Special Issue Information
Dear Colleagues,
The search for new catalysts plays a key role in the development of risk-free chemical processes, and more generally in green chemistry. Catalytically active nanomaterials with improved activity and stability for biomass conversion have become, in recent years, an important topic in view of the transition towards a bio-based economy. In particular, it is important to study new solid acid catalysts with tailored properties in terms of both type and density of acid sites and water tolerance, as in bio-refinery reactions are carried out in the presence of water as vapor or even in liquid state.
It is recognized that the conversion of lignocellulosic materials into fuels can become an economically feasible process only if coupled with the production of valuable chemicals.
Hexoses and pentoses are the carbohydrates that represent the largest component of biomass and are widely found in almost all the biomass species. Acid-catalyzed dehydration of hexoses and pentoses is a demanding reaction due to the huge market potential of the resulting 5-hydroxymethylfurfural (HMF) and furfural products, being these products’ key intermediates in future biorefineries.
Innovative systems for organic pollutants abatement in advanced sustainable oxidative processes are a great challenge, as well. Clean water is one of the biggest concerns of future society, as the concentrations of several types of contaminants (pharmaceuticals, pesticides, and metabolites) are increasing. The main techniques applied to perform the purification of wastewater, such as adsorption by the use of activated carbon, biological treatment, and filtration, do not eliminate these contaminants completely. Therefore, novel water purification methods need to be developed. In this view, advanced oxidation processes involving the generation of reactive oxygen species (ROS), in particular, the heterogeneous photocatalysis, offer promising technology to remove most of organic contaminants.

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.
