The chemical industry relies on catalytic processes, which involve mainly heterogeneous
catalysts because they offer many advantages over their homogeneous counterparts such …

Heterogeneous catalysts undergo thermal-and/or adsorbate-induced dynamic changes
under reaction conditions, which consequently modify their catalytic behavior. Hence, it is …

This review addresses the most relevant aspects of vibrational spectroscopies (IR, Raman
and INS) applied to zeolites and zeotype materials. Surface Brønsted and Lewis acidity and …

Metallo-oxide (MO)-based bioinorganic nanocomposites promise unique structures,
physicochemical properties, and novel biochemical functionalities, and within the past …

Starting from the late seventies, the progressively increased availability of synchrotron light
sources allowed the execution of experiments requiring a high X-ray flux in a continuous …

There are many reasons to report on silica interacting with biomolecules. The most obvious
one is that on the Earth's crust, oxygen and silicon are the most abundant atomic species …

Many industrial catalysts contain isolated metal sites on the surface of oxide supports.
Although such catalysts have been used in a broad range of processes for more than 40 …

2. BACKGROUND Metallacycles of the transition metals were well-known and extensively
studied in the 1970s and 1980s8, 13, 14 and have been reviewed recently. 15, 16 …

Model systems are very important to identify the working principles of real catalysts, and to
develop concepts that can be used in the design of new catalytic materials. In this review we …

This critical review describes the reactivity of heterogeneous catalysts from the point of view
of four simple, but essential for Chemistry, molecules (namely dihydrogen, carbon …
