TI  - Copper Oxide-Antimony Oxide Entrapped Alginate Hydrogel as Efficient Catalyst for 
      Selective Reduction of 2-Nitrophenol.

AB  - Copper oxide-antimony oxide (Cu(2)O-Sb(2)O(3)) was prepared and entrapped inside 
      Na-alginate hydrogel (Alg@Cu(2)O-Sb(2)O(3)). The developed Alg@Cu(2)O-Sb(2)O(3) 
      was used as catalytic reactor for the reduction of 4-nitrophenol (4-NP), 
      2-nitrophenol (2-NP), 2,6-dinitrophenol (2,6-DNP), methyl orange (MO), congo red 
      (CR), acridine orange (AO), methylene blue (MB) and potassium ferricyanide 
      (K(3)[Fe(CN)(6)]). Alg@Cu(2)O-Sb(2)O(3) was found to be selective and more 
      efficient for the reduction of 2-NP among all the pollutants. Therefore, 2-NP was 
      selected for a detailed study to optimize various parameters, e.g., the catalyst 
      amount, reducing agent concentration, 2-NP concentration and recyclability. 
      Alg@Cu(2)O-Sb(2)O(3) was found to be very stable and easily recyclable for the 
      reduction of 2-NP. The Alg@Cu(2)O-Sb(2)O(3) nanocatalyst reduced 2-NP in 1.0 min, 
      having a rate constant of 3.8187 min(-1).
