The invention discloses a carbon nano bowl-shaped catalyst, a preparation method and application of the carbon nano bowl-shaped catalyst in paired electric synthesis of cinnamyl
aldehyde and 3-phenylpropanol from
cinnamyl alcohol, the catalyst comprises a carbon nano bowl-loaded
nickel catalyst and a carbon nano bowl-loaded
palladium catalyst, and a flowing diaphragm type
electrolytic cell is adopted for reaction, taking a carbon nano bowl loaded
nickel catalyst as an
anode chamber
electrode, and dissolving
cinnamyl alcohol in an alkaline solution to serve as anolyte; the method comprises the following steps: by taking
cinnamyl alcohol as a
raw material, taking a carbon nano bowl loaded
palladium catalyst as a
cathode chamber
electrode, dissolving cinnamyl
alcohol in an acid solution as a
cathode solution, carrying out paired
electrosynthesis reaction at the temperature of 15-60 DEG C, the
current density of 50-150mA / cm < 2 > and the
cell voltage of 1-8V for 0.3-3.0 hours, and after the reaction is finished, carrying out post-treatment to obtain cinnamyl
aldehyde and 3-phenylpropanol. The paired
electrosynthesis process is mild in condition, high in
raw material conversion rate and good in selectivity, compared with a commonly-adopted
noble metal catalyst and a single-groove synthesis technology, the used carbon nano bowl-shaped catalyst is low in cost, and the paired
electrosynthesis technology is high in energy
utilization rate.
