Climate change is the biggest threat faced by humankind in this century. The impact is costly and catastrophic.
A versatile solution is needed because many of these greenhouse gases (GHGs) emissions are typically disseminated, from various sources. Emissions source control is most favourable but removal from the atmosphere must be considered as well.
A promising solution is solar driven photocatalysis. Most of these GHGs (CO2, CH4, N2O, …) can be eliminated by photocatalysis transforming them into benign atmospheric gases.
However, there is little evidence to suggest large-scale applications work efficiently.
There are multiple challenges, 1) Production of undesirable species. 2) Challenging to process large enough volume of air and to evaluate the efficacy. 3) More needs to be known about the potential deactivation of photocatalyst surfaces.
This project responds to all these challenges by proposing a process intensified photocatalytic approach and developing multifunctional nanomaterials. They will allow significant and quantitative volume of airflow to be processed and, will enable reaction species, efficacy and durability to be monitored, evaluated and enhanced.
This studentship will build a rig, and aim to investigate and optimise the choice of catalysts and their operating conditions for the elimination of different target gases in urban and rural environments. It will also preliminary consider costs, durability and sustainability impacts implied in scaling up the process.
