Abstract
- Nickel-cobalt (Ni-Co) metal ion modified manganese oxide is prepared by a surfactant-assisted precipitation method through the in situ-doping into manganese oxide matrix. The prepared manganese oxide showed good porous property and improved surface area values and was further impregnated via reducing graphene oxide by an ultrasonication-assisted deposition method. The nanocomposite was decorated by adding commercial MoS2 nanoparticles to fabricate the binary nanocomposite. The thermal stability of the as-prepared sample was stable up to 450−500 °C in an air atmosphere and a negative zeta potential was obtained for most of the prepared nanocomposite sample. MoS2nanoparticle appeared as spherical nanoparticle at a smaller particle size formation (10−20 nm) on porous Ni-Co-MnOx surfaces, and nanoparticle deposition and graphene nanosheets act as a structure-directing agent toward layered nanotubes morphology formation for mesoporous manganese oxide. The as-prepared binary nanocomposite was further tested for toxic catalytic nitrophenol degradation under visible light exposure condition.
