TL;DR: In this paper, a combination of time-resolved synchrotron μ-X-ray diffraction computed tomography (μ-XRD-CT) and μ-pair distribution function computed tomograph (μPDF-CT), was applied for the study of an individual Co/γ-Al2O3 catalyst pellet during reduction and the early stages of the Fischer-Tropsch synthesis (FTS) reaction, revealing insight into the solid-state changes occurring from within such crystalline materials.

TL;DR: The simultaneous isomorphous substitution of Al(III) and P(V) ions, in an aluminophosphate framework, with redox active Co( III) and Ti(IV) metal ions, generates highly active single-site heterogeneous catalysts that exhibit considerable synergy, compared to their corresponding monometallic analogues, in the catalytic epoxidation of olefins.

TL;DR: In this article, the role of well-defined and isolated multifunctional solid-acid active centers, employing Mg(II)Si(IV)AlPO-5 nanoporous architectures, has been demonstrated, with a view to affording structure-property correlations compared to its corresponding mono-substituted analogues (Mg( II)AlPo-5 and Si(IV),AlPO5).

TL;DR: In this paper, the geometry of VOF3(MeCN) is characterized by micro-analysis, IR, UV/Vis and multinuclear NMR [51V, 19F{1H, 31P{ 1H}, 1H] spectroscopy, the data showing them to besixcoordinate with trans F-V-F units and the neutralligands trans to O and F, respectively.

TL;DR: A combined electronic structure computational and X-ray absorption spectroscopy study was used to investigate the nature of the active sites responsible for catalytic synergy in Co-Ti bimetallic nanoporous frameworks, identifying a unique Co-O-Ti bond which serves as the loci for the superior performance of the bimet metallic catalyst, when compared with its analogous monometallic counterpart.
