Comparison of Properties of Nafion- and Nanocellulose-Bonded Powder Catalysts

(A) Photos of N-Mo₂C aqueous dispersion with nanocelluloses and Nafion solutions, respectively.

(B) The LSV curves (without iR corrected) of N-Mo₂C@Nafion, N-Mo₂C@NCs, 20 wt% Pt/C@Nafion, and 20 wt% Pt/C@NCs.

(C and D) (C) Plot of positive and negative current density differences at a given potential (0.15 V versus the RHE) against the CV scan rates, and (D) EIS Nyquist plots at −200 mV versus RHE recorded of porous N-Mo₂C@Nafion and N-Mo₂C@NCs.

(E and F) (E) EIS Nyquist plots with different overpotentials and (F) the chronoamperometry curves recorded at the overpotentials of 250 and 320 mV driven from N-Mo₂C@NCs. All electrochemical tests were performed in 0.5 M H₂SO₄ solution.
