  • Applications

    Nickel formate (CAS 3349-06-2) is primarily used as a precursor to nickel-containing catalysts and nickel nanoparticles, which are employed in hydrogenation, reforming, and related industrial processes. It also serves as a metal-organic precursor for depositing nickel in thin films and coatings by methods such as chemical vapor deposition (CVD) or atomic layer deposition (ALD), and as a Ni source for conductive inks and coatings after appropriate reduction. In organometallic synthesis it functions as a nickel source for complex formation and as a thermally decomposable precursor to Ni or NiO particles for catalytic materials. It may also act as an intermediate in ceramic or polymer systems where nickel serves as a dopant or catalytic additive. Use is process-dependent and subject to local regulations and formulation limits.
