(Invited) Boosted Photoelectrochemical Water Splitting Performance by Plasmonic Assisted Ternary Heterostructures

Traditional semiconducting metal oxide-based photoelectrodes have been extensively explored for energy and environmental applications. However, their performance is hindered by poor light absorption, high charge recombination rates, and low surface kinetics. Some of the recent results will be presented to discuss the rational design of ternary materials systems, which incorporating of metal-organic framework and plasmonic structures into semiconducting metal oxides, as one of the most promising strategies to achieve performances beyond those of bare MOF and/or conventional semiconductors. The application examples of this new generation of composite photoelectrodes in water splitting, CO 2 reduction and pollution degradation will be discussed, together with the challenges and prospects.
