Abstract
Catalysis is very important process in industry and laboratory practice, especially from the point of green chemistry principles. However, eco-friendly character of heterogeneous catalysts, containing transition metal components has not been evaluated, yet. Therefore, we perform a comprehensive assessment of 18 heterogeneous metal catalysts (Pd, Pt, V, Co, Ni, Mo, Ru, Mn, Au, Cu, Cd, Zr, Fe, Rh, Ir, Sn, Zn, Ag) using multicriteria decision analysis approach. The ranking of alternatives according to relevant criteria like toxicity of pure metals and metal salts towards fish and Daphnia magna, algae/plants, metal toxicity towards rats via ingestion, carcinogenicity, the endangerment degree of metals, boiling point and energy for atom detachment, estimated as metal-metal bond strength in diatomic transition metal units, classification of elemental impurities according to International Conference on Harmonization (ICH)and their degree of importance is presented. Life cycle assessment (LCA) related parameters of metals have been also included. The assessment showed ruthenium, iron and molybdenum as the most favourable alternatives, in contrary to nickel, cobalt and rhodium. Results of environmental evaluation strictly depend on chosen scenario of assessment, in terms of toxicity, endangered elements or LCA. Sensitivity analyses towards variations in input data and applied weights, prove that results are reliable. Multicriteria decision analysis can be successfully applied in metal catalysts evaluation for particular case studies of different reactions.
