Abstract

Local structures around copper oxides (CuOx) supported on aluminum oxide borates (10A2B) during the NH3 combustion reaction were studied by operando XAFS. Although CuOx in as-prepared CuOx/10A2B at room temperature can be assigned to CuO, the CuO was partly reduced to Cu2O during NH3 combustion at 400°C. In contrast, CuAl2O4 was formed after thermal aging of CuOx/10A2B at 900°C for 100 h in air, local structures of which were preserved during NH3 combustion at 600°C.
