Description of the research topic:
One of the cheapest methods is the liquid phase exfoliation (LPE) process that provides high yield of nanoflakes considering the practical applications and mass productions of 2D nanomaterials. Unfortunately, the photoelectrochemical activity and energy conversion efficiency of LPE prepared nanoflakes are typically much lower than those of bulk/single crystal electrodes. The proposed project aims to resolve an important problem in photoelectrochemistry connected to defects and their roles in renewable energy conversion and storage processes.
We will prepare two-dimensional nanostructures with catalytic centres, to understand their electronic and structural properties unraveling the role of defects. We will deposit either activating or passivating agents on the 2D nanosheets to distinguish their role in the photoelectrochemical processes, for CO2 reduction reaction. The main research objective is to determine whether i) passivation of trap states, ii) activation of catalytic active centres, iii) or both are required to improve the photoelectrochemical activity.
