School of Engineering Department of Chemical and Biological Engineering 83 Advanced Catalysts for Water Splitting and Hydrogen Production Supervisor: SHAO Minhua / CBE Student: CHAN Yik Yu / SUSEE Course: UROP1100, Spring Hydrogen is a promising and clean energy source, and it is a possible alternative to fossil fuel. However, the development of active and cheap electrocatalysts to replace Platinum remains a challenge. Among the alternative metals, ruthenium stands out because of its prominent catalytic activity, pH universal application, and cheaper cost compared to the precious metal family. Herein, ruthenium-based catalysts supported on a carbon matrix doped with different nonmetallic elements, including sulphur (S), nitrogen (N) and boron (B) were studied. Some general background will be given in this paper. Subsequently, the method of this study will be provided. Finally, the result will be discussed. Organic Molecules for Hydrogen Storage Supervisor: SHAO Minhua / CBE Student: CHAN Shun Hong / SUSE Course: UROP1100, Summer In this report, the importance of decarbonizing the energy system is addressed. Several solutions for energy carriers are mentioned. Of all of them, hydrogen was chosen to be studied. A further emphasis was put on liquid organic hydrogen carriers (LOHC in short) as it is the most efficient in terms of gravimetric density and volumetric density and has less flaws. By taking references to current successful LOHC, few key characteristics are generalized for the criteria of a good LOHC. Moreover, a structure which consists of N-heterocycles and a 5-ring structure are found to have lower dehydrogenation temperature. A few potential carriers are synthesized with the above characteristics. Further work is required to confirm its potential as a LOHC. Reusable Protein-Based Materials for Uranium Extraction from the Ocean Supervisor: SUN Fei / CBE Student: LEE Juwon / CBME Course: UROP1100, Spring The paper ‘B12-induced reassembly of split photoreceptor protein enables photoresponsive hydrogels with tunable mechanics’ utilizes the photoresponsive characteristics of newly designed proteins to address the limitations of currently existing proteins.
