Metallic catalysts are capable of designing multifunctional for efficient CO2−ODP reaction owing to their high abilities C−H scission, CO2 capture/activation, and coke removal. In this review, the catalyst design concepts metallic materials recent developments in summarized, categorizing them as monometallic, bimetallic multimetallic materials.

Several reactor configurations have been tested for catalytic propane dehydrogenation employing Pt-Sn/MgAl2O4 as a catalyst. Pd-Ag alloy membranes coupled to the multifunctional Two-Zone Fluidized Bed Reactor (TZFBR) provide an improvement in propane conversion by hydrogen removal from the reaction bed through the inorganic membrane in addition to in situ catalyst regeneration. Twofold process ...

This paper describes a simple and environmentally friendly method for the preparation of highly stable dispersions of Fe3O4 nanoparticles with controlled morphologies, in the same synthesis system for the first time. During the process, the Fe3O4 nanoparticles are formed using urease as a multifunctional reagent, including catalyst, template and dispersant, due to its enzymatic activity and spe...

Bacterial MCCs (multihaem cytochromes c) represent widespread respiratory electron-transfer proteins. In addition, some of them convert substrates such as nitrite, hydroxylamine, nitric oxide, hydrazine, sulfite, thiosulfate or hydrogen peroxide. In many cases, only a single function is assigned to a specific MCC in database entries despite the fact that an MCC may accept various substrates, th...

A convenient zinc(II) chloride-catalyzed regioselective propargylation/amination/cycloisomerization process has been developed for the synthesis of substituted pyrrole derivatives from propargylic acetates, enoxysilanes and primary amines. Various aromatic and aliphatic propargylic acetates participate well in the reaction, providing the propargylation/amination/cycloisomerization products in g...

7-Azaisatin and 7-azaoxindole skeletons are valuable building blocks in diverse biologically active substances. Here 7-azaisatins turned out to be more efficient electrophiles than the analogous isatins in the enantioselective Morita-Baylis-Hillman (MBH) reactions with maleimides using a bifunctional tertiary amine, β-isocupreidine (β-ICD), as the catalyst. This route allows a convenient approa...

The ability to devise and design multifunctional active sites at the nanoscale, by drawing on the intricate ability of enzymes to evolve single-sites with distinctive catalytic function, has prompted complimentary and concordant developments in the field of catalyst design and in situ operando spectroscopy. Innovations in design-application approach have led to a more fundamental understanding ...

We describe, for the first time, a highly regioselective hydrosilylation of propargylic amines. The reaction utilizes PtCl2/XantPhos catalyst system to deliver hydrosilanes across alkyne afford multifunctional allylic amines in high yields. is tolerant wide variety functional groups and provides value intermediates with two distinct handles. synthetic applicability has been shown through synthe...
