Special Issue Information
Dear Colleagues,
The use of abundant, low-cost lignocellulosic biomass to replace petroleum-based chemicals from fossil resources is a challenge of much current interest and importance. The integrated biorefinery concept of the lignocellulosic biomass conversion into fuel, chemicals, and materials is now seen as the most feasible potential way to achieve a sustainable bio-economy. The development of effective catalytic methods for selective eco-clean (green) fractionation and upgrading of the main biomass components (cellulose, hemicelluloses, and lignin) is crucial for a viable biorefining technology.
Polyoxometalates (POMs), early transition metal oxygen anion clusters, represent an important class of synthetic inorganic catalysts. Heteropolyoxometalates (free heteropolyacids and salts of heteropolyanions, HPAs), possessing properties of both strong acids with extremely high Brönsted and Lewis acidity and very power multi-electron oxidants, hold a great interest now as bi-functional catalysts for various homogeneous and heterogeneous reaction systems. The unique complex of HPA properties, such as structural and functional mobility that can be easily controlled during a rather simple and low cost synthesis, high solubility in water and various oxygen-containing organic solvents, high stability over a wide range of reaction conditions, and, finally, easy regeneration after utilization, make HPAs very attractive catalysts in biomass conversion technologies.
Significant progress has been achieved in recent years in the development and application of POM catalytic systems (both homogeneous and heterogeneous) in biomass conversion technology. This Special Issue invites original research papers covering all aspects of homogeneous or heterogeneous catalysis by POMs in the field of lignocellulosic biomass biorefinery and chemical conversion of isolated biomass components, including, but not limited to, the following topics: POM-catalyzed fractionation of biomass; POM-catalyzed oxidation reactions; POM-catalyzed hydrolysis/acid reactions; POM-catalyzed synthesis and modification of biomass components; POM catalysis of biomass conversion in green solvents; POM solid catalysts for biomass conversion; POM and product recovery during biomass conversion; new POM catalysts for biomass fractionation/upgrading; etc.

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 2200 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.
