Reactivity of borohydride incorporated in coordination polymers toward carbon dioxide

Abstract

Borohydride (BH₄⁻)-containing coordination polymers converted CO₂ into HCO₂⁻ or [BH₃(OCHO)]⁻, whose reaction routes were affected by the electronegativity of metal ions and the coordination mode of BH₄⁻. The reactions were investigated using thermal gravimetric analysis under CO₂ gas flow, infrared spectroscopy, and NMR experiments.
