英文摘要Cordinatively unsaturated ferrous(CUF)sites confined in nanosized matrices are active centers in a wide range of enzyme and homogeneous catalytic reactions.Preparation of analogous active sites at supported catalysts is of great significance in heterogeneous catalysis but remains a challenge. Based on surface science measuraments and density functional calculations,we show that interface confinement effect could be utilized to stabilize the CUF sites by talking advantage of strong adhesion between ferrous oxides and metal substrates. The interface confined CUF sites together with the metal supports are active for O2 activation, producing reactive dissociated O atoms. We show that the unique structural emsemble was highly efficient for CO oxidation at low temperature under typical operating conditions of a proton exchange membrane fuel cell.
