报告摘要:

Hydrogen generation from photocatalytic and photoelectrochemical water splitting under visible light has been considered as an effective way to make solar energy storable and transportable. As oxygen is the only by-product from splitting water, this reaction has great potential to simultaneously address the energy shortage and environmental issues by replacing fossil fuel. A great number of photoactive semiconductors (be it oxide, sulphide or etc) has attracted extensive attention due to its low-cost, mostly non-toxic, usually high stability, and with considerable theoretical photocurrent density for H2 generation. These characteristics meet favourably the requirements for water splitting. In contrast, the challenges in extending their capability in this application lie on several aspects, such as the extension of the solar spectrum absorption, the charges transportation, and the photo-stability of the materials. Introduction of nanosctructures or secondary components into the parental semiconductor is a potential way in tackling the above mentioned issues. Therefore, the main driving force for our research in SEE CityU is to improve (if not overcome) the above shortfalls by using several different electrochemical and chemical synthetic approaches.

报告人简介:

Prof. Ng received his Ph.D. from Osaka University in 2009. After a brief research visit to Radiation Laboratory at University of Notre Dame (Prof. Prashant Kamat’s group), he joined the ARC Centre of Excellence for Functional Nanomaterials led by Prof. Rose Amal at UNSW with the Australian Postdoctoral Fellowship (APD) in 2011. He was then promoted to lecturer (2014) and Senior Lecturer (2016) in the School of Chemical Engineering at UNSW. His research is focused on the development of novel photoactive semiconducting particles for sunlight energy conversion, including hydrogen generation from water and conversion of carbon dioxide to solar fuels. Dr. Ng has attracted more than HK$27 million from government and industries on photocatalysis research. He received the Honda-Fujishima Prize in 2013 in recognition of his work in the area of photo-driven water splitting. He was also selected as Emerging Investigator by the Journal of Material Chemistry A in 2016. In 2018, he was given the Distinguished Lectureship Award by the Chemical Society of Japan. He has published more than 120 peer-reviewed papers in internationally renowned journals such as Chem. Rev., Chem. Soc. Rev., Energy Environ. Sci., J. Am. Chem. Soc., Angew. Chem. Int. Ed., Adv. Mater., and Adv. Energy Mater. He currently has 10 papers recognized as ESI Top 1% Highly Cited Paper by Web of Science. He has attracted >7800 times of total citation to date. Dr. Ng’s works have been selected as Journal Cover and Frontiespiece for 8 times, including Adv. Mater., Adv. Energy Mater., Small, and J. Mater. Chem. A. Dr. Ng has delivered >25 keynote and invited talks at international conferences. He is also a guest-editor for special issues in Catal. Today (Elsevier), ChemPlusChem (Wiley), Particle & Particle Charaterization (Wiley) and Energies (MDPI)
