光催化甲烷氧化制含氧化合物研究进展

Research Progress of Photocatalytic Methane Oxidation to Oxygenates

甲烷是一种重要的化石燃料且广泛存在于地壳中。在化学和制药工业中,将低价值的甲烷转化为增值的化学品是有重要意义的。甲烷到有价值的化学品和燃料的转型被认作是催化领域的“圣杯”,它的C-H键本身固有的低反应活性仍然是一个主要的挑战。这篇综述讨论了在低温下光催化甲烷产生的含有氧原子的氧化物。另外,还指出甲烷的光催化氧化可能是未来的研究方向。

Methane is an important fossil fuel and widely available on the earth’s crust. The conversion of less valuable methane into value-added chemicals is of significant importance in the chemical and pharmaceutical industries. Although the transformation of methane to valuable chemicals and fuels is considered the “holy grail” in the field of catalysis, the low intrinsic reactivity of its C-H bonds is still a major challenge. This review discusses the advancements in the photocatalytic oxidation of methane at low temperatures with products containing oxygen atom(s). Additionally, the future research direction is noted that may be adopted for methane oxidation via photocatalysis at low temperatures.
