Wired: With silicon as a photocathode and [Ni(bpy) 2 ] as a catalyst, visible light‐powered CO 2 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.
