Abstract
X-Ray absorption spectra show that a CeO(2)-supported CO oxidation catalyst prepared from Au(III)(CH(3))(2)(C(5)H(7)O(2)) initially incorporated Au(III) complexes that were catalytically active at 353 K; during operation in a flow reactor, the gold aggregated into clusters and the catalytic activity increased.
摘要
X射线吸收光谱表明，由Au(III)(CH(3))(2)(C(5)H(7)O(2))制备的CeO(2)负载的CO氧化催化剂最初含有在353 K时具有催化活性的Au(III)配合物；在流动反应器中运行期间，金聚集成团簇，催化活性增加。
