Photoelectrochemical Application of Nanomaterials

Tremendous progress has been made in the aspect of material design, especially in nanomaterials fabrication over the past decades. And as such, the rapid development of nanomaterials through nanotechnology has opened up new avenues for their use in photoelectrochemical applications. Their unique characteristics at nano dimensions compared to their bulk counterparts make them very much attractive. Largely, optical properties and functionalities in emerging technologies, flexibility and semiconducting properties to mention a few make the use of nanomaterials indispensable for photoelectrochemical applications. Owing to this effect, the present chapter deals with the photoelectrochemical (PEC) application of nanomaterials in specific areas such as photoelectrochemical biosensing, hydrogen production via solar water splitting and photovoltaic devices. The chapter also addresses the progress in the utilization of the nanomaterials and illustrates the designs for their integration in biosensors, highly efficient and stable photoelectrode in PEC water splitting for hydrogen production and outstanding smart solar energy harvesting devices for third-generation photovoltaics.
