class="label">•: A simple and rapid method of the exfoliation/restacking route was adopted to fabricate α-ZrP/CoTMPyP laminar nanocomposite.
class="label">•: The zeta potential value of α-ZrP colloidal dispersion was −40.1 mV, indicating that the colloidal dispersion was stable and well dispersed.
class="label">•: The excellent electrocatalytic performance of α-ZrP/CoTMPyP hybrid film on oxygen reduction with the reduction peak potential shifting from −0.692 V (bare glass carbon electrode) to −0.203 V (modified electrode).
class="label">•: The results of electrochemical measurements indicated that oxygen was reduced to H2O2 via two-electron transfer.
