首次发现了GaN在烷烃无氧脱氢芳构化反应中的热催化活性。从实验和理论上研究了催化剂活性的来源。具有纤锌矿晶体结构的商用GaN粉末在高温下高选择性地将甲烷、丙烷、正丁烷、正己烷和环己烷等低碳烷烃转化为苯，表现出良好的稳定性和反应性。该催化剂非常坚固，可以重复使用，不会出现明显的失活。
The thermal catalytic activity of GaN in non-oxidative alkane dehydroaromatization has been discovered for the first time. The origin of the catalytic activity was studied experimentally and theoretically. Commercially available GaN powders with a wurtzite crystal structure showed superior stability and reactivity for converting light alkanes, including methane, propane, n-butane, n-hexane and cyclohexane into benzene at an elevated temperature with high selectivity. The catalyst is highly robust and can be used repeatedly without noticeable deactivation.
