Dear Colleagues,

Under the goal of carbon neutrality, the conversion and utilization of biomass energy have drawn increasing attention. However, the processing efficiency should be further improved to obtain higher-quality products and reduce carbon emissions. Multifield enhancing technology (i.e., electromagnetic field, photoelectric field) shows the potential to optimize biomass conversions, and is becoming a popular research topic.

The aim of this SI is to promote the R&D of biomass conversion with the assistance of multifield enhancement. Reaction pathways can be changed under multifield collaboration, and the in-depth mechanism should be revealed. The sustainability of the process, including the motivation and maintenance of the multifield, the stability of the process, and the economic and environmental benefits, should be evaluated, and these topics all lie within the scope of this SI.

In this Special Issue, original research articles and reviews are welcomed. Research areas may include (but are not limited to) the following:

• Biomass gasification/pyrolysis and product upgrading with the assistance of microwaves;
• Biomass to hydrogen conversion via photothermal-assisted conversion;
• Highly efficient pretreatment of biomass under multifield effect and system evaluation.

We look forward to receiving your contributions.

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.
