11569365. Given that this metal catalyst could be a compound of commonly occuring elements such as managese and iron, isn’t it possible that hydrothermal vents are the route for naturally occuring abiotic precursors to hydrocarbon deposits such as anthracite and methane? RMIT researcher Dr Torben Daeneke said converting CO2 into a solid could be a more sustainable approach. I am interested in this research, as I have been raising the question of whether this process can be used at those hundreds of thousands of subsea thermal vents that give out as much ‘free’ energy as the average power station, at very high pressures and temperatures. The pQA portable quadrupole analyzer for gas analysis in water can be used in field applications such as at riverbanks and on boats. Registered Office: Mark Allen Group, St Jude's Church, Dulwich Road, London, SE24 0PB “To date, CO2 has only been converted into a solid at extremely high temperatures, making it industrially unviable. respect, liquid-metal (LM) catalysts have been demonstrated to have a critical advantage over conventional catalysts. Heat a eutectic metal alloy in a saucepan on a high flame. (Image credit: UNSW). All comments are moderated. Substances that show such behavior are called eutectic. Do you have a review, update or anything you would like to add to this news story? Geoff Pocock, Managing Director and Founder of the Hazer Group talks to AZoCleantech about how the Hazer Process is producing clean hydrogen with Near-Zero Carbon Emissions. The research was conducted at RMIT’s MicroNano Research Facility and the RMIT Microscopy and Microanalysis Facility. To convert CO2, the researchers designed a liquid metal catalyst with specific surface properties that made it extremely efficient at conducting electricity while chemically activating the surface. Professor Kourosh Kalantar-Zadeh, School of Chemical Engineering, UNSW. There this new-coal could be burned to release energy and also the now-valuable CO2, which the oceans will reabsorb and recycle. But hey! Professor Kalantar-Zadeh received the esteemed Australian Research Council (ARC) Laureate Fellowship, which awards funds for further research into liquid metals for another four years. Nature will tend to her own garden if we allow her to. Metals such as tin and bismuth are accessible to many people around the world. Also Coal (a Hydrocarbon) and Graphite (pure carbon) are not the same thing! While it is an interesting technique, what is the carbon footprint of producing the “Liquid Metal”? Recently, LMs acquired a place in catalysis, with a reputation often synony-mous with interesting properties and a remarkable ability to break trade-offs between homogeneous and heterogeneous catalysis. What are the highest-paid engineering jobs in the UK? He added, “While the most famous liquid metal—mercury—is well known to be hazardous, a liquid metal like gallium is completely non-toxic, and meltable at or near room temperature, where we can use it to transform one material to another at very low input energies. This is in direct contravention of Hess’s law, so the researchers must be disingenuous at best. Anyone with a shaker and a cooktop at home in their kitchen can make catalysts that can be used for CO2 conversion, cleaning water and other pollutants. People should just consider how easily, cheaply and with so little need for advanced technology that they can be processed and transformed into useful materials such as catalysts. “The process also produces synthetic fuel as a by-product, which could also have industrial applications.”.

Professor Kalantar-Zadeh and coworker Dr Jianbo Tang demonstrated that when an alloy of tin and bismuth was heated, the metal melted to a point considerably lower than when each metal was heated separately. Technologies for carbon capture and storage (CCS) involve compressing CO2 into a liquid form, transporting it to a suitable site and injecting it underground but implementation has been hampered by engineering challenges, economic viability and environmental concerns about possible leaks from the storage sites. “By using liquid metals as a catalyst, we’ve shown it’s possible to turn the gas back into carbon at room temperature, in a process that’s efficient and scalable. “While more research needs to be done, it’s a crucial first step to delivering solid storage of carbon.”. The collaboration involved researchers from Germany (University of Munster), China (Nanjing University of Aeronautics and Astronautics), the US (North Carolina State University) and Australia (UNSW, University of Wollongong, Monash University, QUT).

They can do this by using a combination of liquid metals like gallium, indium, bismuth and tin in alloys that can be melted under 300°C on a cooktop or in an oven. But by themselves, both bismuth and tin have melting points above 200 °C. Better to stop burning coal in the first place. Understanding the energy required to drive this process would have been very helpful. How’s that for an eco-dream? The mechanism can also work vice versa. Gallium, tin, and bismuth in the liquid form are used as electrodes to convert CO2 into useful byproducts.
