2D/2D layered nano-heterostructures of transition metal dichalcogenides (MS2, M = Mo, Sn) and graphitic carbon nitride (g-C3N4) for photocatalytic hydrogen production and environmental remediation

Abstract

Highly efficient and cost-effective photocatalysts are among the most prominent targets in the field of clean energy production and environmental remediation. To understand the photochemical charge transfer mechanisms at the nanoscale, it is essential to develop highly effective catalysts. This dissertation focuses on the successful development of a new synthetic strategy for preparing 2D/2D layered nano-heterostructures of transition metal dichalcogenides (MS2, M = Mo, Sn) and graphitic carbon nitride (g-C3N4) for photocatalytic fuel production and environmental remediation applications. In this context, the rational design of new photochemical systems has led us to the synthesis of layered heterostructures by depositing MoS2 nanosheets with variable lateral sizes on the surface of g-C3N4. These composite structures were studied as cathodic catalysts for photocatalytic generation of hydrogen from water under UV and visible light irradiation. In general, the photochemical water splitti ...
