literature. Prof. Javier Pérez-Ramírez and Dr. Danny Verboekend consider the case of hierarchical zeolites (HZ), which are superior heterogeneous catalysts for numerous established and emerging applications. Focusing on the use of demetallation treatments, they present approaches to prepare these advanced materials more efficiently by increasing reactor productivity, recycling waste streams, avoiding the combustion of organics, and minimizing work-up efforts. More detail is given in the Full Paper by Verboekend and Pérez-Ramírez on page 753, while more information about the research group is available in the Cover Profile (DOI: 10.1002/cssc.201400062).
Inside Cover Picture: Fast Pyrolysis of Wood for Biofuels: Spatiotemporally Resolved Diffuse Reflectance In situ Spectroscopy of Particles (ChemSusChem 3/2014)
The inside cover picture depicts diffuse reflectance spectroscopy of visible light and compositional characterization of terrestrial biomass during pyrolysis. Dauenhauer et al. developed this technique to address one of the major challenges of biomass pyrolysis for biofuels: the complexity of characterizing the integrated chemistries of lignocellulosic feedstocks. For over 50 years, research has focused on describing lignocellulosic conversion using multi-parameter reaction modeling, for which the number of parameters greatly exceeds the capability for experimental validation. This new technique spatiotemporally characterizes for the first time the composition of reacting particles at industrial conditions. More details can be found in the Full Paper by Dauenhauer et al. on page 765 (DOI: 10.1002/cssc.201301056).
Back Cover: The Catalytic Pathways of Hydrohalogenation over Metal-Free Nitrogen-Doped Carbon Nanotubes (ChemSusChem 3/2014)
The back cover picture shows how nitrogen-doped carbon nanotube catalysts afford excellent reactivity for acetylene hydrochlorination. The research team led by Professor Fei Wei at Tsinghua University and Prof. Dang Sheng Su at the Institute of Metal Research found green alternative mercury-free catalysts for hydrohalogenation. The quaternary nitrogen species exhibiting positive charges played a role analogous to metal cation complexes with vacancies and increased the probability of acetylene chemisorption and formation of acetylene-pseudo-metal complexes. More details can be found in the Communication by Zhou et al. on page 723 (DOI: 10.1002/cssc.201300793).
