We are one of the leading natural ingredient company in China,our products are widely used in health foods,beverages,pharmaceuticals,personal care and beauty products. We also develops, manufactures, and distributes specialty niche chemicals, including norbornene, phosphines, fluorene derivative,metal catalysts organic synthesis,drug and chemical product research for multi-industrial and pharmaceutical applications. We have researched and developed dozens of noble metal catalysts, mainly including: platinum/carbon, palladium/carbon, ruthenium/carbon, rhodium/carbon, silver/carbon, iridium/carbon, oxide. ceramic material carrying noble metal catalyst, organic material carrying noble metal catalyst, inorganic salts carrying noble metal catalyst, noble metal homogencous catalysts and gas-purifying catalysts(oxygen, nitrogen, argon, hydrogen, tail gas, methanation etc.), catalytic combustion catalysts( remove organic substance, waste gas etc.). Besides, we can produce more than 50 kinds of noble metal compounds and ten kinds of noble metal super fine and nanometer powder. Products are widely used in the fields including chemistry industry(including medical), nuclear industry, energy industry, material industry, electronic industry, war industry and environmental protection etc.. Some products are exported to Europe and Southeast Asia etc.. Our company has the abilities to do the following business for our clients: development of special catalyst, catalyst design, consultation of organic synthesis, recovery and reuse of waste catalysts.
