To achieve the ambitious goal of net-zero emissions by 2050, Canada has identified hydrogen as a key fuel source. Industrially, hydrogen is predominantly produced via steam reforming of natural gas which is estimated to generate 8.6 tons of carbon dioxide per ton of hydrogen produced. Therefore, affordable green production of hydrogen is extremely important for extensive commercialization of fuel cells and to reduce the carbon footprint of steam-methane reforming.In collaboration with researchers at the Leibniz Institute of Polymer Research, this project will focus on the development of inexpensive photocatalysts for hydrogen production via a solar-driven water splitting reaction. Hybrid materials composed of silicon nanoparticles and conjugated polymers will be prepared to improve the dispersibility, oxidative stability, and lifetime of the catalyst. Furthermore, by precisely engineering the hybrid material, the amount and spectral span of the solar light absorption and overall hydrogen yield will also be improved. This work will lay the foundation for the development of cost-effective catalysts for "green hydrogen" production. It will combine the polymer expertise of researchers in Germany and silicon nanostructure knowledge in Canada to form a strong network between the two countries with a common goal of reducing carbon emissions.
