Green hydrogen production from solar water splitting has attracted a great deal of interest in recent years because hydrogen is a fuel of high energy density. A research team led by Dr. Yun Hau Ng, Associate Professor, discovered the quantum confinement effect in a photocatalyst of a 3D-ordered macroporous structure. The quantum confinement effect was found to enable hydrogen production under visible light. The findings offer an option for addressing energy and environmental challenges. This study represents a fundamental step in understanding charge transport in metal oxide semiconductors and highly ordered porous structure.

Their findings were published in the scientific journal ACS Energy Letters, titled “Unveiling Carrier Dynamics in Periodic Porous BiVO4 Photocatalyst for Enhanced Solar Water Splitting”.
