The electrografting process has been applied to a new monomer in order to induce reactivity to the surface of various conducting substrates which are then appropriate for the anchoring of a large variety of molecules (catalysts, proteins, amino-polymers etc.).

We observed distinct chemoselectivities for the gold-catalyzed transformation of cis-1-oxiranyl-1-alkynylcyclopropanes 1 into various halogenated products in the presence of suitable Au(III) catalysts and N-halosuccinimide (halo = chloro, bromo and iodo).

The straightforward synthesis of novel enzyme-metalNP nanobiohybrids in aqueous medium was developed. These new nanobiohybrids were excellent multivalent catalysts combining both activities in various sets of synthetic reactions even at ultra-low concentrations (ppb amount).

The recycling of chemicals and generation of alternative energy are central topics in the efforts toward sustainable development. Among these, research on plastics recycling and fuel cells has received significant attention, with the aim of designing novel catalysts to improve yield and efficiency. We highlight our work on these areas focusing on the chemical depolymerization of polyethylene te...

Modern chemical synthesis makes heavy use of different types of catalytic systems: homogeneous, heterogeneous and nano-sized. The latter--nano-sized catalysts--have given rise in the 21st century to a rapidly developing area of research encompassing several prospects and opportunities for new technologies. Catalytic reactions ensure high regio- and stereoselectivity of chemical transformations,...

Microstructural characteristics of various real Cu/ZnO/Al2O3 catalysts for methanol steam reforming (MSR) were investigated by in situ X-ray diffraction (XRD), in situ X-ray absorption spectroscopy (XAS), temperature programmed reduction (TPR) and electron microscopy (TEM). Structure–activity correlations of binary Cu/ZnO model catalysts were compared to microstructural properties of the ternar...

The heterogenization of homogeneous catalysts can be achieved by immobilization, grafting, anchoring or encapsulating them in an inert solid like organic polymer or inorganic support. Transition metal complexes having good catalytic properties are immobilized through encapsulation in the super cages of zeolites is called zeolite encapsulated metal complexes (ZEMC) or ship-in-the-bottle complexe...

The Suzuki coupling reaction is one of the most practiced classes of catalytic C-C bond formation. The development of newmeans of activating molecules and bonds over old catalysts for C-C bond formation is a fundamental objective for chemists. Here, we report the room-temperature C-C bond formation over heterogeneous Pd catalysts by light-mediated catalyst activation. We employ stimulated elect...

Molybdenum containing catalysts are widely used for the selective oxidation of propene in the presence of gas phase oxygen at temperatures above ~600 K. Crystalline (Mo,V,W)5O14 constitutes a three-dimensional model system for the more complex molybdenum based mixed oxide catalysts that are employed industrially for various partial oxidation reactions [1]. However, little is known about the coo...
