Photoelectrocatalytic H2 Production

Abstract

The production of sustainable H2 through photoelectrocatalytic (PEC) water splitting is a continually developing technology that is anticipated to play a major role in the future hydrogen infrastructure. Although notable research efforts have been devoted to the field, industrial-scale adoption of PEC technologies has been hindered by low efficiencies, high device costs, and poor stability. Various strategies and approaches have emerged in recent years to tackle these concerns. The following chapter aims to highlight these strategies and discuss future outlooks in the field of PEC water splitting. Initially, the parameters affecting PEC H2 production are described, followed by recent innovations in photoelectrode semiconductor technologies. Later, the most noteworthy PEC reactor configurations are discussed before finalizing with design considerations for new PEC prototypes.
