中文摘要	the co oxidation is very important of practical application for the control of environmental pollution, the purification of industrial emissions, and the co preferential oxidation in fuel cell. hopcalite catalysts (mainly composed of mnox and cuo) and supported pt, pd, ru, rh catalysts are two kinds of important catalysts for co oxidation. however, all of them have high activity only at relatively high temperature. since the exciting finding by haruta and co-workers [1] that supported gold catalysts with high activity even at temperature below 0 oc, various au-containing catalysts has been investigated and found to be active for low-temperature co oxidation. however, most of them exhibit very poor stability at anti-sintering. therefore, searching for new catalysts which have both excellent activity and ultra stability becomes one important task. to achieve this aim, many approaches have been conducted by many groups, for example, using the mixed oxide as support, modifying the support surface by po43-, no3-, so42- or developing new supports like metal phosphate. these approaches, to some degree, improved the stability of the catalysts to resist sintering at high temperature, but actually made them more easily deactive on stream. here, we report one kind of novel hydroxyapatite (hap)-based catalyst, au/fexoyhap, which not only exhibits high activity even after 400 oc sintered, but also very stable on stream.
