The well-known semiconductor CdS can be transformed into an efficient, visible light photocatalyst that can selectively oxidise C-H bonds using molecular oxygen as the oxidant under ambient conditions, say scientists from China.
The team attributes the high performance to the catalyst’s cubic phase, high surface area and efficient separation of photogenerated charge carriers upon visible light irradiation. It is easy to make and could be used to activate C-H selectively to make fine chemicals, they say.
