Internship | Photothermal design for light-driven sustainable chemical processes

Driven by the global aspiration to achieve a CO2-neutral society, the conversion of CO2 to higher energy species such as methane (CH4) has recently grown into a significant research field. To achieve a sustainable methanation process, the sunlight driven nanoparticle enabled photocatalysis reaction has shown promising results. Nanoparticle (NP) catalyst is an important ingredient: it is an efficient light absorber and varying its size and load directly affects the chemical reaction rate. In this project, we will study the photothermal effect of such NPs and quantify various contributing factors.

Conventionally, the methanation process is performed in dark and catalysed by supported metal catalysts (e.g. Ni, Ru, Rh) and requires thermal activation at temperatures between 300°C and 500°C. Instead of heat, sunlight would be an appealing alternative. Particles of nano-size are good absorber of light and transfer the absorbed energy into heat. The photothermal effect is a complex multi-physical problem. In this project, we will orderly model the optical and the induced heat transfer phenomena. The NPs have strong resonance at certain wavelengths, which is known as Plasmon resonance. The powerful catalyst NPs usually display a weak plasmon resonance, whereas the strong plasmonic metals are weak catalyst. Special attention will be paid to the plasmonic effect on the photothermal efficiency. Furthermore, the collective photothermal effect of large quantity of NPs will be studied, especially their impact on reactor design. The results of the this project will contribute to shed light on the mechanism of the photocatalytic reaction and to promote sustainable energy systems.

• Master level study on physics;
• Knowledge on optics preferably;
• Experience in computation tool and language such as, Matlab / Python
• Hands-on mentality
