“…This highly selective methane oxidation process could be scaled up by combining efficient separation of the products from the effluent and recycling of the unconverted CH 4 and O 2 reactants 29 . Moreover, the fact that the molar ratio of HCHO to CO in the products is~1.0 makes them potentially desired for the downstream acetic acid synthesis via hydrogenation of HCHO to methanol and its subsequent carbonylation 30,31 and also for glycolic acid synthesis via direct carbonylation of HCHO 32 . The detected C 2 H 6 and C 2 H 4 products are likely ascribed to methane oxidative coupling as we reported previously 21,26 , reflecting the ability of B 2 O 3 -based catalysts to produce C 2+ molecules from direct methane oxidation.…”

Direct oxidation of methane to value-added C1 chemicals (e.g. HCHO and CO) provides a promising way to utilize natural gas sources under relatively mild conditions. Such conversions remain, however, a key selectivity challenge, resulting from the facile formation of undesired fully-oxidized CO2. Here we show that B2O3-based catalysts are selective in the direct conversion of methane to HCHO and CO (~94% selectivity with a HCHO/CO ratio of ~1 at 6% conversion) and highly stable (over 100 hour time-on-stream operation) conducted in a fixed-bed reactor (550 °C, 100 kPa, space velocity 4650 mL gcat−1 h−1). Combined catalyst characterization, kinetic studies, and isotopic labeling experiments unveil that molecular O2 bonded to tri-coordinated BO3 centers on B2O3 surfaces acts as a judicious oxidant for methane activation with mitigated CO2 formation, even at high O2/CH4 ratios of the feed. These findings shed light on the great potential of designing innovative catalytic processes for the direct conversion of alkanes to fuels/chemicals.

“…One possible pathway consists of using CO 2 as a raw material in organic chemical reactions. Different ways for the utilisation of CO 2 as a carbon source have been proposed, such as carbonilation reactions, dry reforming of methane and direct hydrogenation of CO 2 to methanol or dimethyl ether (DME) [1][2][3][4][5][6]. The latter reaction offers an interesting perspective as it can push towards the production of olefins via methanol/DME.…”

The synthesis of dimethyl ether (DME) is an important step in the production of chemical intermediate because it is possible to prepare it by direct hydrogenation of CO2. This paper reports the effect of different zeolitic frameworks (such as: BEA, EUO, FER, MFI, MOR, MTW, TON) on methanol conversion, DME selectivity and catalyst deactivation. The effect of crystal size, Si/Al ratio and acidity of the investigated catalysts have been also studied. Finally, the kinetic parameters (such as: ∆H, ∆S and ∆G) have been evaluated together with pre-exponential factor and activation energy for catalysts with FER and MFI structure topology.

“…Hydroaminocarbonylation of olefins, aminocarbonylation of aryl iodides, and oxidative carbonylation of amines occurs with the application of bulk Pd catalyst without the use of organic ligands [ 94 , 95 ]. Iridium and immobilized-rhodium catalyze the methanol carbonylation process, leading to the formation acetic acid [ 96 ]. An interesting fact is that membranes, e.g., chitosan, polyamide, polyvinyl alcohol, are used to catalyze carbonylation reactions [ 97 ].…”

This publication presents the new trends and opportunities for further development of coordination compounds used in the chemical industry. The review describes the influence of various physicochemical factors regarding the coordination relationship (for example, steric hindrance, electron density, complex geometry, ligand), which condition technological processes. Coordination compounds are catalysts in technological processes used during organic synthesis, for example: Oxidation reactions, hydroformylation process, hydrogenation reaction, hydrocyanation process. In this article, we pointed out the possibilities of using complex compounds in catalysis, and we noticed what further research should be undertaken for this purpose.
