AN ADDENDUM TO THE IBI NEWSLETTER COMPOSED EXCLUSIVELY FOR
MEMBERS
Papers in this list are from last month’s new ‘biochar’ entries in Google Scholar. Quotes are from the papers,
which are accessible through the links provided. These have been extracted by Abhilasha Tripathi PhD
Candidate, Indian Institute of Technology, Kanpur to keep the length of this addendum manageable, yet
informative enough to prompt further investigation by readers. Emphasis was placed on highlighting new findings
leading to practical application, but with the expectation that decisions will be informed by accessing the full
publication.

From the Abstract: “… boron doping significantly prolonged the lifetime of Ni/BC catalysts by interacting with Ni and the biochar support simultaneously. It is believed that boron doping lowered the gasification consumption rate of the biochar support in three ways: transforming the inherent K into more stable borates, inhibiting the desorption of CO and CO2, and forming B2O3 as the active site blocker.”

From the Abstract: “The Se/N co-doping induces a rapid cycle of adsorption-degradation for
phenol (PE). The Se/N-BC acts as an "electron transfer bridge", guiding rapid electron transfer
from PE to PMS (peroxymonosulfate) to achieve high-efficient degradation. The Se/N co-doping
facilitates the formation of graphitic N and unlocks the potential of adjacent C sites for PMS
activation, consequently boost oxidation efficiency.”

Eng. Res, February, 2022. https://doi.org/10.4491/eer.2020.648. From the Abstract: “the addition of biochar reduced efficiently the amount of H2S that initially occurred in the headspace during reactor start-up. Nevertheless, no impact on biogas- and methane yields was observed. This might be explained with an already well-working AD system without any severe disturbances, where the balancing nature of biochar did hardly count.” Wang, P, Y Sakhno, S Adhikari, H Peng, … D Jaisi - Bioresource, (2021) “Effect of Ammonia Removal and Biochar Detoxification on Anaerobic Digestion of Aqueous Phase from Municipal Sludge Hydrothermal Liquefaction.” Elsevier. https://www.sciencedirect.com/science/article/pii/S0960852421000699. From the Abstract: “The results showed that the treated aqueous phase resulted in up to 225 ml CH4/g COD.

transformation of labile Cu and Zn to the stable fraction was promoted, and the leachability and
environmental risk of them were simultaneously reduced. In contrast, CaO and Ca(OH)2 were
more favorable for the immobilization of Cu and Zn than CaCO3.”
