Constructing Hierarchical 3D Co/N- Carbon Electrocatalyst for Efficient Oxygen Reduction and Overall Water Splitting

Abstract

Exploring highly efficient and multifunctional electrocatalytic material is crucial for renewable energy technologies. Herein, by studying a multidimensional and multifunctional Co/N-C catalyzer, we demonstrated that two categories of preferential characteristics for electrocatalysts, viz., activity distinctions between different reactions and feature distinctions between component and structure aspects, are not mutually exclusive yet can be well addressed simultaneously. This rationally designed and cost-effective hybrid catalyst synergically integrates the features for efficient versatile electrocatalyst including ample active species, prompt mass transport, excellent conductivity and structural stability in both acidic and alkaline electrolytes. The thus obtained multidimensional catalyst delivers excellent activities in oxygen reduction and overall water-splitting reactions in conjunction with good durability, which then enables prominent performance in a rechargeable Zn-air battery and also demonstrates the feasibility in a self-powered water-splitting unit. This study opens up new avenues for rational design and easy fabrication of multidimensional catalysts with desired performances for various renewable energy applications.
