A model is presented to explain the formation and morphologies of surfactant-silicate mesostructures. Three processes are identified: multidentate binding silicate oligomers cationic surfactant, preferential polymerization in interface region, charge density matching between surfactant silicate. The explains present experimental data, including transformation lamellar hexagonal mesophases, provides a guide for predicting conditions that favor lamellar, hexagonal, or cubic Model Q(230)...
Hydrogen is a promising energy carrier in future systems. However, storage of hydrogen substantial challenge, especially for applications vehicles with fuel cells that use proton-exchange membranes (PEMs). Different methods are discussed, including high-pressure and cryogenic-liquid storage, adsorptive on high-surface-area adsorbents, chemical metal hydrides complex hydrides, boranes. For the latter solutions, reversible options hydrolytic release off-board regeneration both possible....

Abstract Nanocasting is a powerful method for creating materials that are more difficult to synthesize by conventional processes. We summarize recent developments in the synthesis of various structured porous solids, covering silica, carbon, and other nonsiliceous solids created nanocasting pathway. Structure replication on nanometer length scale allows materials' properties be manipulated controlled manner, such as tunable composition, controllable structure morphology, specific...
Siliceous ordered mesoporous materials are well-investigated and -covered by several excellent reviews. Less work has been directed to non-siliceous materials, although these could have more wide-ranging applications. This review will address the synthesis properties of covering oxidic, non-oxidic, metallic, pure carbon frameworks. Organometallic frameworks, which typically not synthesized in presence surfactants, beyond scope this paper.
Ordered mesostructured porous silicas that are also macroscopically structured were created by control of the interface on two different length scales simultaneously. Micellar arrays controlled nanometer-scale assembly, and at static boundary between an aqueous phase organic phase, was achieved micrometer to centimeter scale. Acid-prepared mesostructures silica made with p6, Pm3n, P63/mmc structures in form fibers 50 1000 micrometers length, hollow spheres diameters 1 100 micrometers, thin...
In this work, we present a detailed study concerning the evaluation of metal-support interaction in high activity gold catalysts for CO oxidation. Using colloidal deposition method, model were prepared, which allow isolation effect support on catalytic activity. Prefabricated particles thus deposited different materials. Since process did not change particle sizes particles, only influence could be studied. TiO2, Al2O3, ZrO2, and ZnO used as Catalytic tests resolution transmission electron...
The discovery and investigation of novel efficient pathways for the conversion biomass into fuels chemicals are among big challenges facing heterogeneous catalysis nowadays. However, not all experience gained in transformation hydrocarbons over last 100 years can directly be transferred to conversion. In this article, we will discuss how specific properties pose new requirements on processes solids that used as catalysts their Due importance lignocellulosic materials, which constitute ca....
Zwei halten zusammen: Hohle Zirconiumoxid-Hüllen, die jeweils ein Gold-Nanopartikel enthalten (siehe Bild), sind stabil gegen Sintern und eignen sich als Heterogenkatalysatoren für Reaktionen wie Oxidation von CO an Luft. Calcinierung bei 800 °C verringert Aktivität "Au, @Zr2O" nicht.
The possible role of ammonia in a future energy infrastructure is discussed. review focused on the catalytic decomposition as key step. Other aspects, such removal from gasification product gas or direct fuel cells, are highlighted well. more general question integration an also covered.
The availability of feasible methods for hydrogen storage is one the key-maybe key-requirements large scale application PEM fuel cells in cars. There are principle four different approaches, i.e. cryostorage liquid form, high pressure storage, form a chemical compound which converted to by on-board reforming, or reversible kinds materials. New developments field make such systems attractive compared other options. This review will discuss possibilities and focus on presently most advanced...
Porous and high-surface-area materials are of interest to many scientific communities. Templating pathways can be used synthesize such with a high degree control over their structural textural properties. As templates molecular or supramolecular units added the synthesis mixture. They occluded in growing solid leave pore system after removal. For term "endotemplate" is introduced. Alternatively, pores which another created, thus providing scaffold for synthesis. After removal scaffold,...
Again and again again: The title reaction was achieved on a solid catalyst in covalent triazine-based framework formed by trimerization of 2,6-dicyanopyridine ZnCl2 melt. material possesses bipyridine units as coordination sites for platinum. It shows high activity can be separated easily from the mixture recycled several times without significant loss activity.
Porous carbon monoliths with defined multilength scale pore structures, a nitrogen-containing framework, and high mechanical strength were synthesized through self-assembly of poly(benzoxazine-co-resol) carbonization process. Importantly, this synthesis can be easily scaled up to prepare identical structures. By controlling the reaction conditions, porous exhibit fully interconnected macroporosity mesoporosity cubic Im3m symmetry withstand press pressure 15.6 MPa. The use amines in results...
Magnetic, highly porous ordered carbon of the CMK-3 and CMK-5 type with pure or carbon–nitrogen framework were nanoengineered by a sequence bulk manipulation steps. The materials can be used as efficient magnetic adsorbents (see picture) catalysts, but applications going far beyond these envisaged.
