应用正电子湮灭伽马的角相关关系研究了离子交换过程改变NaHY沸石催化剂的酸性。Brønsted酸度随样品角相关谱线形参数呈线性变化。
Angular correlations of positron annihilation gammas were applied to study NaHY zeolite catalysts whose acidity was altered by an ion-exchange process. The Brønsted acidity was found to vary linearly with the lineshape parameter of the angular correlation spectrum of the sample.
