PHOTOGRAPH: where PHOTOelectrochemical hydrogen production meets GRAPHene-based interfaces

PHOTOGRAPH is subproject (Ref. PID2019104272RB-C51) of a coordinated national project entitled NEXT-ENER, associated at the 2019 national R&D program "Proyectos de I+D+i - Retos" and led by the Group of Carbon Nanostructures and Nanotechnology (G-CNN) at the Instituto de Carboquimica (ICB-CSIC). Within the overall frame of the coordinated project, devoted to the integration of new energy conversion and storage technologies and, being developed by five Spanish research groups, PHOTOGRAPH focuses on the photoelectrochemical hydrogen production using optimized graphene-based interfaces. The main motivation of PHOTOGRAPH is to improve the photoelectrochemical device performance while reducing costs and the ecological footprint, directly tackling several problems that humankind is facing nowadays. In this communication, a journey throughout past, present and future perspectives of PHOTOGRAPH is presented, especially emphasizing ongoing activities.
