Tungsten Phosphide Hydrogenation Catalyst from China
Tungsten phosphide (WP) nanoparticles are emerging as non-noble metal catalysts for hydrodeoxygenation of pyrolysis oils. This inorganic tungsten phosphide acts as a reaction initiator, offering high activity comparable to traditional sulfide catalysts. It is not a separate chemically defined element and fits under tariff item 3815.90.00.
