| Abstract Scope |
Electrocatalysts are critical to increase reaction rates and control selectivity in many electrochemical reaction. Rational design and synthesis of material with controlled structures and morphologies from nanoscale to microscale are of utmost importance in order to achieve optimal performances. Going beyond traditional noble metals such as gold and platinum, we shall like to report on a new generation of 0D, 1D and 2D nanocomposites for water splitting and beyond.
As a part of this electrochemical system strongly depends on the catalyst support. We further show that the formation of hybrid core-shell nanostructures utilizing carbon materials and metal foams as a base template effectively enhance the performance and extend the range of applications. For example, MoS2/MoO2 or even VO3/VS2 coated graphene/carbon nanotubes formed excellent catalytical activity in the hydrogen evolution reaction. |
