摘要：

The coupling selectivity was greatly enhanced by adding Li to La2O3, compared with the single La2O3. The O2- species was found on the Li/La2O3 but not on the single La2O3. In low-temperature desorption, ethane desorbed from the Li/La2O3 but was not detected with the single La2O3. It is considered that the addition of Li gave rise to some basic sites which are favorable for the coupling reaction.
