Silicon Nanowires Show Improved Performance as Photocathode for Catalyzed Carbon Dioxide Photofixation

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 appe...

Description
Summary: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.
