Patricia A. Davis is a notable inventor based in Newport News, VA (US). She has made significant contributions to the field of catalysis, particularly in the development of processes involving noble metals.

Latest Patents

Davis holds a patent for a process for making a noble metal on a tin oxide catalyst. This innovative method involves the use of reagent grade tin metal or compound, chloride-free, and high-surface-area silica spheres. The process begins with placing these materials in deionized water, followed by deaeration through boiling and the addition of an oxidizing agent, such as nitric acid. The nitric acid oxidizes the tin to metastannic acid, which coats the silica spheres. Upon drying and calcining, the metastannic acid transforms into tin oxide. The tin oxide-coated silica spheres are then boiled in water, and a chloride-free precious metal compound in aqueous solution is added. This compound is reduced to a precious metal using a suitable reducing agent, such as formic acid. Notably, beneficial results have been achieved using the precious metal compound tetraammine platinum(II) hydroxide.
