Structure-sensitivity of formic acid dehydrogenation reaction over additive-free Pd NPs supported on activated carbon

In this study the size-activity dependence of palladium based catalysts in formic acid dehydrogenation reaction was investigated and evaluated. A wide range of particle sizes was considered and the catalyst series were prepared upon variation of some synthetic parameters, precursor and solvent natur...
