Abstract: This investigation was synthesis of the four types (A, B, C, D) of polypyrrole /Nb2O5/graphene nanocomposite at different percentage as photo catalyst. The synthesis was by hydrothermal method and polymerization (0.05, 0.1, 0.15, 0.2 g) Nb2O5/graphene with 0.6 M pyrrole and drying at temperature 60°C for 24 h. The synthesis nanoparticle by using hydrothermal and calcination at temperatures 700°C for 2 h. Synthesis powders were characterized by AFM, Raman, PET, PJH, XRD, FT-IR, UV-visible and band gap. The photocatalytic activity and electrical properties were studied estimated under high pressure mercury lamp osram (125 wt.) for degradation acridine orange solution at the wave length of 477 nm. It is found the optimum mass catalyst D at 0.2 g and optimum concentration of 20 ppm, the optimum pH 7, temperature 25°C. The X-Ray studies showed the crystal size of composite in the range 4-54 nm. The electrical properties shows in the nanoparticle and poly pyrrole is found weak conductivity and catalyst (A, B, C, D) is higher conductivity.
