研究了不同活性炭负载铂催化剂在十氢萘脱氢反应中的催化性能。有机氢化物作为贮氢介质，在温和条件下催化脱氢反应迅速进行，是燃料电池的有效氢源。其中，十氢萘在本研究中的选择是由于分析的简单性，以及与文献报道的工作进行比较，铂负载量，十氢萘/催化剂的比例和温度是已知的影响十氢萘转化为氢气的最重要的参数。最佳的Pt负载量和十氢萘/催化剂的比例分别在4wt%PVC和2.7 ml/g，表现出高的十氢萘转化率（约60%）和合适的反应速率。(c)2007年国际氢能协会。由爱思唯尔有限公司出版。保留所有权利。
Different platinum catalysts supported on activated carbon have been investigated for decalin dehydrogenation under several reaction conditions. Organic hydride as hydrogen storage media is an efficient source for fuel cells when the catalytic dehydrogenation reaction occurs rapidly under mild conditions. Among hydrides, the choice of decalin in this study is owed to the simplicity of analyses, as well as comparison with works reported in literature.Platinum load, decalin/catalyst ratio and temperature are the most important parameters known to influence decalin conversion to hydrogen. Optimal Pt loading and decalin/catalyst ratio were observed at 4 wt% PVC and 2.7 ml/g, respectively, exhibiting high decalin conversion (approximately 60%) and a suitable reaction rate.
