An Ir-incorporated cobalt hydroxide electrodeposited on titanium meshes (Ir@Co(OH)₂/TM) is developed to achieve efficient removal of nitrogen-containing pollutants, while simultaneously synthesizing high-value ammonia and aromatic amines.

An architecture engineering strategy is developed to construct h-NCNWs which enable the uniform deposition of ultrafine Rh NPs. The resultant Rh/h-NCNWs exhibit excellent H₂ production performance with a TOF of 1234 min⁻¹ for AB hydrolysis.
