The environmental issues caused by the consumption of fossil fuels and their abridged reserves have led to an urgent demand for the extensive use of sustainable and clean energy resources. In this context, photocatalysis and electrocatalysis are two crucial renewable and sustainable technologies to overcome the global energy crisis in clean ways. The main challenges of these two techniques are seeking high-efficiency, low-cost and stable catalysts. The efficiency of photo- and electrocatalysts is directly related to the design of inexpensive catalysts with optimal structures.
2D-Carbon-based heterostructures are found to be promising electrocatalysts and photocatalysts. Compared to 2D Carbon-Based materials, they have higher exposed active surface, tunable structural and electronic properties, promising stability, high electrical conductivity, synergistic and heterointerface effects. Most of the 2D carbon-based materials have low structural stability and poor-catalytic activity due to their slow electron transfer rate and anisotropy. 2D materials also suffer from chemical or structural changes under sunlight or electric field, which consequently lowers catalytic activity. Furthermore, the reaction rate constant at the edges of 2D materials is higher compared to the basal plane owing to the less available active sites at the basal plane. All the above-mentioned characteristics of individual 2D carbon-based materials in terms of catalytic performance, designing of 2D carbon-based heterostructures by combining with 0D, 1D, 2D or 3D components is now a trend in the field of catalyst.
Constructing heterostructures is highly beneficial towards the exploration of catalytic studies as it allows tailoring electronic properties, improving strength and durability and controlling the structure and properties at the interface, allowing synergistic effects and maximized exposure of active sites.
