1.The catalysts on studying can divide into two kinds: the transition metal bifunctional catalysts and the nitride, carbide and oxycarbide catalysts of transition metals.
2.The reason for the fail of carbon nitride synthesis was analysed and relevant graphitoid carbon nitride and unformed carbon nitrides were introduced in the article.
4.Copper ions are frequently poisonous to biological systems.So Dr Bertozzi decided to work on a way to make azides and alkynes react without their involvement.
