“…For the liquid-phase reaction, the reported catalysts were mainly based on Ru and Cu, which possess excellent dehydrogenation activity. In fact, DMM is often observed as a byproduct in liquid-phase decomposition of methanol to H 2 in the presence of homogeneous Ru complexes or supported Ru/C; − however, DMM selectivity remained usually low owing to the prevailing formation of FA and MF in the liquid phase. The research group of Shinoda studied the catalytic behaviors of Cu-ZnO/SiO 2 in the liquid-phase methanol dehydrogenation reaction .…”

The increasing concerns regarding exhaust and CO 2 emissions from fossil-based transportation fuels have propelled intensive research aimed at finding alternative fuel candidates to realize a clean and renewable fuel system. In this context, dimethoxymethane and its derivatives oxymethylene ethers, a class of oxygenated synthetic fuel, have recently attracted increasing interest because of their fascinating characteristics as a diesel blend compound to significantly reduce soot and nitrogen oxide formation. At present, dimethoxymethane production primarily relies on an established two-step process comprising methanol oxidation and methanol condensation with formaldehyde. Several new synthetic routes based on methanol or CO 2 /H 2 have been proposed by adopting a reaction coupling strategy, which enables the production of dimethoxymethane in one step. A large variety of bi-and multifunctional catalysts have been developed for each synthetic route. This Review comprehensively summarizes the latest advances in synthetic approaches, catalyst systems, structure−activity relationships, and reaction mechanism for the catalytic synthesis of dimethoxymethane. Comparisons regarding the features and limitations of different synthetic approaches as well as the related catalytic materials are also provided in order to indicate possible directions for future research, especially on the rational design of catalysts, a vital factor for the commercial production of dimethoxymethane.

“…There has been no data available so far about the behavior of mixed iron-ruthenium supported activated carbon catalysts in methanol decomposition and their possible application in the process regulation. It is shown that the selectivity of methanol decomposition carried out in the presence of mono-component catalysts comprising iron [48,49] or ruthenium supported on activated carbon depends strongly on reaction conditions [49,50]. The present paper aims at studying changes in the phase composition and catalytic properties of iron supported activated carbon materials with incorporated ruthenium.…”
