Combination of nanoparticles with single-metal sites synergistically boosts co-catalyzed formic acid dehydrogenation.

ABSTRACT: The development of hydrogen technologies is at the heart of a green economy. As prerequisite for implementation of hydrogen storage, active and stable catalysts for (de)hydrogenation reactions are needed. So far, the use of precious metals associated with expensive costs dominates in this area. Herein, we present a new class of lower-cost Co-based catalysts (Co-SAs/NPs@NC) in which highly distributed single-metal sites are synergistically combined with small defined nanoparticles allowing efficient formic acid dehydrogenation. The optimal material with atomically dispersed CoN₂C₂ units and encapsulated 7-8 nm nanoparticles achieves an excellent gas yield of 1403.8 mL·g^-1·h^-1 using propylene carbonate as solvent, with no activity loss after 5 cycl
