Method for producing hydrogen by photocatalysis of nitrogen-containing heterocyclic compound

Abstract

The invention discloses a method for producing hydrogen by photocatalysis of a nitrogen-containing heterocyclic compound, which realizes the hydrogen production effect of the nitrogen-containing heterocyclic compound under the condition of visible light by adding a porphyrin-based catalyst into a nitrogen-containing heterocyclic compound solution. According to the invention, the porphyrin-based catalyst is applied to a process for producing hydrogen by photocatalysis of the nitrogen-containing heterocyclic compound for the first time; the method has the advantages of mild reaction conditions,simple operation, excellent hydrogen production performance, effective avoiding of the use of precious metals, realization of recycling, provision of a brand new idea for the efficient dehydrogenationtechnology of nitrogen-containing heterocyclic compounds, and wide application in the field of energy sources.

Description

technical field [0001] The invention belongs to the technical field of photocatalytic hydrogen production, and relates to a method for photocatalytic hydrogen production of nitrogen-containing heterocyclic compounds. Background technique [0002] The dehydrogenation reaction of nitrogen heterocyclic compounds usually needs to be carried out under the conditions of high temperature (>100 ℃) and the participation of noble metal catalysts (such as, R.Yamaguchi, C.Ikeda, Y.Takahashi, K.I.Fujita, J.Am.Chem .Soc.2009,131,8410-8412; etc.), even under photocatalytic conditions, also need the participation of noble metal catalysts (K.H.He, F.F.Tan, C.Z.Zhou, G.J.Zhou, X.L.Yang, Y.Li, Angew. Chem.Int.Ed.2017,56,3080-3084.); In addition, the photocatalysts used in the existing nitrogen heterocyclic compound dehydrogenation process are usually metal organic compounds, which are difficult to recycle and reuse, which is not conducive to reducing process costs and energy consumption. ...
