How to develop high-efficient and low-cost electrocatalysts for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is urgent in fuel cell and metal-air batteries. What we are going to introduce is how to improve the performance of catalyst for ORR and OER under different acid treatment conditions. Spinel NiCo2O4 and carbon nanotubes (NC-0) composites have been synthesized via a facile hydrothermal method without using high temperature and the result samples were treated using nitric acid for 1h, 2h and 3h which are named NC-x (x=1,2 and 3) respectively. Comparing the untreated composite (NC-0) with NC-3, the ORR current density is increased from 2.1 mA / cm2 to 4.2 mA / cm2 and OER current density is reduced from 13.3 mA / cm2 to 8.0 mA / cm2. The result would enlighten and promote directional synthesis of different performance electrochemical catalyst.
