Our earlier experimental study has shown that exhaust unburnt hydrocarbon emissions from spark-ignition engines can be reduced effectively by using in-cylinder catalysts on the surface of the piston ...

This study is led by Prof. Yuchao Zhang (Key Laboratory of Photochemistry, Chinese Academy of Sciences). Photoelectrochemical (PEC) water oxidation reaction has attracted considerable attention in ...

UV light initiates an oxidation process that fragments a water-dispersible form of graphene and eventually decomposes the material, as indicated by the gradual lightening of the solutions shown here..
