Can heterojunction engineering optimize catalytic activity and durability?

Nevertheless, the optimization of both catalytic activity and durability via heterojunction engineering remains a considerable challenge. In this work, we fabricated electrocatalysts of Co/CoO heterojunctions on a highly porous hollow carbon material.

Are heterojunctions a promising material for high-efficiency bifunctional oxygen electrocatalysts?

The authors declare no conflict of interest. Abstract Heterojunctions are a promising class of materials for high-efficiency bifunctional oxygen electrocatalysts in both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).

Are heterojunction-based electrocatalysts effective in oxidation reactions?

The heterojunction-based electrocatalysts are found not only effective for oxygen evolution reactions and hydrogen evolution reactions, but also to be very useful toward various electrochemical oxidation reactions as well as electrochemical reduction reactions involving small molecules undergoing decomposition at very low energy.

Are heterojunctions a smart approach to promoting electrocatalytic activities?

Recently, construction of heterojunctions with a combination of materials with desired band structures is considered to be a smart approach in promoting electrocatalytic activities by attaining charge redistribution and manipulating the electronic structure at the interface.

How do electrocatalysts of co/COO heterojunctions work?

In this work, we fabricated electrocatalysts of Co/CoO heterojunctions on a highly porous hollow carbon material. The formation of heterojunctions increases the abundance of accessible active sites and optimizes the electrocatalytic reaction kinetics and reactivity.
