The OSRM reaction over gold promoted copper zinc catalyst

摘要

Hydrogen production by oxidative steam reforming of methanol (OSRM) was investigated over CuOZnO-based catalysts promoted by Au, which were prepared by using co-precipitation and deposition-precipitation and were characterized by X-ray powder diffraction (XRD), H₂-temperature programmed reduction (TPR), induced coupled plasma mass analyzer (ICP-MS), and transmission electron microscopy (TEM). We found that the reducibility of CuOZnO-based catalyst could be improved with increasing Au loading, which induced better performance at temperatures lower than 200°C. In addition, through calcination pretreatment, the residual chloride on the catalyst could be removed, which might expose more Au on the surface and result in a decrement of CO selectivity.View full textDownload full textKeywordsOSRM, gold, promoter, CuOZnO-based catalyst, calcinationsRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/02533839.2011.552962
