Carboxylic acid hydrodeoxygenation (HDO) over supported noble metal catalysts was carried out in order identify the main challenges associated with supported monometallic catalysts and identifying solutions that may increase the practicality of these high activity metals. Using propionic acid as a probe molecule, it was found that supported platinum (Pt) and ruthenium (Ru) catalysts have two main issues: selectivity and stability. Both metals are quite unselective towards HDO products, multiple chemistries occur over the catalysts that lead to a myriad of undesired products. Decarbonylation (DCN) is the most selective pathway over Pt catalysts, while both DCN and methanation chemistries are …
