3D printing approaches for electrocatalysis

Supervisory team: Dr. Ali Jalili, Dr. Emma Lovell, Dr. Daiyan Rahman, and Prof. Rose Amal

Description: 

Additive manufacturing, or 3D printing, is a family of techniques that enable the fabrication of a solid object from a computer-aided design (CAD). 3D printing is becoming increasingly dominant in the field of advanced material processing and applications. Many of the traditional techniques are time-consuming and complex, requiring specialist equipment and training, as well as being hard to reproduce. On the other hand, 3D printing provides materials chemists and engineers with the ability to design, prototype and print geometrically complex functional devices that integrate nanoscale performance, biological property, electroactive, photoactive and catalytic functionalities.

In a general aspect of electrocatalysis, the performance of an electrocatalyst is determined by its intrinsic activity, the accessibility of active sites and the electron transfer efficiency. Therefore, it is essential to fine-tune the structural porosity or provide tunable hierarchical microstructures which will enlarge the surface area, benefit the exposure of active centres and facilitate the transport of reactive agents to the surface of the catalyst.

3D printing for electrocatalysis

 

The host of this project, Particles and Catalysis Research Group (PARTCAT), is a leading (photo(electro)) catalysis research group within the School of Chemical Engineering at the University of New South Wales (UNSW). The student will have access to a state-of-the-art high-resolution 3D printer that can print a wast range of nanomaterials, polymers, hydrogels and catalysts. Catalysts will be modified over this project for efficient electrochemical reactions such as nitrogen conversion to ammonia or CO2 reduction to value-added chemicals.

 

Suitable for: Chemical Engineers and Industrial Chemistry

 

Level of difficulty: Challenging
