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.
目前,正丁烷脱氢异构催化剂可以分为两,金属双功能催化剂和金属氮化、碳化和碳氧化催化剂。
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.
