I carry out multidisciplinary research bringing microwave science and engineering to fields in which it is not conventionally used. I currently have research collaborations with departments of chemistry, physics, pharmacy, and biosciences, all taking advantage of the unique electromagnetic properties of microwaves in innovative ways. I currently have projects working on microwave catalysis for generation of clean hydrogen fuel, the destruction of plastic waste, manufacture of battery materials and new analytical and spectroscopic techniques for measuring a wide range of chemical processes.

 

Project Focus I – Hydrogen from fossil fuels: Can we decarbonise the entire hydrocarbon fuel industry?

Hydrogen is often described as the fuel of the future since its only by-product as a fuel is water. But there are major barriers to its widespread adoption. We lack cheap, safe and easily produced hydrogen storage materials and the infrastructure to support its distribution.

But in a recent discovery using microwaves, we managed to generate hydrogen from diesel and waxes with >98% purity, rapidly and on demand, with all unwanted by-products such as carbon dioxide and methane being suppressed and the only by-product being solid carbon. By this new approach, we could produce completely clean hydrogen fuel at the point of use using our existing petrochemical infrastructure.

  

Project Focus II: Clean hydrogen fuel and carbon nanotubes from plastic waste

Plastic waste is an increasing problem, with 12 billion tonnes estimated to have accumulated in landfills by 2050. Researchers have studied various ways to convert it into useful products such as fuels, synthetic oils, and carbon nanotubes, but these processes generally involve complex two-step processes requiring high temperatures and produce large amounts of CO2 as a by-product.

In recent work, we’ve demonstrated a simple one-step process for the catalytic deconstruction of plastic waste, which rapidly produces a large volume of hydrogen gas (>90% pure) leaving only a residue of carbonaceous materials, the bulk of which are carbon nanotubes. Within minutes, over 97% of the theoretical mass of hydrogen is extracted from the deconstructed plastic.
