Highly selective and robust single-atom catalyst Ru₁/NC for reductive amination of aldehydes/ketones.

ABSTRACT: Single-atom catalysts (SACs) have emerged as a frontier in heterogeneous catalysis due to the well-defined active site structure and the maximized metal atom utilization. Nevertheless, the robustness of SACs remains a critical concern for practical applications. Herein, we report a highly active, selective and robust Ru SAC which was synthesized by pyrolysis of ruthenium acetylacetonate and N/C precursors at 900 °C in N₂ followed by treatment at 800 °C in NH₃. The resultant Ru₁-N₃ structure exhibits moderate capability for hydrogen activation even in excess NH₃, which enables the effective modulation between transimination and hydrogenation activity in the reductive amination of aldehydes/ketones towards primary amines. As a consequenc
