The invention relates to electrocatalysts comprising a carbonitride (CN) shell featuring good electrical conductivity, coordinating suitable catalytically active sites. In a preferred aspect of the invention, the aforesaid carbonitride shell coordinates nanoparticles or aggregates of nanoparticles, on which the active sites of the electrocatalyst are located. In a preferred form of the invention, said carbonitride shell covers suitable cores with good electrical conductivity. Said electrocatalysts are obtained through a process involving the pyrolysis of suitable precursors; in one aspect of the invention, the preparation process requires certain further steps. In one preferred aspect, the steps comprise one or more of the following: chemical treatments; electrochemical treatments; further pyrolysis processes.
