Many decades of research in heterogeneous catalysis have yielded a wealth of knowledge on how to prepare metal nanoparticles in mesoporous carbon and oxide supports . However, it is seldomly realised that this knowledge might be extremely useful also for the development of new materials for energy storage and conversion, such as in batteries, supercapacitors, fuel cells, gas storage materials and solar fuels materials. Vice versa the search for new energy storage and conversion materials might inspire unorthodox approaches to identify new, promising catalysts based on low-cost and earth abundant elements.
In my presentation I will highlight two examples. In the first case study I will discuss how industrial catalysts preparation techniques have led to the preparation of Cu2O photocatalysts for the production of renewable hydrogen. In the second case I will show that supported light metal hydrides, NaAlH4 and LiNH2, originally studied for reversible hydrogen storage, show intriguing catalytic properties[3,4].
