Eco-friendly dehydrogenation of dimethylamine-borane catalyzed by core-shell-looking tri-metallic RuNiPd nanoclusters loaded on white-flowering horse-chestnut seed

Abstract

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 °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 mesoporous 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.
