A Solution to Global Warming and Climate Change

Invention Number: 
2015_042
The environmental consequences of greenhouse gas emissions, including carbon dioxide (CO2) as the main component, are now widely recognised as falling somewhere between very significant and catastrophic. UNSW Researchers have found a possible solution !

 Our Technology

 

CO2 capture is one of the most pressing issues for reduction of greenhouse gas emissions. UNSW Researchers have identified several nanomaterials and a method which overcomes typical CO2 capture issues with high temperatures and kinetics. Our CO2 capture technology allows for controlled, rapid uptake and storage of CO2 molecules as well as voltage controlled release at moderate temperatures.

 

 Key Benefits

  • Lightweight, compact, safe CO2 capture

  • Great kinetics – voltage controlled capture and release

  • Low desorption temperature

  • High selectivity from a gas stream containing other molecules such as N2, H2, H2O

  • No Catalysis

  • Non-explosive

  • Cost effective

The Opportunity

UNSW is seeking a partner to work with our with our inventors to develop prototypes and /or licence this invention.

Scientific and Technical Data 

In order to capture CO2 as a fuel source, a number of parameters have to be met.

These include:

  • Good kinetics for loading

  • Low desorption temperature

  • Reversible loading / unloading

  • High selectivity from a gas stream containing other molecules such as N2, H2, H2O

  • Low toxicity

  • Non-explosive

  • Low cost

  • Light weight

Through a computational design approach we have identified several experimental available materials and a method to capture and controllably release CO2 gas which complies with all of these parameters. Our patented technology “Electrocatalytic Gas Capture” allows for controlled, rapid uptake and storage of CO2 molecules as well as voltage controlled release at moderate temperatures.  

Hybrid boron nitride and graphene nanosheets (hybrid BN/G): An experimentally feasible strategy to charge up the wide-gap hexagonal boron nitride (h-BN) for charge-controlled switchable CO2 capture. That extra electrons might be effectively transferred from the high mobility graphene layer into the surface h-BN layer such that CO2 capture/release can be simply controlled and reverse by switching on/off the charge states of hybrid BN/G system.

Good electrical conductivity and high electron mobility of the sorbent materials are prerequisite for electrocatalytically switchable CO2 capture.Conductive graphitic carbon nitride (g-C4N3) as an ideal material for electrocatalytically switchable CO2 capture.
