Recently, Li Zhao, a postgraduate of School of Materials Science and Chemistry published the research achievement titled “Localized surface plasmon resonance promotes metal-organic framework-based photocatalytic hydrogen evolution”in Advanced Functional Materials. Li Zhao was the first author; Professor Lian Zichao was the sole corrsponding author.
Due to the nonrenewable characteristics of fossil fuels, their combustion is often accompanied by the production of harmful gases such as nitrogen oxides, sulfur oxides, and carbon dioxide, and thus it is urgent to find clean, renewable, and efficient energy materials to replace fossil fuels. Photocatalytic water splitting to produce hydrogen has become an important way to solve the energy crisis and environmental pollution problems due to its clean and environmentally-friendly advantages.
They successfully synthesized a ternary MOF-based composite Au@NH2-UiO-66/CdS with strong LSPR effect. The Au@NH2-UiO-66/CdS exhibited high performance in the photocatalytic HER through adjusting the size of Au NPs and the loading of CdS under visible light irradiation. The time-resolved transient absorption measurements revealed the photo-induced carrier dynamics of the Au@NH2-UiO-66/CdS, which exhibited long-lived charge separation for enhanced photocatalytic activity in HER. In addition, the sizes of Au NPs and the LSPR effect are key factors in the photocatalytic HER process. This study plays a guiding role in the construction of efficient MOF-based multi-composite photocatalysts with strong LSPR effects for efficient photocatalytic This work was supported by the National Natural Science Foundation of China and the Natural Science Foundation of Shanghai.
