Electric double layer structure at metal/water interface

Electrified solid/liquid interfaces are the key to many physicochemical processes in a myriad of areas including electrochemistry and colloid science. With tremendous efforts devoted to this topic, it is unexpected that molecular-level understanding of electric double layers is still lacking.


Semiconductor Introduction

Semiconductor/electrolyte interface is at the heart of our understanding of electrocatalysis, photocatalysis and electrophotocatalysis. Both the nature of interfacial reaction and the structure of electric triple layers(ETL) dictate the chemistry and the physics of electrified interfaces.


Phase transition catalysis of dynamical catalysts

Heterogeneous catalysis exhibit highly dynamic effects under reaction conditions, the dynamical evolution of catalyst structures has a quite great impact on catalytic performances. However, traditional theoretical studies just taken account to the most stable structures of catalysts, ignoring the structural dynamic effect of catalysts.


Battery Materials Introduction

Electrochemistry of highly concentrated electrolytes. NMR simulation and dynamics of electrode. Calculating properties of solid-state electrolytes based on machine learning potentials. Physical chemistry and solvation effect of differently concentrated aqueous electrolyte. Large scale simulation of electrode/polymer electrolyte interfaces. Free energy calculation based on machine learning potentials.


Experiments Introduction

Our research aims at understanding photo-/electrochemical interface. We grow single crystal oxide thin films by pulsed laser deposition (PLD), and study oxides-liquid interface at atomic level using X-ray photoelectron spectroscopy (XPS), atomic absorption spectroscopy (XAS) and electrochemical scanning tunneling microscopy (EC-STM).
