Abstract

In real life, nanotechnology has a wide range of uses, nanoparticles have large specific surface area, high activity, special foreign matter, small characteristics. Nanoparticles as catalysts is one aspect of the performance of nanomaterials. In this paper, taking Ag and Cu alloys as examples, the mechanism of nanocatalyzer is introduced, which significantly improves the catalytic activity of Cu, and the experimental application of converting mixed CO2/CO/H2 materials into methanol (CO2+3H2 →CH3OH+H2O) in industry is analyzed. In order to further optimize the activity of the catalyst, carbon nanotubes were introduced as the catalyst carrier, and single metal or alloy nanoparticles were loaded on the surface of the catalyst. Compared with the unsupported catalyst with the same alloy ratio, the catalytic activity of the prepared carbon nanotubes supported alloy nanocatalyst was significantly improved. Meanwhile, nanocatalysts have important applications in energy saving and environment protecting.
