Catalysis is recognized as a key and unavoidable tool in the development of truly new and efficient chemical reactions, as well as their economic and environmental sustainability. Supported metal catalysts are largely used in the manufacture of a wide range of fine and specialty chemicals including pharmaceuticals, flavor and fragrances, herbicides and pesticides, polymer materials, pigments and dyestuffs, and plastic and rubber additives. In this view, significant efforts have been directed toward the rational design and development of supported metal catalysts using advanced synthetic approaches that allow one to fine-tune the morphology and geometry of the support at nanoscale level and the chemical nature and size of the catalytically active site, as well as its local environment. The rapid development of characterization techniques that are able to reveal the structural, morphological, compositional, and textural properties of catalysts at an atomic level, even in in-situ or operando conditions, resulted in a huge contribution to this goal. Mimicking nature’s enzymes, the new generation of supported metal catalysts offer the possibility to carry out reactions with increased turnover rates and selectivity and, in favorable circumstances, with high stability/recyclability thanks to their very low metal leaching and poisoning.
Combined with this ambitious objective is the progress of other enabling technologies, i.e., techniques that facilitate the preparation of the desired product in the most efficient way and with minimal penalty to the environment. These advancements include the use of non-conventional reaction media, solvent-free reactions, continuous-flow approaches, and alternative energy-transfer methods, such as microwave, photochemical, and sonochemical conditions. Further aspects of current strong interest, in connection with supported metal catalysts, focus on the implementation of multi-step or cascade processes and the exploitation of bio-sustainable feedstocks.
The present Special Issue aims to present the recent development in the synthesis, characterization, and use of supported metal catalysts for chemo-, regio-, and stereoselective organic transformations in the fine and specialty chemicals field. Studies focused on the structure–activity/selectivity relationship in supported metal catalysts, including advanced characterization tools (both ex situ and in situ), are welcome. The issue is open to both original research papers and reviews.

Supported ruthenium as hydrogenation catalyst for production of fine chemicals

Abstract: The continuous production of clean fine chemicals using supported catalysts cannot be over-emphasized. Usually the support is found to have substantial effect on both the selectivity and activity of the bound catalysts. The selective hydrogenation products have been achieved from among others, the supported highly active ruthenium catalysts. These catalysts are broadly used for selective hydrogenation of carbonyl group based compounds particularly those in the vicinity of conjugated or isolated double bonds. The carbonyl based compounds are some of most known difficult bonds to hydrogenate. Work with this metal has led to the production of a variety of fine chemicals which are important in pharmaceutical, food and agrochemical industries. We shall therefore review many research works that are reported on hydrogenation processes limited to the catalysys by supported ruthenium metal. A few examples of the hydrogenation reactions to be covered include preparation of 1,3-propanediol from 3-hydroxypropanal using ruthenium supported on activated charcoal, preparation of γ-valerolactone by hydrogenation of levulinic acid catalysed by ruthenium supported on sulfur-doped carbon material, aqueous phase hydrogenation of levulinic acid to γ-valerolactone on supported Ru catalysts prepared by microwave-assisted thermolytic method, preparing carbonyl and alcohol compound by transfer hydrogenation, and many other reactions. We shall also include their preparation techniques, various support materials and their significance, products and applications.
Metal-amyloid complexes as novel catalytic bio-nanomaterials
Authors: Esteban Nova, Rodrigo Diaz-Espinoza

Abstract: Amyloids are fibrillar structures composed of highly ordered protein or peptide monomers stacked through hydrogen-bonded intermolecular contacts. Despite being classically associated to hallmark human pathologies such as Alzheimer’s and Parkinson’s diseases, growing research has shown that nature has exploited the amyloid fold across all kingdoms of life for diverse biological functions due to their unique mechanical properties. Moreover, recent findings have demonstrated that rationally designed short peptides can self-assembly into amyloids that can bind different divalent metals. The resulting metal-amyloid complexes can exhibit catalytic reactivity towards different model compounds, giving rise to metal-decorated assemblies that act as catalytic surfaces. Such rational design approach combines both the mechanical and reactivity properties of amyloids for the generation of novel active bio-nanomaterials that can potentially have diverse applications in the production of fine chemicals.
