Developing efficient and low-cost technologies for energy conversion and storage is one of the most important scientific challenges today. The Lian group’s research program is focused on advancing the fundamental understanding of interfacial structure and dynamics that governs charge transport and energy conversion in these devices. These fundamental advances are essential to the rational improvement of existing approaches and the development of novel energy conversion concepts.
The Lian group develops and applies state-of-the-art ultrafast and nonlinear spectroscopy techniques for the study of these interfacial dynamics in situ under photocatalytic, photoelectrochemical and electrocatalytic conditions (see the Technique page for details).
These techniques are applied in the following ongoing research projects
2.Mechanisms of Long-Distance Charge Separation and Light Driven H2 Generation in Nano-heterostructures
a) Scheme of artificial solar-to-H2 conversion systems based on low-dimensional colloidal nanocrystals. HT and ET: hole and electron transfer, respectively. (b) Exciton dissociation and light-driven H2 generation in nanoplatelet-metal heterostructures.
