Abstract

Abstract: The Co3O4@Si nanowires configuration was successfully fabricated by employing the electroless metal deposition (EMD) technology and the following annealing in air. The nanostructure exhibits a uniform Co3O4 nanoparticles grafting on the solution-etched aligned Si nanowires. What is more important, the cost-effective and uncomplicated fabrication strategy as well as the obtained unique architecture will lead to perfect performance in many applications. When functioned as anode electrodes in lithium-ions battery, the Co3O4@Si nanowires configuration displays an excellent Lithium-ion battery performance with larger reversible capacity, more comforting cyclic performance and better rate capability compared with the commercial Co3O4 powders.

Abstract

Abstract: Bi2SiO5 modified Si nanowire array films were fabricated as photo-catalysts via dip-coating Bi(NO3)3 on silver-assisted electroless wet chemical etching Si nanowires and subsequently annealing. The structures and morphologies of as-prepared samples are characterized by X-ray diffraction, Fourier transform infrared spectrum, scanning electron microscopy and transmission electron microscopy. The results of photocatalytic experiments indicated that the Bi2SiO5 modified Si nanowire arrays benefit the improvement for efficient electron–hole separation and photo-catalytic stability, thereby possessing superior photo-degradation performance. These hybrid nanowire arrays will be promising materials for photo-catalysts and degradation agents. [Copyright &y& Elsevier]
