Au–Pd nanoparticles were synthesized on the surface of silicon nanowires and used in the degradation of the p-nitroaniline, which exhibited the mutual promotional effect compared with Au/Si and Pd/Si catalysts. This synergistic effect factor was calculated as 2.35. The Au–Pd/Si catalysts might be recycled and used again. The catalytic rate of the catalysts only decreased by 20% after recycling for five times.

    Silicon nanowires with axially varying n- and p-doping were grown by the vapor-liquid-solid approach using gold as the catalyst. The nanowire sidewalls exhibit periodic nanofaceting, which is found to be dopant-dependent. It is shown that the nanofaceting occurs during the enhanced sidewall...
