CoO–CoSe2@N-CNTs/rGO was prepared via a two-stage calcination followed by a partial selenization process as described in Scheme 1. Briefly, in the first-stage calcination of dicyandiamide and CoCl2 at 550°C under N2 protective atmosphere, dicyandiamide experienced thermal condensation to give the polymeric graphitic-carbon nitride (g-C3N4) [47]. The g-C3N4 offered plentiful pyridine-like N that held abundant lone-pair electrons to coordinate Co2+ [48]. It should be pointed out that g-C3N4

Constructing CoO–CoSe2 heterostructures through partial selenization of CoO is proposed to ameliorate the electrocatalytic performance of Co-based compounds toward oxygen evolution reaction (OER). Moreover, with reduced graphene oxide as a platform to in-situ grow N-doped bamboo-like carbon nanotubes encapsulating part of CoO and CoSe2 nanoparticles, we fabricated a novel hybrid (denoted as CoO–CoSe2@N-CNTs/rGO) via a combination of two-stage calcination and subsequent selenization treatment. As an OER electrocatalyst in 1.0 M KOH, CoO–CoSe2...
