The demand for materials with particular and specific physico-chemical properties is constantly increasing. Thus, new multifunctional hybrid systems (based on inorganic oxides, organic moieties, metallic complexes or polymers) are being synthesised for a wide range of applications. Organic–inorganic hybrids may combine the advantages of inorganic solids (high mechanical, thermal and structural stability) and organic molecules or macromolecules (flexibility and functionality). This is particularly important in the field of catalysis, due to the intrinsic limitations of heterogeneous (nature of active sites and related catalytic performance) and homogeneous catalysts, which can catalyze a larger variety of reactions with high selectivity but suffer from recyclability issues. Moreover, multifunctional hybrid catalysts can be designed for tandem or cascade reactions. This has opened a fascinating field of research, with unprecedented complexity degrees related to the organic–inorganic interface. This Special Issue of Catalysts is aimed at providing an overview on the many aspects of hybrid catalysts, including smart design, advanced synthetic approaches, catalytic activity, physico-chemical characterization (including in situ and operando studies), computational modeling and structure-properties correlations.

Abstract: Supported metallic species have appeared as valuable catalysts in green chemistry because their high efficiency enable a wide applicability even at industrial scale. Silica is a versatile support capable to host metals enhancing stability and reactivity. Organic-inorganic hybrid materials have been widely used in this field and an efficient grafting of cyclodextrin onto the inorganic silica surface has been recently object of our study. In the present work we report the preparation of new solid supported copper and palladium catalysts mono or bimetallic. With the aim to effectively immobilize and stabilize the catalyst we exploited the features of β-CD derivative. The prepared catalysts were characterized about their physico-chemical properties by means of structural, textural and spectroscopic techniques, with the aim to investigate the structure of the β-CD stabilized metal species and to correlate their properties (dispersion, nuclearity, coordination and oxidation state) to their activity. To this aim, the catalyst were tested in coupling and in CH activation reactions, as well as in Cu(II) catalysed procedures.

Abstract: Hybrid organic-inorganic catalysts have been synthesized by anchoring N-heterocyclic carbene (NHC) on different inorganic supports with hierarchical porosity, in particular hierarchical HZSM-5 and SAPO-5. Hierarchical inorganic supports have been obtained both by top-down and bottom-up approaches and the role of hierarchical porosity has been evaluated. A detailed physico-chemical characterization has been performed on the hybrid organic-inorganic catalysts using a multi-techniques approach (XRD, volumetric analysis, ss-NMR and FTIR) in order to establish structure-properties relationship. Preliminary catalytic tests for benzoin condensation reactions were also performed.

Abstract: Three families of organosiliceous materials with different structuration level, order and textural properties (non-ordered, M41S and SBA-15 type materials) were prepared incorporating in their structural framework chiral pyrrolidine units with variable content. Likewise non-ordered mesoporous hybrid solids were obtained through a sol-gel process in fluoride medium while M41S and SBA-15 type materials were obtained through micellar routes with the presence of long chain neutral surfactants or block copolymers. Thanks to appropriate characterization studies and catalytic tests for the Michael addition between butyraldehyde and b-nitrostyrene, we showed how the void shapes and sizes present in the structure of hybrid materials control the diffusion of reactants and products as well as confine transition states and reactive intermediates. The best catalytic results, considering activity and enantioselectivity, were achieved in the presence of non-ordered material, NOH-Pyr-5%, that exhibited the highest BET area, with 96% yield and of 82% ee for the Michael adduct.
