Catalytic converters in vehicles require expensive precious metals such as platinum, rhodium and palladium to reduce the toxicity of exhausts. To lower the usage of the precious metals, I am developing a novel nanomaterials system that only consumes 10% of the precious metals of conventional automotive catalysts. Another advantage of the system is that it is even more stable and has the potential to be more catalytically active than the conventional converters. Apart from the project above, my PhD work involves extensive topics: biochar for wastewater treatment, photocatalysts for hydrogen production and thin films for smart glass applications.
