Polyaniline-Supported Tungsten-Catalyzed Green and Selective Oxidation of Alcohols

Polyaniline (PANI)-supported tungsten could be easily fabricated by immersing PANI into the tungsten salt solution. It was a high efficient catalyst for alcohol oxidation reaction to produce carbonyls. Notably, the selectivities of the oxidation of primary alcohols were good, affording aldehydes as the specific products. The high catalytic activity might attribute to the coordination of nitrogen in PANI with tungsten in the materials, while the unique structure afforded the catalyst high selectivity for primary alcohol oxidation.
