摘要： Disclosed herein are a platinum-based catalyst for oxidation/reduction reactions and the use thereof. The platinum-based catalyst is prepared by loading a catalyst composition comprising a water soluble salt of at least one metal selected from among cerium (Ce), zirconium (Zr) and rhenium (Re), on a support comprising at least one selected from among alumina, silica and titania. The disclosed catalyst can be prepared in a simple manner without any particular limitation as to the kind of usable water soluble platinum salt, and when it is applied to various oxidation reactions, including water gas shift reactions of carbon monoxide, three-way catalytic reactions, and selective oxidation reactions of carbon monoxide, and to reduction reactions, such as reactions of removing nitrogen oxide (NOx), it will show excellent catalytic activity. In particular, the disclosed catalyst shows excellent performance even in a specific temperature range in which it is difficult to apply the prior high-temperature water gas shift reaction catalyst and low-temperature water gas shift reaction catalyst. Also, it can remove carbon monoxide even at high temperatures without the loss of hydrogen caused by methanataion, and thus is particularly useful in a hydrogen production process of producing high-purity hydrogen for fuel cells.
摘要翻译：本文公开了用于氧化/还原反应的铂基催化剂及其用途。通过将包含选自铈（Ce），锆（Zr）和铼（Re））的至少一种金属的水溶性盐的催化剂组合物载载在包含选自下列的至少一种的载体上来制备铂基催化剂：氧化铝，二氧化硅和二氧化钛。所公开的催化剂可以以简单的方式制备，对可用的水溶性铂盐的种类没有特别限制，并且当它被应用于各种氧化反应时，包括一氧化碳的水煤气变换反应，三元催化反应，和一氧化碳的选择性氧化反应，以及还原反应，如去除氮氧化物（NOx）的反应，将显示出优异的催化活性。特别地，所公开的催化剂即使在难以应用现有的高温水煤气变换反应催化剂和低温水煤气变换反应催化剂的特定温度范围内也显示出优异的性能。此外，即使在高温下也可以除去一氧化碳，而不会由于甲烷化引起的氢损失，因此特别适用于制造用于燃料电池的高纯度氢气的氢气生产方法。
