Synthesis of a palladium nanoparticle catalyst boosts hydrogen production in formic acid dehydrogenation, highlighting the role of boron nitride. This work suggests advances in catalyst design.
Palladium nanoparticles anchored on aminosilane-functionalized porous boron nitride (Pd/p-BN-APTES) were synthesized by impregnation-reduction. The functionalized support enabled uniform dispersion of ~2.2 nm Pd nanoparticles. During additive-free, room-temperature formic acid dehydrogenation, this catalyst exhibited exceptional activity: 116 mL of gas evolved within 11 min at 298 K, yielding an initial turnover frequency (TOF) of 532.1 h −1 . Gas chromatography confirmed 100% H 2 selectivity with undetectable CO. Control experiments using pristine p-BN, APTES alone, and unmodified Pd/p-BN showed markedly inferior performance, highlighting the synergistic contribution of small Pd particle size and abundant anchoring sites on the functionalized support. This work establishes a versatile strategy for designing efficient boron nitride-based hydrogen production catalysts.
