This mini-review summarizes a variety of experimentally identified reactions in the activation and transformation of CO_(2) by metal species in the gas phase. The use of advanced mass spectrometric instrumentation in conjunction with quantum chemistry calculations can uncover the mechanistic details and determine the vital factors that control the activation of CO_(2). This review focuses mainly on three topics: the activation of CO_(2) by(1) bare metal ions and metal oxide species,(2) metal hydrides, and(3) other gas-phase metal species. Emphasis is placed on the latest advances in the hydrogenation of CO_(2) mediated with metal hydrides. A potential prospect toward the future effort in the activation and transformation of CO_(2) in gas phase has also been discussed.展开更多
