Researchers at Griffith University, led by Professor Qin Li, have made significant advancements in sustainable chemical production by developing innovative quantum materials. Their research focuses on converting methanol into ethylene glycol, a key chemical used in polyester and antifreeze production. Ethylene glycol is currently produced from petrochemicals through energy-intensive processes, but the team's solar-driven photocatalysis method offers a more eco-friendly alternative. By combining carbon quantum dots with zinc selenide quantum wells, the team has achieved a more than four-fold increase in photocatalytic activity, making the conversion process highly efficient. The byproduct of this process is green hydrogen, further highlighting the sustainability of the approach. This discovery not only leads to greener chemical production but also opens up avenues for future developments in photocatalysis, sensing, and optoelectronics. Professor Li emphasizes the importance of sustainable materials in achieving important chemical transformations and addressing challenges posed by climate change, such as zero-emission power generation and a circular economy.
