Electro-assisted methane oxidation to formic acid via in-situ cathodically generated H2O2 under ambient conditions

Nature Communications, 2023
Direct partial oxidation of methane to liquid oxygenates has been regarded as a potential route to valorize methane. However, CH4 activation usually requires a high temperature and pressure, which lowers the feasibility of the reaction.

Observation of induction period and oxygenated intermediates in methane oxidation over Pt catalyst

iScience, 2023
Summary: Selective oxidation of methane is one of the most attractive routes for methane to chemicals. However, mechanistic understanding and avoiding over-oxidation have great challenges because of its very rapid reaction rate. Herein, a capillary micro-

Active pathways of anaerobic methane oxidization in deep-sea cold seeps of the South China Sea

Microbiology Spectrum, 2023
Anaerobic oxidation of methane (AOM) is critical for controlling methane emissions from deep-sea cold seeps. Microbial groups associated with different AOM processes have been briefly investigated, but the AOM activities associated with the utilization ...

Features of methane emission into the atmosphere over buried landfill bodies in urbanized ecosystems of Moscow [PDF]

E3S Web of Conferences, 2021
On the outskirts of cities landfill bodies are formed, the territories of which are later used in urban planning. Over the buried landfill soils which represent construction and household garbage, methane flows are formed, which worsen the environmental ...

Methane oxidation of green-house soils

浙江大学学报. 农业与生命科学版, 2002
Methane oxidation of green-house soils was detected. The results showed that methane oxidation ability was different in various soils and possibly it was related with the basic properties of the soils.

Identification of functionally active aerobic methanotrophs and their methane oxidation potential in sediments from the Shenhu Area, South China Sea

China Geology, 2022
: Large amounts of gas hydrate are distributed in the northern slope of the South China Sea, which is a potential threat of methane leakage. Aerobic methane oxidation by methanotrophs, significant methane biotransformation that occurs in sediment surface

An investigation of the comparative reactivities of ethane and ethylene in the presence of oxygen over Li/MgO and Ca/Sm2O3 catalysts in relation to the oxidative coupling of methane [PDF]

, 1989
In order to examine the importance of the further oxidation of the desired C2 products in the oxidative coupling of methane, ethylene and ethane have been added to the feed (containing methane and oxygen) to a Li/MgO or Ca/Sm2O3 catalyst.

Assessing the Effect of Humic Substances and Fe(III) as Potential Electron Acceptors for Anaerobic Methane Oxidation in a Marine Anoxic System

Microorganisms, 2020
Marine anaerobic methane oxidation (AOM) is generally assumed to be coupled to sulfate reduction, via a consortium of anaerobic methane-oxidizing archaea (ANME) and sulfate-reducing bacteria (SRB).
