Rational design of 2D/2D CS/SiC van der Waals type-II heterojunctions: a visible-light-driven photocatalyst for hydrogen production

Abstract

A hotspot in renewable energy is visible-light-driven photocatalytic water splitting for hydrogen production. Monolayer stacking in the form of van der Waals heterojunction (vdWH) can be used for band gap...

Two-dimensional g-CNs/GeC heterojunctions: desirable visible-light photocatalysts and optoelectronic devices

“…Surprisingly, 2D materials possess superior physical and chemical properties such as large surface area, short carrier migration distance and numerous active sites, which endow them with great potentials as outstanding photocatalysts. [10][11][12] In recent years, a batch of graphene-like photocatalysts have emerged, including transition metal sulfides, hexagonal boron nitride, 13,14 group IV graphene-like compounds 15,16 and carbon nitrogen compounds. [17][18][19][20] These 2D materials demonstrate excellent optical, electrical, and mechanical properties, which have been extensively researched and employed in various domains, including the field of photocatalysis.…”

Interfacial Electronic States of GeC/g‐C3N4 van der Waal Heterostructure with Promising Photocatalytic Activity via Hydrogenation

“…[36] To produce H 2 , research into novel g-C 3 N 4 -based photocatalysts with strong electron-hole separation and excellent visible light absorption is crucial. The electronic characteristics of 2D materials can be tuned using several techniques, including constructing heterostructures, [37][38][39] applying strain [40][41][42] and doping. [43] Among these, it is noteworthy that creating heterostructures has shown to be a successful approach for modifying electronic characteristics and expanding the range of applications for 2D materials.…”
