Special Issue Information

Dear Colleagues,

Catalysis is at the heart of many industrial chemical processes. Enzyme-catalyzed reactions are highly efficient in terms of selectivity, but very often catalysts (or products) cannot be easy recovered. On the other hand, heterogeneously catalyzed reactions can allow easier and more efficient separation of high value products from the catalyst. However, the selectivity and conversion rates are often limited by the multiphasic nature of these systems and/or variations in active site distribution. For these reasons, the development of highly selective and efficient hybrid catalysts is extremely necessary. Hybrid organic–inorganic materials have attracted much attention in the last years due to their wide range of applications. They face the unsolved need of the fine chemical industry to find new and more efficient catalytic systems as possible alternatives to abandon stoichiometric processes still in use. The inspiration for catalysis assembly mainly comes from nature, which has found an ingenious way to perform cascade reactions in the environment of the cells over enzymes. Thus, the development of strategies towards advanced complex hybrid architectures using pre-organized or self-assembled structures is a main challenge of hybrid catalysis. This review focuses on the synthesis, characterization and application of hybrid catalysts. We emphasize the factors that have to be considered in order to understand their catalytic activity. This is because a better understanding of catalytic materials is now an essential tool not only for the choice of the best preparation route in the synthesis of fine chemicals for industry, the synthons for pharmaceutical applications and new bio-based compounds. This Special Issue of Sustainability is seeking papers that can demonstrate new developments in hybrid catalysis and processes. We are looking for works dealing with enzymes and/or the immobilization of homogeneous catalysts and their use in sustainable processes, as well as for new advances in hybrid processes and reactor engineering.

Manuscript Submission Information

Manuscripts should be submitted online at 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 2000 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.

Every year, a large amount of residual agroindustrial waste has been generated and only around 10% is in fact reused. The development of new strategies for biomass valorization is important to add value to these commodities, since biomass is an excellent alternative feedstock to obtain chemicals of interest from renewable resources. The major compound of pyrolytic treatment of lignocellulosic biomass is levoglucosan (1,6-anhydroglucopyranose), an anhydro-sugar that can be transformed into glucose and is greatly valued in the most diverse industrial sectors as a surfactant, emulsifier, or even a lubricant. In this work, levoglucosan was acylated by lipase-catalyzed transesterification in acetonitrile with great conversions and selectivities with different acyl donors such as ethyl esters of lauric, palmitic, stearic, and oleic acids prepared in situ in an integrated strategy mediated by commercial lipases Novozym435 (N435), PSIM, and the home-made biocatalyst CaLB_epoxy. As a result, all biocatalyst generated mostly monoesters, with N435 being more selective to produce lauric esters (99% at 50°C) and PSIM to produce oleic esters (97% at 55 °C) while CaLB_epoxy was more selective to produce oleic esters of levoglucosan (83% at 55°C). This is the first report in the literature on the production of high selectivity levoglucosan esters. Full article
