Dr. Yun Hau Ng being interviewed in TV programme "Innovation GPS"

Associate Professor Dr. Yun Hau Ng, from the School of Energy and Environment, was interviewed in a tech-focused TVB programme “Innovation GPS (創科導航)” on the clean hydrogen energy generation and water treatment using the principle of photocatalysis. Dr. Ng and his team are developing efficient photoactive semiconductors capable of harvesting sunlight energy and converting it into chemical energy by splitting water molecule into hydrogen and oxygen. This solar hydrogen produced from water can be used as energy carrier in various industrial applications. The developed photocatalysts (photoactive semiconductors) demonstrated potential in converting wastewater into clean hydrogen as well.
The interview was aired at Channel 85 TVB Finance & Information Channel – Innovation GPS, on 9 October 2019 at 9:30 pm. The programme is available online at
