In recent years, Single-atom catalysis (SAC) has become one of the most research hot topics in heterogeneous catalysis. As it is known, both homogeneous and heterogeneous catalysts are important for the reactions used in chemical industry. In homogeneous catalysis, up to 100% of the atoms may remain active during reactions, while for the in the case of heterogeneous catalysts, only a small fraction of the metal atoms can be utilized due to the aggregation of the atoms when forming clusters. In this way, SACs have the benefits of homogeneous and heterogeneous catalysts. In our case, we will use a 2D covalent organic framework (COF), which is a π-conjugated microporous polymer with a high stability, designability and crystallinity. In addition, contains a high number of pyridinic nitrogen which will not only be used for anchoring the metal atoms, but also as an active site for the catalytic reaction[1][2][3]. Here we propose a single atom ruthenium catalysts on a 2D COF for improved electrocatalytic hydrogen evolution reaction.
