Novel synthesis of dual-suspended architectures between Si-pillars for enhanced photocatalytic performance

Abstract

A facile approach is developed to synthesize a dual-suspended architecture, in which 3D carbon nanotube (CNT) networks are first bridged between Si pillars through a catalyzed method and suspended oxide architectures are subsequently synthesized on CNT networks through pulse electrodeposition. These dual-suspended structures show excellent photocatalytic activity toward methylene blue (MB) photo-decomposition under visible light illumination.
