In many multi-step catalytic reactions, it is often difficult to find a single catalyst to optimize the energy levels of all reaction intermediates involved. Two or more types of catalytic atoms are therefore preferred which can synergistically activate the reactions and lower the energy barriers, leading to high catalytic efficiency and reduced energy consumption. This project will investigate 2D materials-based heterostructures, such as graphene and layered double hydroxides, to improve their catalytic performance for green hydrogen generation and CO2 reduction. The synthesized heterostructure will preferentially have combined electronic and chemical properties from constituent 2D materials, which can be tailored for different reactions. Surface and interfacial engineering techniques will also be applied to increase the activity and stability of the heterostructure.

 The project will include the following activities:

• Synthesize 2D materials-based heterostructures with controllable structural features and electronic properties.
• Application and optimization of 2D materials-based heterostructures in hydrogen generation and CO2 reduction.
• Understand the structure-property relationship for 2D materials-based heterostructures for hydrogen generation and CO2 reduction.
