New methods for reducing air pollution and generating solar fuels developed by scientists from SEE offer practical solutions to the energy shortage, environmental issues, and related public health risks.

The research has been generated by two projects led by Dr. Yun Hau Ng, Associate Professor, and Dr. Jin Shang, Assistant Professor, respectively, in SEE. The research has been published in the top chemistry journal Angewandte Chemie.

Dr. Ng and his team have designed a new solar-powered catalyst that can convert carbon dioxide (CO2) into methane fuel through artificial photosynthesis. Their work is published in a paper titled “Metal-Organic Frameworks Decorated Cuprous Oxide Nanowires for Long-lived Charges Applied in Selective Photocatalytic CO2 Reduction to CH4”.

The other study, carried out by the team led by Dr. Shang, aims to control pollution resulting from nitrogen dioxide (NO2), a major roadside pollutant causing photochemical smog and damage to the human respiratory tract. The team revealed a new class of robust adsorbent materials for capturing ambient NO2 in a paper titled “Transition‐Metal‐Containing Porphyrin Metal–Organic Frameworks as π‐Backbonding Adsorbents for NO2 Removal”.
