Carbonisation of biomass-derived chars and the thermal reduction of a graphene oxide sample studied using Raman spectroscopy

John McDonald-Wharry, PhD candidate from Waikato U. has kindly provided a link to a newly released paper on his work. He will be presenting related to this at the NZBRC workshop on 4 July with the title “Studying Carbonisation with Raman Spectroscopy”.

Based on previous discussion with John, this new testing method opens the door to measuring peak production temperatures on post-production samples of biochar – an important process condition to know when selecting biochars (John – please feel free to chip in with a better layman description!).

Carbonisation of biomass-derived chars and the thermal reduction of a graphene oxide sample studied using Raman spectroscopy — 1 Comment

  1. An open call for samples for a Raman spectroscopy survey of biochars and other carbonised biomass.

    To help validate and extend this methodology I should like to apply the technique to a wide range of biochars from diverse backgrounds and I am seeking your assistance for this.

    The plan is to have a broad range of people or groups (including companies, hobbyists, academic researchers, and other interested groups) send a few char samples each to me at the University of Waikato.

    If you are able to participate in this study there will be no cost attached other than conveying your sample to the University of Waikato. In exchange for this the sample will be analysed by Raman spectroscopy and you will receive a copy of the results and an estimate of the “effective heat treatment temperature” based upon our current model.

    The priority will be given to samples sourced from New Zealand. However, international samples will also be welcome, especially if they are well-characterised ones with scope to be used as global reference materials.

    Further details of this project for those interested in being involved, will be distributed by email.
