“…There is considerable interest in exploiting the potential of graphenes (Gs) as metal‐free catalysts . In the absence of metals, Gs exhibit catalytic activity in the oxidation of benzylic compounds, alcohols, and amines as well as in the hydrogenation of C−C multiple bonds and aromatic nitro compounds among other reactions . One of the challenges in carbocatalysis by Gs is to show that they can exhibit activity for reactions that up to now are believed to be promoted exclusively by metals, such as C−C couplings, condensations, rearrangements, and some types of oxidations .…”

“…In addition, theoretical models predict that B-doped Gr should be able to interact with molecular hydrogen 26 . There is only one precedent on the hydrogenation of ethylene using reduced GO (rGO), but the reaction required very high temperatures (500°C) and hydrogen excess to proceed, observing no conversion at 200°C and only 3.2% at 250°C, making the process uninteresting from the practical point of view 27 .…”

Graphenes in the absence of metals as carbocatalysts for selective acetylene hydrogenation and alkene hydrogenation

Catalysis makes possible a chemical reaction by increasing the transformation rate. Hydrogenation of carbon-carbon multiple bonds is one of the most important examples of catalytic reactions. Currently, this type of reaction is carried out in petrochemistry at very large scale, using noble metals such as platinum and palladium or first row transition metals such as nickel. Catalysis is dominated by metals and in many cases by precious ones. Here we report that graphene (a single layer of one-atom-thick carbon atoms) can replace metals for hydrogenation of carbon-carbon multiple bonds. Besides alkene hydrogenation, we have shown that graphenes also exhibit high selectivity for the hydrogenation of acetylene in the presence of a large excess of ethylene.

Generally, transition metal catalysts are essential for the reductive hydrogen atom transfer reaction, which is also known as the transfer hydrogenation reaction or the borrowinghydrogen reaction. It has been reported that graphene can be an active catalyst in ethylene and nitrobenzene reductions, but no report has described carbon-based materials as catalysts for alcohol amination via the borrowing-hydrogen reaction mechanism. Here we show the results from the preparation, characterization and catalytic performance investigation of carbon catalysts in transition metal-free borrowing-hydrogen reactions using alcohol amination and nitro compound/ketone reduction as model reactions. XPS, XRD, SEM, FT-IR and N 2 adsorption-desorption studies revealed that C ¼ O group in the carbon catalysts may be a possible catalytically active site, and high surface area is important for gaining high activity. The activity of the carbon catalyst remained unchanged after reuse. This study provides an attractive and useful methodology for a wider range of applications.
