Operando spectroscopy of catalysts is important for understanding reaction mechanism of heterogeneous catalysis. In this presentation, our recent AP-XPS studies on activation and hydrogenation of carbon dioxide on copper-based model catalysts will be discussed as well as experimental detalis and future perspective.
