Abstract:
Magnetic hydrogel derived from wheat straw cellulose (WSC) and feather protein (FP) was successfully derived from [Bmim]Cl ionic liquids for copper nanoparticles carrier to prepare magnetic hydrogel-Cu (m-WSC/FP-Cu). Morphology, structure and component of m-WSC/FP-Cu were characterized by different techniques (SEM, TEM, XRD, FTIR, VSM, etc.). The activity of m-WSC/FP-Cu were evaluated by employing them as catalysts for the reduction of 2-nitrobenzoic acid (2-NA) to a useful industrial intermediates, 2-aminobenzoic acid (2-ABA). Effect of experimental conditions, including m-WSC/FP-Cu dosage, 2-NA initial concentration, NaBH4 dosage and temperature, were investigated. The m-WSC/FP-Cu exhibited maximum catalytic activity under conditions of 1.00 g m-WSC/FP-Cu, 100 mg/L 2-NA and 0.3 g NaBH4. Besides, higher activity of m-WSC/FP-Cu was obtained at higher temperature. The activity of m-WSC/FP-Cu maintained 99.02% over 5 cycles utilization and 90.60% after 30 days storage, which exhibited excellent recyclability and stability. It is expected that the m-WSC/FP-Cu have the potential for treating organic wastewater cooperated with a catalyst regeneration device.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
