Photocatalytic conversion of methane to ethane suffers from low yields due to poor selectivity and quantum efficiency. Now, ethane is produced by a photochemical looping strategy using a nanocomposite of titanium dioxide, phosphotungstic acid and silver cations, with selectivity of 90% and quantum efficiency of 3.5% at 362 nm.

由于差的选择性和量子效率，甲烷向乙烷的光催化转化具有低产率。现在，乙烷是通过光化学环化策略使用二氧化钛，磷钨酸和银阳离子的纳米复合材料生产的，在362 nm处的选择性为90％，量子效率为3.5％。
