摘要：

The Heterogenized Ru (III) catalyst is synthesized via immobilizing molecular RuCl3 on a pyridine-functionalized covalent triazine framework (PY-CTF). The N sites in the PY-CTF support effectively donate electrons to the Ru (III), resulting in a catalyst with favorable catalytic activity. The as-synthesized RuCl3@PY-CTF catalyst exhibits a high turnover number (TON) of 2067 in 2 h for the hydrogenation of CO2 to formate. In this reaction, triethylamine (TEA), tripropylamine (TPA), and triethanolamine (TEOA) are respectively employed as basic mediums. Among them, TEA demonstrates the highest promoting effect due to its greater contribution to the cleavage of H2, optimal interaction with CO2, and higher polarity of the HTEA-HCOO adduct, as determined by density functional theory (DFT) calculations.
