This PhD project aims at the development of advanced hybrid catalytic materials based on MXenes and related 2D systems for photoelectrochemical energy conversion processes. The research will focus on solar-driven reactions that provide alternative technological routes to conventional fossil-based processes, such as photoelectrochemical (PEC) water splitting for H₂ production and PEC CO2 reduction. The project will concentrate on MXene-based hybrid materials, in which MXenes serve as conductive, catalytically active components coupled with suitable visible-light-responsive photoactive materials. The primary focus will be on semiconducting metal oxides and layered double hydroxides (hydrotalcite-like materials), whose optical and electronic properties can be tuned to absorb in the visible region and to facilitate efficient charge separation. These photoactive phases will be interfaced with MXenes to construct well-defined heterostructures. Particular emphasis will be placed on interface engineering to enhance charge separation, suppress recombination, and ensure long-term stability under operating conditions relevant to solar fuel production. The project lies at the intersection of materials science, catalysis, and electrochemistry and will provide the candidate with broad expertise in catalyst design for sustainable energy technologies within an international research environment.
