The present invention is a hydrogenation catalyst comprising a transition metal complex coordinated to a covalent organic framework (COF), characterized in that two or more identical anion ligands are introduced into the coordination sphere of the complex, Wherein the transition metal is selected from the group consisting of Ir, Pt, Pd, Ru, Rh, Ni, Fe, Cu, V, Co, Cr, Au, Re, W, Zr, and is at least one selected from the group consisting of Mo, an anion ligand-introduced to the exhaust top are carboxylates, oxalates, carbonates, acetyl acetonates oxygen anion ligand (oxyanionic ligand) selected from or Cl -, Which is an anionic ligand selected from Br - , I - , SO 4 2- , CF 3 SO 3 - , NO 3 - , and PF 6 - , and a process for hydrogenating carbon dioxide using the hydrogenation catalyst. And is highly useful industrially since it is excellent in recyclability in a continuous process. |
