@article { , title = {CO preferential oxidation in a novel Au@ZrO₂ flow-through catalytic membrane reactor with high stability and efficiency}, abstract = {CO preferential oxidation (CO-PROX) achieves much interest as a strategy to remove trace CO in reformed gases for hydrogen utilization. Herein, we reported a novel Au@ZrO₂ catalytic membrane reactor by embedding gold nano-particles in ZrO₂ hollow fiber membrane for CO-PROX. The flow-through catalytic membrane exhibited high catalytic activity and oxygen selectivity, which gave a turnover frequency of 4.73 s⁻¹ at 60 °C, 2–3 times higher than conventional catalyst pellets. CO conversion of >95\% was achieved over the catalytic membrane, which maintained great operational stability during 500-h operation even CO₂ and H₂O were added in the feed stream. The excellent catalytic performance of the flow-through catalytic membrane makes gold catalyst possible for practical application in the removal of CO from hydrogen.}, doi = {10.1016/j.ijhydene.2016.05.210}, eissn = {0360-3199}, issn = {0360-3199}, issue = {31}, journal = {International journal of hydrogen energy}, pages = {13513-13520}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://hull-repository.worktribe.com/output/448059}, volume = {41}, keyword = {Specialist Research - Other, Catalytic membrane reactor, Gold nano-particle, Hollow fiber, CO preferential oxidation, H₂ purification}, year = {2016}, author = {Zhu, Feng and Zhang, Yuting and Gu, Xuehong and Chen, Changlin and Jin, Wanqin and Ke, Xuebin} }
