Abstract

The invention discloses a reduced graphene oxide / porphyrin / platinum nanocomposite material and its preparation and application, and belongs to the technical field of photocatalysis. The present invention uses reduced graphene oxide with good electrical conductivity as the anchoring group molecule, and uses rod-shaped 5,10,15,20-tetrakis (4-carboxyphenyl) porphyrin with the best photocatalytic performance among porphyrins. The reduced graphene oxide film is modified, and finally platinum nanoparticles, which are the best catalytic hydrogen evolution materials, are loaded on the modified reduced graphene oxide film through photoreduction method. The prepared ITO‑RGO‑TCPP NR‑PtNPs nanocomposite has It has good photocatalytic performance and can be used as a catalyst in the photocatalytic hydrogen production process. The entire method has a short process flow, simple experimental conditions, low cost, and does not cause pollution to the environment, meeting the requirements of clean production.

Description

technical field

[0001] The invention relates to the technical field of photocatalysis, in particular to a reduced graphene oxide / porphyrin / platinum nanocomposite material and its preparation and application of the nanocomposite material as a photocatalyst. Background technique

[0002] With the rapid development of social economy, the energy and environmental crisis has become a global problem. Therefore, on the basis of rational use of fossil energy, the development of clean and renewable energy to replace fossil fuels is an extremely urgent problem facing the world today. Solar energy is undoubtedly a very good renewable energy source. However, only natural photosynthesis cannot meet the increasing energy demand of human beings. Therefore, converting light energy into chemical energy by constructing non-natural photosynthetic materials is the current solution for people to resolve energy. One of the best strategies for a crisis. However, the existing semiconductor photoca...
