Special Issue Information

Dear Colleagues,

The primary aim of this Special Issue is to increase dissemination of the research activities conducted within the GreenCarbon European Training Network (project H2020-MSCA-ITN-721991), including the final conference held in Zaragoza (9-12th March 2021) and entitled International Symposium on Functional Biomass-Derived Carbon Materials (GreenCarbon 2020). The most relevant contributions from attendees to this event (from both inside and outside the framework of the abovementioned research project) are expected to be submitted.

The topics covered include but are not limited to:

  • Production and characterization of biomass-derived carbons through thermochemical processes;
  • Synthesis of biomass-derived porous carbons (and composites) and their application in adsorption, catalysis and electrochemical energy storage;
  • Biomass-derived carbons for soil conditioning (biochar) and related environmental benefits;
  • Other emerging applications of biomass-derived carbons (e.g., in direct carbon fuel cells, as reductants in metallurgical industry, in cementitious composites, carbon quantum dots, etc.).

We look forward to your submission.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Fuel cells, batteries and supercapacitors are critical to meet the rising global demand for clean, sustainable energy. Biomass-derived activated carbon can be obtained with tailored properties to fulfil the extensive need for low-cost, high-performance, catalyst and electrode materials. To investigate the possibility of nanoporous nitrogen-doped carbon materials as catalysts in fuel cells and electrodes in lithium-ion batteries, biomass precursors were thermochemically activated with NaOH at 800 °C, nitrogen was introduced using dicyandiamide and doping was performed at 800 °C. The chemical composition, porous structure, texture and electrochemical properties of the obtained materials change depending on the biomass precursor used. It has been found that the most promising precursor of the obtained materials is wood char, both as an oxygen reduction catalyst in fuel cells, which shows better properties than the commercial 20% Pt/C catalyst, and as an anode material in Li-ion batteries. However, catalysts based on black liquor and hybrid material have comparable properties with commercial 20% Pt/C catalyst and can be considered as a cheaper alternative. Full article

Wheat-Straw-Derived Activated Biochar as a Renewable Support of Ni-CeO2 Catalysts for CO2 Methanation

Abstract
Ceria- and urea-doped activated biochars were used as support for Ni-based catalysts for CO2 methanation purposes. Different materials were prepared and tested to find the best catalytic formulation. After several CO2 methanation experiments—carried out at 0.35–1.0 MPa and 300–500 °C—it was [...] Read more.
Ceria- and urea-doped activated biochars were used as support for Ni-based catalysts for CO2 methanation purposes. Different materials were prepared and tested to find the best catalytic formulation. After several CO2 methanation experiments—carried out at 0.35–1.0 MPa and 300–500 °C—it was found that the most suitable catalyst was a wheat-straw-derived activated biochar loaded with 30 wt.% of CeO2 and 20 wt.% of Ni. Using this catalyst, a CO2 conversion of 65% with a CH4 selectivity of 95% was reached at 1.0 MPa, 400 °C, and 13,200 h−1. From the study of the influence of the gas hourly space velocity, it was deduced that the most likely reaction mechanism was a reverse water–gas shift reaction, followed by CO hydrogenation. N-doping of the carbon support as an alternative to the use of ceria was also investigated. However, both CO2 conversion and selectivity toward CH4 values were clearly lower than those obtained for the ceria-containing catalyst cited above. The outcomes of this work indicate that a renewable biomass-derived support can be effectively employed in the catalytic conversion of CO2 to methane. Full article
