Abstract:
Here, a nanocomposite of crystalline CoWO-/amorphous Co-B heterostructure and N-doped
multiwalled carbon nanotube@reduced graphene oxide nanoribbons (c-CowO4a-coB@N-doped
MWCNT@rGNRs) was prepared by annealing a mixture of dicyandiamide and multiwalled carbon
nanotube@grapheneoxide nanoribbon via a one-step calcination, followed by supporting crystalline
CoWO4amorphous Co-B heterostructure particles and exhibited a high-performance ORR electrocatalyst.
The ribbon-like structure and nitrogen surface state of the N-doped MWCNT@rGNR matrix can effectively
control the uniform distribution of c-CoWO4'a-CoB particles and improve the electrocatalytic performance of
the electrocatalyst. The prepared c-CoWO4a-CoB@N-doped MWCNT@rGNR compositeelectrocatalyst
material containing the c-CoWO4'a-CoB content of 20 wt%, exhibits a high ORR electrocatalytic activity with
a mass-normalized current density of 2.69 and 1.07 times those of N-doped MWCNT@rGNRs and c-
CoWO4a-CoB, respectively. The N-doped MWCNT@rGNRs facilitate the dispersion of the c-CoWO4/a-
CoB heterostructure particles, maximize the exposure of active sites on the surface, and improve the
electrocatalytic activity of ORR. Consequently, the obtained c-CoWO4/a-CoB particles supported on N-doped
MWCNT@rGNR .nanocomposite might be a promising non-platinum electrocatalyst with low cost and high
efficiency in electrocatalyst applications for fuel cells
