Heterogenized non‐noble metal‐based catalysts allow for cost‐efficient and environmentally benign hydrogenations. Here, we have developed a straightforward reductive amination methodology using molecular hydrogen in the presence of a Co 3 O 4 /NGr@C catalyst system. Various carbonyl compounds were transformed with secondary amines to the corresponding tertiary amines with good to excellent yields and selectivity. The Co 3 O 4 /NGr@C catalyst is recycled up to five times without significant loss of activity.
