Wired: With silicon as a photocathode and [Ni(bpy)2] as a catalyst, visible light-powered CO2 photofixation is made possible (see picture). Owing to their multifaceted surfaces, silicon nanowires show a significantly better performance compared to planar Si. The shape of a nanowire is indeed an appealing materials choice for high-efficiency, low-cost solar energy conversion applications.
