The selection of a metal precursor depends on several factors:
1. Solubility: The precursor should be soluble in the medium used for catalyst preparation to ensure uniform distribution. 2. Stability: The precursor must be stable under the synthesis conditions to prevent premature decomposition. 3. Reactivity: The precursor should decompose or react to form the active metal species without leaving unwanted residues. 4. Cost and Availability: Economic considerations and the availability of the precursor also play a significant role.
