Abstract

The invention discloses a gold nano flower catalyst taking biomass activated carbon as a carrier as well as a preparation method and application thereof. According to the catalyst, waste shaddock peels are made into a porous activated carbon carrier, and gold nano flowers are taken as a catalytic active component. Based on the mass of the carrier, the mass percentage of the active component is 0.1-0.3%. The preparation method comprises the following steps: carrying out drying, pre-oxidation, carbonization, crushing, activation and other processes on waste shaddock peels to prepare a porous activated carbon carrier, reducing an active component precursor solution into a gold nano flower colloidal solution by using ascorbic acid, dipping the porous activated carbon carrier into the active component colloidal solution, and drying to obtain the reforming hydrogen production catalyst. Waste shaddock peels are converted into resources. The reforming hydrogen production catalyst has high H2 selectivity and a low noble metal content, the preparation technology is simple, the problem of carbon deposition of a reforming hydrogen production catalyst is solved, and the market application prospect is wide.

Description

technical field [0001] The invention relates to a catalyst of gold nanoflowers with biomass activated carbon as a carrier, a preparation method and application thereof, and belongs to the technical fields of resource utilization of waste products and new energy. Background technique [0002] As the global energy shortage becomes increasingly severe, the development and utilization of clean energy is imminent. Hydrogen, as a clean, efficient and renewable energy, is attracting extensive attention from researchers around the world. Commercial hydrogen production processes mainly fall into three categories: water electrolysis, coal gasification, and catalytic reforming, among which catalytic reforming is one of the hydrogen production processes with the greatest development potential. At present, the hydrogen sources of the catalytic reforming hydrogen production process are mainly methane, ethanol, methanol, etc. These hydrogen sources themselves have certain energy utilizati...
