CoTe nanoparticle-embedded N-doped hollow carbon polyhedron: an efficient catalyst for H2O2 electrosynthesis in acidic media

CoTe nanoparticles embedded nitrogen-doped hollow carbon polyhedron (CoTe@NC) acts as a highly efficient 2e − O 2 reduction reaction electrocatalyst with a high selectivity of up to 92.6% at 0.3 V, significantly outperforming CoTe and NC counterparts.
