通过程序升温还原技术研究了非等温还原条件下 IrO2 和 TiO2（锐钛矿）之间的相互作用。 根据高分辨率透射电子显微镜 (HRTEM) 测定，IrO2 簇的尺寸在 0.5 至 0.9 nm 之间。

2023年1月31日 · The interaction between IrO2 and TiO2 (anatase) in non-isothermal reduction conditions has been studied by the temperature programmed reduction technique. IrO2 …

2022年12月30日 · The TPR profile was measured in a plug-flow fixed-bed reactor in 10 vol-% H 2 in Ar (50 mL min −1) at a heating rate of 10 °C min −1. The H 2 consumption was measured …

IrO2 clusters are of sizes between 0.5 and 0.9 nm as determined from High Resolution Transmission Electron Microscopy (HRTEM). Largely, two main regions for reduction were …

2007年6月30日 · The reduction of various iron oxides in hydrogen and carbon monoxide atmospheres has been investigated by temperature programmed reduction (TPR H2 and TPR …

The first region is attributed to the partial reduction of IrO2 clusters, while the second one is due to reduction of the formed crystalline (rutile IrO2), during TPR, to Ir metal. Two...

2022年2月12日 · Based on the results of H 2-TPR measurement, we convinced that the strong interaction between IrO 2 species and V 2 O 5 support is successfully constructed. XPS was …
