Photocatalysis is a process in which a catalyst facilitates a chemical reaction by absorbing and utilising light energy. The most commonly used photocatalyst is titanium dioxide (TiO2). When exposed to ultraviolet (UV) light, TiO2 can absorb the energy and generate electron-hole pairs. These reactive species can then participate in various redox reactions, leading to the degradation or transformation of organic and inorganic compounds.
At PartCat, we have engineered photocatalytic processes and materials to efficiently produce hydrogen, while simultaneously reforming organic molecules such as furfuryl alcohol into value-added products such as jet fuel precursors. The catalyst and systems we have designed have low capital and operational costs with direct solar energy inputs, creating a low-cost alternative for decentralised hydrogen production for the agriculture, mining, and chemical sectors.
