Novel Inorganic-Organic Combined Complex Metal Hydrides for Energy-Related Applications

With increasing concerns on global climate change, many efforts have been made to tackle this challenge. Development of clean energy such as hydrogen and electricity generated by renewable energy sources will simultaneously reduce the dependence on fossil fuel and emissions of greenhouse gases and pollutants. While for the existing anthropogenic carbon dioxide from combustion of fossil fuels, carbon capture and storage are widely acknowledged as a necessary carbon abatement strategy. Complex hydrides have been intensively studied as promising solid-state hydrogen-storage materials and electrolyte materials for battery applications. They recently have also attracted attention for their potential usage for CO₂ capture and conversion. In this talk, I am going to present our work on development of novel complex metal hydrides, particularly inorganic-organic combined complex hydride systems, with interesting relevant versatile properties for diverse applications such as hydrogen storage, ionic conduction, and CO₂ capture. The talk will focus on the structural studies of these materials. The rich information obtained from the structural analysis and its implications for hydrogen storage, ionic conduction, and CO₂ capture of the related hydrides will also be discussed.
