The copper-catalyzed azide-alkyne cycloaddition reaction is a representative example of click chemistry, which proceeds with high regioselectivity when terminal alkynes are used and provides 1,2,3-tri-azoles with 100% atom efficiency. This important reaction has attracted a considerable amount of attention in organic synthesis, medicinal chemist...

Semiconductor photocatalysis has been considered to be a potentially promising approach to solve energy and environment problems with abundant solar light. However, the semiconductor materials available are generally limited by either poor photocatalytic efficiency in the visible light range or insufficient charge separation ability.
