“…De Jong's group developed a 13X zeolite confined Ni catalyst for CO 2 methanation and CeO 2 was added as promoter. [ 94 ] CeO 2 assisted in the dispersion of Ni species but the isolated atoms were not specified according to the energy dispersive X‐ray spectroscopy (EDX). TPR indicated strong H‐spillover effect of Ni and reduction of CeO 2 ( Figure ).…”

CO2 emission has been an international issue of great concern. Utilizing of CO2, especially converting it to value‐added products, is widely investigated, among which the thermal conversion of CO2 has enormous potential for industry. Researches on single‐atom site catalysis (SAC) have become increasingly systematic during the last years. High performance and distinctive selectivity that SAC exhibits attribute to the isolated structure a large extent. To understand the structure–performance relationship of SAC in CO2 activation, issues including substrate, active components, coordination, chemical structure, etc. are of the essence not only in academia but also in industry. However, it is far away from the vision that the synthetic procedure and reaction pathway are deeply comprehended, thereupon precise single‐atom sites with specific structure are constructed and elementary reactions are regulated at will. Still a lot of efforts are needed to this field. Herein, CO2 reduction reactions are reviewed according to the products, and then catalysts are introduced by the substrate. The promoter, stability, synthesis/regeneration, characterization, and theory calculation issue related to SAC and CO2 activation are comprehensively summarized and discussed. Looking back the progress, challenge and outlook of single‐atom site catalysis are also proposed.

“…In most cases, the solely catalytic active metals are deposited on a support and combined with various promoters to achieve higher activity [31][32][33][34][35]. Metal oxides such as Al 2 O 3 , SiO 2 , CeO 2 , TiO 2 , or ZrO 2 are most commonly used as support.…”

In this context, coupling of methanation with small, decentralized CO 2 sources such as biogas plants provides one possibility. However, fluctuating availability of renewables for hydrogen production in combination with small storage volumes result in an enhanced demand for dynamic process operation. This leads to new research challenges with respect to the required catalysts and the overall process design. To draw reliable conclusions about the catalytic performance under dynamic process operation, the mechanism of the methanation reaction as well as typical deactivation procedures of the catalyst applied under steady-state conditions have to be reviewed thoroughly.
