Sensor CDT Student creates carbon-based structure with multi-level hierarchy in a simple way

last modified May 15, 2018 01:54 PM

Sensor CDT student, Tiesheng Wang (王铁胜), found a simple way to transform metal-organic frameworks (MOFs) to carbon-base structures with ordered multilevel hierarchy, termed as “nano-diatom” (named for the morphological similarities with the naturally existing diatomaceous species). The metamorphosis is enabled by adding salts (metal-containing compounds) into the MOF followed by a high-temperature carbonisation process.

Tiesheng is a PhD candidate supervised by Dr Stoyan Smoukov and Dr R Vasant Kumar, and working closely with Professor Anthony Cheetham. Together with Dr Hyun-Kyung Kim, they have demonstrated one of the nano-diatoms as a superior carbon-based anode material for fast-charging lithium-ion battery. They published their work in JACS (Journal of the American Chemical Society) recently: http://doi.org/10.1021/jacs.8b02411

In the paper, Tiesheng and his collaborators from University of Cambridge, Queen Mary University of London and Max Planck Institute for Solid State Research proved that the transformation can be controlled by the initial chemical composition (i.e. MOF and metal-containing compound used). They also realized that the discovery can be applied as a working strategy for functionalizing the carbon not only for energy storage but also for catalysis and chemical sensing. Tiesheng, Stoyan and Hyun-Kyung have filed a relevant patent.

Since there are thousands of MOF and metal-containing compounds available, the discovery and its following work on understanding the formation mechanisms will enable the design of future carbon-based functional materials. The work is highlighted in the following press release:

Sensor CDT students at Creativity Sandpit with Imperial and Warwick CDTs

May 22, 2018

A Creativity Sandpit took place on 15-17 May 2018 at Easthamstead Park near Bracknell in a big old mansion and about 30 brilliant minds working together. It was organised by the High Performance Embedded and Distributed Systems (HiPEDS) CDT at Imperial College. In addition to HiPEDS and Sensor CDT, the Warwick Urban Science CDT joined in as well.
