Special Issue Information

Dear Colleagues,

In the last decade, the rapid depletion of fossil fuels has escalated the demand for renewable biomass as alternatives to chemicals and fuels. Lignocellulose, as the main component of biomass, consists of cellulose, hemicellulose and lignin. All these compounds can be catalytically converted to valuable chemicals and high-quality biofuel. Currently, considerable research efforts have been devoted to screening out efficient catalysts using specific model compounds as reaction substrates, which lay the foundation for the development of general catalysts for bio-oil upgrading. However, the complexity of bio-oil components and the repolymerization of phenolic compounds in thermal environments have augmented the difficulty of exploring efficient catalysts and related reaction mechanisms.

This Research Topic aims to highlight and collect the latest progress regarding novel nanostructured catalysts for the conversion of biomass and derivatives to valuable chemicals and biofuels. In this Special Issue, we welcome manuscripts related to the catalytic conversion of biomass and upgrading of bio-oil and model compounds. Topics of interest include but are not limited to the following:

  1. Hydrogenation/hydrogenolysis/hydrodeoxygenation of biomass and derivatives to biofuels and valuable chemicals;
  2. Catalytic oxidation of biomass and derivatives;
  3. Catalytic pyrolysis of biomass to bio-oil.

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. Catalysts is an international peer-reviewed open access monthly 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 2700 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.

In the current investigation, carbon-based solid acid catalysts were synthesized from peanut shells (PSs) and rice straw (RS) using ZnCl2 activation and concentrated sulfuric acid sulfonation. These catalysts were then employed for the hydration of pinene to produce terpineol. The research findings suggest that the natural porous structure of RS is more amenable to ZnCl2 activation compared to PSs. Furthermore, the catalysts prepared from fully activated RS by ZnCl2 (RSA-C-S) had a higher SBET and higher density of oxygen-containing groups (–COOH) in comparison with unactivated RS-based solid acids (RSC-S). The characterization outcomes revealed that RSA-C-S possesses a specific surface area of 527.0 m2/g, significantly outperforming RSC-S, which has a surface area of 420.9 m2/g. Additionally, RSA-C-S registered a higher –COOH density of 1.37 mmol/g, as opposed to RSC-S’s, with 1.07 mmol/g, attributable to the partial oxidation of internal –OH groups during activation. Experimental data from hydration tests confirmed that the catalyst’s superior performance is largely attributed to its elevated specific surface area and a high density of –COOH functional groups. Under optimal reaction parameters, RSA-C-S demonstrated unparalleled catalytic efficiency in the synthesis of α-terpineol via hydration of α-pinene, achieving conversion and selectivity rates of 87.15% and 54.19%, respectively.
