hotoelectrochemical technique has attracted tremendous attentions since it combined merits of both optical and
electrochemical methods, which has been applied as efficient strategy to develop DNA sensor, cytosensing, enzymatic
analysis, immunoassay and many other small molecules sensing etc. The mechanism of photoelectrochemical sensor is
based on reductive property of photoelectron or oxidative capacity of photo-generated hole. Howbeit, efficient and stable
photocatalyst that are capable of harvesting visible light for an optimized use of solar energy are still very prerequisite. In order
to best facilitate the specific analytical system, in our group, through theoretical simulations with calculation of the binding
energies, a variety of semiconductor and composite materials have been designed and optimized including silver halide series
of composites (AgBr/g-C

monitoring & purification, global antioxidant capacity assessment, o-diphenol discrimination, carbon dioxide reduction and
other applications. It is anticipated that the photoelectrochemical technique will open up new insights into the architectural
design of novel photocatalysts with high photoactivity and further utilizations in the environmental, food and energy field.
