Synthesis and study of the pseudocapacitive behavior of heterojunctional NiTiO3-based chitosan nanocomposite

摘要: Abstract A microwave-assisted synthesis of a NiTiO3-based chitosan (NT/CS) nanocomposite with acceptable pseudocapacitive performance is reported. The requisite NiTiO3 nanoparticles were prepared by simple, ultrafast, one-pot combustion technique activated microwave heating at power 900 W for 20 min. This reaction was performed in the solid state, using urea and ammonium nitrate as fuel oxidant, home-made set-up encircled CuO jacket to capture radiation. Detailed study structural morphological characteristics resulting products revealed successful fabrication NiTiO3/CS particles pure phases average particle sizes about 30 39 nm, respectively. behavior evaluated through series electrochemical tests, including cyclic voltammetry (CV) impedance spectroscopy (EIS) different scan rates potentials. results indicated an increased specific capacitance (197 F g−1) NT/CS film compared that pristine (76 F g−1) potential rate 10 mV s−1. Further CV examination after 2000 cycles capacity retention around 86%, indicating good recyclability long cycle life. band-gap energy product its relationship also discussed detail. obtained show be highly promising electrode material applications.
