Abstract

In this work, a Suzuki cross-coupling procedure towards highly porous BINAP-based polymeric Ru-catalyst materials with tunable specific surface areas (SSAs) were synthesized and their stability towards reducing conditions was investigated. After the removal of Pd impurities by an oxidative treatment with H₂O₂/HCl, P=O reduction and metal loading, the resulting catalysts were employed for the base-free ruthenium-catalyzed decomposition of aqueous formic acid to CO₂ and H₂ with TOFs of up to 134 000 h⁻¹ and TONs up to 920 000.
