Hydrogenation and cross-coupling reactions are of great importance for industrial applications noble metal based catalysts filling the void since last few decades. However, high cost metals poor recycling performance provides an opportunity chemists to look alternate options. Herein, we present use Lanthanum hydroxide as support loading ultra-low amount Pd hydrogenation reactions. having controlled morphologies comprises exposed crystallographic facets which interact with small sized NPs shows versatile effective catalytic performance. The reduction 4-NP over Pd/La(OH)3 was achieved within very short time (45s) a rate constant 60 × 10-3 s-1. styrene also accomplished 1 hour much TOF value (3260 h-1). Moreover, Suzuki cross-couplings iodobenzene phenyl boronic acid into biphenyl completed 35 min 389 h-1. strong interfacial electronic communication regulates electron density sites lowers energy adsorption reactant subsequently conversion products. abundant hydroxyl groups on surface La(OH)3, large area, mono-dispersity ultra-small size favors efficient reactants.
