英文摘要: Boron trioxide (B 2 O 3 ), a common and easily available boron oxide, was first reported as an effective metal-free heterogeneous catalyst for the chemical fixation of CO 2 with epoxides to produce cyclic organic carbonates (COCs). The ball-milling treatment of B 2 O 3 significantly enhanced the catalytic activity by increasing the adsorption capacity to propylene oxide substrate. In situ DRIFTS characterization indicated there was a ring opening process of epoxides on the surface of B 2 O 3 , which was induced by the boron sites from B 2 O 3 . The recovery test of B 2 O 3 showed that it could be easily recycled and reused for 5 runs without a loss of activity. This kind of Lewis acid catalytic property of B 2 O 3 marks a rare case of a metal-free heterogeneous catalyst mimicking the metal-based catalysts for the COCs production. © 2018 Elsevier Ltd.
