C[Au]PSULE | Crystal phase engineering of Au nanoparticles for enhanced solar fuel generation

Summary
Artificial photocatalysis that converts CO2 into carbon fuels or produces clean energy such as H2 or NH3 from water and N2 using solar energy is an effective strategy to effectively reduce the carbon footprint and to develop a low carbon emission economy and sustainable energy in the future. Noble metal decorated photocatalysts have widely been investigated for improving the photocatalytic performance, however the effect of noble metal crystal phases on the photocatalytic performance is still an unexplored field. This project aims at exploiting the reduced coordination of surface metal atoms in non-standard crystal phases of metallic gold (Au) to create more effective photocatalysts. Specifically, the relationship between the Au crystal phase and the photoactivity of Au-perovskite composites will be systematically investigated by combining various advanced characterization techniques. Additionally, for achieving highly efficient Au-perovskite photocatalysts the modification of non-standard crystal phase Au by constructing crystal-phase-heterostructure and alloying with atom-thick metal shell and the optimization of charge migration pathways in the composites will be performed. Using single molecule fluorescence microscopy, the photocatalytic reaction pathways and the dynamics process over Au-perovskite photocatalysts will be elucidated.

Original description

Artificial photocatalysis that converts CO2 into carbon fuels or produces clean energy such as H2 or NH3 from water and N2 using solar energy is an effective strategy to effectively reduce the carbon footprint and to develop a low carbon emission economy and sustainable energy in the future. Noble metal decorated photocatalysts have widely been investigated for improving the photocatalytic performance, however the effect of noble metal crystal phases on the photocatalytic performance is still an unexplored field. This project aims at exploiting the reduced coordination of surface metal atoms in non-standard crystal phases of metallic gold (Au) to create more effective photocatalysts. Specifically, the relationship between the Au crystal phase and the photoactivity of Au-perovskite composites will be systematically investigated by combining various advanced characterization techniques. Additionally, for achieving highly efficient Au-perovskite photocatalysts the modification of non-standard crystal phase Au by constructing crystal-phase-heterostructure and alloying with atom-thick metal shell and the optimization of charge migration pathways in the composites will be performed. Using single molecule fluorescence microscopy, the photocatalytic reaction pathways and the dynamics process over Au-perovskite photocatalysts will be elucidated.
