Latest Patents

Feng’s listed patent, “Binary Ferrihydrite Catalysts,” describes methods for preparing a catalyst precursor. One method dissolves an iron salt and an oxoanion-forming agent salt in water at a specified oxoanion-to-iron ratio, then raises the solution’s pH to 10 with a strong base. The resulting precipitate is collected with a binary ferrihydrite structure.

An alternative method forms ferrihydrite precipitate by bringing an iron-salt solution to approximately pH 10. The precipitate is filtered, washed with distilled water, and mixed with a hydroxy carboxylic acid solution. After agitation, the binary ferrihydrite precipitate is filtered and recovered.
