“…The industrial production of VFAs is expected to increase in the next few years due to their diverse uses. Currently, more than 15 million tons of acetic acid are generated worldwide, and this value is expected to reach 20 million tons in 2025 [9]. Similarly, the demand for butyric acid is growing due to its use in pharmaceuticals, animal feed, and the food industry.…”

As a response to the environmental and societal issues that emanate from the high reliance on fossil fuels, the world is now transitioning toward a circular bioeconomy. Acidogenic biohydrogen production is envisaged as a clean fuel of the future due to its non-polluting features and affordability. The major encumbrance for the industrialization of this process is due to the accumulation of metabolic inhibitors (volatile fatty acids (VFAs)), which lower the H2 yields. This review discusses novel methods that can be adopted to valorize the acidogenic VFAs via a “cascade microbial biorefinery-based” approach that enables this process to be economically feasible as it leads to the concomitant production of diverse high-value-added products. The work also elucidates the key setpoint parameters governing the recovery of VFAs during the acidogenic H2 process. It further explores the recent advances in the use of VFAs in microbial biorefineries. Finally, the paper provides some recommendations that might help develop acidogenic microbial biorefineries in the future. Studies focusing on microbial biorefineries tailored towards the valorization/beneficiation of acidogenic VFAs are very scarce in the literature. This work aims to provide new insights into microbial biorefinery-based processes involving the use of acidogenic VFAs as substrates.

Direct catalytic oxidation (DCO) of coalbed methane to methanol has been considered as a significant technology for highly efficient and clean utilization of coal resources. Herein, the Cu-based spherical micromesoporous material (Cu/SMMM) was successfully prepared by using a sepiolite-derived silica source, and the DCO of methane to methanol was achieved under a low-temperature gas-phase system. Under the optimal reaction conditions, the Cu/SMMM accomplished the maximum methanol production of 69.3 μmol/g cat /h and methanol selectivity of 81.2% with full activation at 450 °C in air for 4 h, and the reaction was carried out at 320 °C for 1 h. Various characterizations demonstrated that the unique SMMM promoted the dispersion of copper oxides to form more active copper species and Lewis acidic sites (LAS). The variable-temperature FTIR, XAS, and NO-IR analyses identified that the highly dispersed dimeric copper species such as ([Cu 2 (μ-O)] 2+ or [(Cu 2 O 2 ) 2+ ]) in Cu/SMMM was the major active species for DCO of methane into methanol. Additionally, combined with in situ FTIR analysis, the catalytic mechanism was revealed, in which the adsorbed methane species could be converted to CH 3 * species. Subsequently, CH 3 * species bound to oxygen of the dimeric copper species to form CH 3 O* species, which was then converted to methanol in the presence of water.

“…In the 1990s, George A. Olah, a Nobel prize laureate in chemistry, advocated a “Methanol Economy” concept. According to this proposal, methanol was a suggested future economy in which methanol and dimethyl ether replace fossil fuels for energy storage, ground transportation fuel, and raw material for synthetic hydrocarbons and their products. ,− The importance of the methanol economy is that it can reduce our dependency on fossil fuels and their harmful effects on the environment. − Methanol also offers an alternative to the other proposed hydrogen economy, though this concept is not exclusive . Methanol and hydrogen are potential alternatives to fossil fuels for energy storage and transportation.…”

Methanol is a fundamental feedstock and is widely used in the chemical and petroleum industries. It can serve as a C1 source to make a variety of C−C and C−N bond formation and dehydrogenative coupling products, which have important applications in natural products and drug discovery. A high hydrogen content (12.5 wt%) of methanol makes it an effective H 2 donor for the transfer hydrogenation of various reducible functional groups. A plethora of various transition metal-based dehydrogenative processes have been developed using methanol. Notably, recent review articles focused on the C1 aspect of methanol. However, a more updated review that examines the challenges and applications of methanol as both a C1-source and H 2 -source in organic transformations contributing to the concept of the methanol economy has not been presented yet. This Review summarizes the transition metal-based (homogeneous, heterogeneous, and photo-) catalyst system for C-, N-, and O-methylation of ketones, alcohols, amides, nitriles, heterocyclic compounds, sulfones, amines, amides, sulfonamides and direct N-methylation of nitro compounds under borrowing hydrogen strategy and N-formylation of amines using methanol under acceptorless dehydrogenation coupling using methanol as a C1 source. It also covers insights into reaction mechanisms and the role of carefully selected ligands in the metal catalysis for methanol activation and incorporation of -CD 3 , methylation of drug molecules. Moreover, it describes transfer hydrogenation of various functional groups such as aldehydes, ketones, alkynes, and nitro with methanol as an H 2 donor in detail.
