Abstract

Heterojunctions typically consist of two semiconductor materials in close contact or one metallic nanostructure in contact with a semiconductor. On the other hand, two-dimensional (2D) materials manifest as sheets with remarkably low thicknesses. Many 2D materials have high electrical conductivity and surface area, along with the potential for functionalization to enhance performance across various applications. This paper elucidates key features, properties, and applications of both heterojunctions and 2D materials. Specifically, it underscores the advantages of these materials in hydrogen production, photodegradation of persistent pollutants, and the generation of small molecules through CO2 photoreduction in the presence of solar irradiation.
