- Abstract
The precise control of electronic configurations of catalytic sites via molecular engineering is significantly desirable for boosting electrocatalytic activity. We reported a new‐type composite electrocatalyst with cobalt phthalocyanine supported on N‐doped MXene nanosheets (N‐MXene/CoPc) through a self‐assembly process. Beneficial from the joint action of N sites participation and axial coordination, N‐MXene/CoPc exhibits a high ORR activity with positive onset potential (Eonset=0.98 V vs. RHE) and half‐wave potential (E1/2=0.863 V), which is superior over the pristine CoPc (E1/2=0.72 V) and the composite with undoped MXene as support (MXene/CoPc, E1/2=0.771 V). Additionally, N‐MXene/CoPc exhibits an excellent durability with only 8.5 % attenuation after 25000 s of continuous i‐t test, while a more obvious decay 18.6 % for 20 wt.% Pt/C. This work not merely reported a robust ORR catalyst, but more provides a reasonable design strategy for nonnoble‐metal catalysts through catalyst‐support interactions.
