Abstract Direct methane to methanol conversion is a dream reaction in industrial chemistry, which takes inspiration from the biological production catalysed by monooxygenase enzymes (MMOs). Over years, extensive studies have been conducted on this topic bioengineering MMOs, and tailoring methods isolate MMOs active form. Similarly, remarkable achievements noted other activation strategies such as use of heterogeneous catalysts or molecular catalysts. In review, we outline metabolism performed methanotrophs detail latest advancements site structures catalytic mechanisms both types MMOs. Also, recent progress bioinspired approaches using various catalysts, especially first‐row transition metal zeolites mechanistic insights are discussed. addition, complexes “Periana catalyst” for through methyl ester formation presence strong acids also detailed. Compared zeolites‐mediated field, utilisation application still its nascent phase further research required overcome limitations these effectively.

Partial oxidation of methane (POM) is achieved by forming air-methane microbubbles in saltwater to which an alternating electric field applied using a copper oxide foam electrode. The solubility increased putting it contact with water containing dissolved KCl or NaCl (3%). Being fully dispersed as (20-40 µm diameter), reacts more hydroxyl radicals (OH·) at the gas-water interface. voltage (100 mV) generates two synergistic POM processes dominated Cl- → Cl· + e- and O2 -• under positive negative potentials, respectively. By tuning frequency amplitude, extent path process can be precisely controlled so that than 90% methanol selectively formed compared byproducts, dichloromethane, acetic acid. conversion yield estimated 57% rate approximately 887 µM h-1. This method appears have potential for removing from air seawater converting higher-concentration sources into value-added methanol.

In the present study, 76 different metal-oxide-supported-transition-metal catalysts were prepared using 11 metal oxides (MgO, Al2O3, SiO2, TiO2, V2O5, ZrO2, Nb2O5, MoO3, Ta2O5, WO3, and La2O3) seven 3d metals (V, Mn, Fe, Co, Ni, Cu, Zn). The supported catalysts, along with single oxides, screened to identify catalytically active lattice oxygen structures for partial oxidation of CH4 formaldehyde methanol. Fe/MoO3, Fe/V2O5, particularly Fe/Nb2O5 found be highly effective. Structural analysis Fe sites in was performed high-energy-resolution-fluorescence-detected K-edge X-ray absorption near-edge structure spectroscopy, revealing that FeNbO4, FeMoO4, FeVO4 species Fe/Nb2O5, respectively, are responsible their partial-oxidation activities. contrast, Fe2O3 formed Fe/Al2O3, Fe/SiO2, Fe/Ta2O5, Fe/WO3 complete CO2 than oxidation, as MgFe2O4, LaFeO3, TiFe2O5 Fe/MgO, Fe/La2O3, Fe/TiO2, interstitial solid solution Fe3+ ZrO2 generated Fe/ZrO2. Furthermore, while Fe/WO4 ineffective FeWO4 by a hydrothermal method exhibits high selectivity oxidation. Additionally, previous studies have shown CuWO4 CuMoO4 Accordingly, ABO4 (where A is B group 5 or 6 metal) indicated viable design basis development
