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.

Can heterojunction engineering improve electrocatalyst performance?

However, the most active electrocatalysts show orders of magnitude lower performance in alkaline electrolytes than that in acidic ones. To improve such catalysts, heterojunction engineering has been exploited as the most efficient strategy to overcome the activity limitations of the single component in the catalyst.

Can -conjugated ligands improve energy level alignment at 2D/3D heterojunctions?

These π-conjugated ligands provide an opportunity for manipulating energy level alignment at 2D/3D heterojunctions through rational design of organic cations, thereby allowing more efficient hole extraction and reducing interface charge accumulation (18).

What is a heterojunction in chemistry?

A heterojunction is defined as the interface field formed by the contact of two different semiconductors. Nowadays, heterojunctions have extended from semiconductor-semiconductor (p-n) heterojunctions to metal-semiconductor (Schottky) heterojunctions and atypical semiconductor and ionic conductor heterostructures [ 27 ].

Why is heterojunction important?

The different components of the heterojunction can introduce new adsorption sites, so the rational design of the heterojunction can not only improve the performance of the catalyst, but also break the linear relationship of the adsorption energy, leading to excellent catalytic performance. 3. Catalysts for Alkaline the HER 3.1. Pioneering Design

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.
