Waste-derived carbon: structure, properties and applications
Swati Sharma

P
yrolysis or controlled heating of biodegradable and non-biodegradable polymers is an emerging technique for their safe
decomposition and possible recycle. The mixture of volatile products resulting from pyrolysis is typically collected as the
‘syngas’, which is further separated by distillation into gaseous products to be used as fuels and precursors for the synthesis of
various high molecular weight organic compounds. However, one major challenge associated with waste polymer pyrolysis
is the handling of the residual solid byproducts, often designated as ‘ash’. In our group we develop novel pathways to pyrolyze
polymers such that the solid residues are useable forms of elemental carbon rather than ashes. Depending on the surface
properties and the extent of crystallinity these carbon materials are further classified as glassy or activated. While activated
carbon, often obtained from cellulosic materials such as papers waste, is employed in various industry-scale adsorber and
filtration applications; glassy carbon is extensively used in miniaturized devices such as micro/ nano electromechanical
systems (MEMS/ NEMS), battery and supercapacitor anodes, sensors and cell culture scaffolds owing to the fact that it can be
derived from lithographically patterned polymers. This talk will be focused on various aspects of pyrolytic carbons including
(i) the structure-property relationship in pyrolytic carbons at bulk and nano-scale, (ii) influence of pyrolysis conditions on
the microstructure of resulting carbon, (iii) characterization and classification of carbon obtained from polymers of different
chemical classes, and (iv) unconventional applications of pyrolytic carbons. Pyrolysis efficiency, state-of-the-art characterization
techniques such as in situ electron microscopy will also be touched upon.
