    Eco-friendly dehydrogenation of dimethylamine- borane catalyzed by core-shell-looking tri-metallic RuNiPd nanoclusters loaded on white-lowering horse-chestnut seed
    (Pergamon-Elsevier Science Ltd, 2022) Ulutas, Kadir; Alshawesh, Mansour; Duman, Sibel
    Generally, white-flowering horse-chestnut seed (WFHC) found in roadsides, parks and gardens, which spills around and causes environmental pollution, is defined as waste-bio material. This study is quite remarkable as it gives WFHC a new field of usage and literally prioritizes the environment. Here, waste-bio WFHC was tested as supporter for tri-metallic RuNiPd nanoclusters in the eco-friendly dehydrogenation of dimethylamine-borane (DMAB). Core-shell-looking tri-metallic RuNiPd@WFHC, with 264.09 +/- 45.55 nm particle size, were in-situ synthesized throughout dehydrogenation of DMAB at 35.0 +/- 0.1 degrees C. The WFHC and tri-metallic Ru2.00Ni1.86Pd1.00@WFHC NCs were characterized by advanced analysis and their surface morphologies were studied in detail using adsorption models. The N2 adsorption-desorption and logarithmic-Freundlich plots indicated that surface morphologies have heterogeneous multi-layer and typical Type-III isotherm with meso-porous surfaces. Also, detailed kinetic studies were actualized on the dehydrogenation of DMAB catalyzed by tri-metallic Ru2.00Ni1.86Pd1.00@WFHC NCs with 158 h-1 TOF value.(c) 2022 Hydrogen Energy Publications LLC.
