Dehydrogenation of formic acid using molecular Rh and Ir catalysts immobilized on bipyridine-based covalent triazine frameworks

Abstract

In this study, catalytic dehydrogenation of formic acid into H₂/CO₂ using half-sandwich Rh(III)/Ir(III) catalysts immobilized on variable dimensions of bipyridine-based covalent triazine frameworks (bpy-CTFs) has been described for the first time with a highest initial turnover frequency of 7930 h⁻¹. A systematic study on the influence of the central metal cation (Rh vs. Ir), CTF architectures and amount of metal loadings on the CTF is presented.
