“…[ 53–55 ] Methanol is considered to be the ideal methane conversion product due to its characteristics as an easy‐to‐transport liquid that can be utilized as both fuel and a fundamental chemical feedstock. [ 56–58 ] Conventional methane‐to‐methanol conversion follows an energy‐intensive multistep route, wherein methane is steam reformed at high temperatures to produce syngas (CO and H 2 ). The syngas is then utilized to synthesize methanol under high pressure.…”

Methane as the main component in natural gas is a promising chemical raw material for synthesizing value‐added chemicals, but its harsh chemical conversion process often causes severe energy and environment concerns. Photocatalysis provides an attractive path to active and convert methane into various products under mild conditions with clean and sustainable solar energy, although many challenges remain at present. In this review, recent advances in photocatalytic methane conversion are systematically summarized. As the basis of methane conversion, the activation of methane is first elucidated from the structural basis and activation path of methane molecules. The study is committed to categorizing and elucidating the research progress and the laws of the intricate methane conversion reactions according to the target products, including photocatalytic methane partial oxidation, reforming, coupling, combustion, and functionalization. Advanced photocatalytic reactor designs are also designed to enrich the options and reliability of photocatalytic methane conversion performance evaluation. The challenges and prospects of photocatalytic methane conversion are also discussed, which in turn offers guidelines for methane‐conversion‐related photocatalyst exploration, reaction mechanism investigation, and advanced photoreactor design.

“…Although many great advances in the field of heterogeneous catalysis have been reported, 8 these types of catalysis frequently required harsh reaction conditions for methane oxidation, which lead to low methanol yields caused by overoxidation. 9−16 In nature, some methanotrophs have evolved the enzyme methane monooxygenase (MMO), which can catalyze the direct hydroxylation of methane to methanol under mild conditions.…”

Biological methane oxidation is a highly desirable method for the conversion of natural gas into a liquid to meet the increasing demand for fuel and chemical feedstock as well as reducing the potent greenhouse effects of methane emissions. Because natural hemoenzymes that can catalyze the conversion of methane to methanol have not been found, it has long been considered that hemoenzymes, including cytochrome P450s (P450s), cannot catalyze the oxidative conversion of methane. Herein, we report the catalytic oxidation of methane by wild-type P450BM3, without any mutagenesis, in the presence of chemically evolved dummy substrates (decoy molecules) under high-pressure methane at 10 MPa. Our studies showed that methane was catalytically converted into methanol at room temperature with a total turnover number of 4.

“…With increasing attention devoted to data-driven catalyst investigation, the conventional DFT goal has shifted from understanding to discovering catalysts, leading to the next idea for catalyst design. 27,28 The cost of DFT processing remains high, but DFT for screening catalysts 29,30 is also proving to be a powerful tool for the next style of catalyst design. By virtue of the development of innovative technologies such as quantum computing, computational simulation can again be a game changer in the field of materials science.…”
