Special Issue Information

Dear Colleagues,

Growing consciousness of environmental issues has significantly changed the thinking of chemists working in research and design. The resulting green chemistry approach involves reducing and eliminating the generation and use of hazardous substances. Related, sustainable chemistry is of particularly high importance, stimulating the development of clean processes and technologies. It includes waste reduction, minimization of materials and energy, renewability, introduction and use of environmentally-benign reagents and efficient processes. In particular, recycling (that is the reuse of catalysts) is an important issue when considering the limited availability and dwindling supply of expensive noble metals. A long catalyst lifetime and the ability to easily recycle catalysts are highly desirable for industrial applications as well. That is, both environmental and economic considerations force the development of processes that enable the separation and recovery, as well as reuse, of catalysts. In recent years, a wide range of catalyst materials have been developed addressing these problems. Without a doubt, this topic has become a mainstream interest. Consequently, it appears to be useful to compile a Special Issue on catalyst recycling and survey various aspects of this field.

The use of single metal oxides as heterogeneous catalysts has been a partial success, because of their poor efficiency towards desired applications or rapidly-decreasing activity and reusability. The choice of metals and support materials with appropriate characteristics allow the design of mixed oxides to suit specific application needs and recyclability characteristics with little loss in activity. With the advent of multicomponent one-pot reactions (MCRs), mixed oxide composites and supported nano-composites have proved highly efficient and efficacious as catalysts to enable the reactions of many bio-active and pharmaceutically important organic moieties in high yields under moderate reaction conditions, by use of green solvents and short reaction times. Many mixed oxides and their nanocomposites have also been effectively used as catalysts and photo-catalysts for degradation of toxic/refractory pollutants from water systems.

The proposed Special Issue aims to bring together recent advances in the design and fabrication of varied nanomaterials, supports and nanocomposites and their successful application as reusable and recyclable catalysts in varied fields, with an emphasis on sustainability and green principles. The scope of these nanocomposites as recyclable heterogeneous catalysts or photo-catalysts as renewable catalysts certainly fit well into the topic.

Experts working with homogeneous (soluble) metal complexes, heterogenized (immobilized) complexes, solid heterogeneous catalysts and novel nano-composites employed as recyclable and renewable catalysts in varied reactions or industrial processes will have a great opportunity to make their results more visible. Interested readers, in turn, will find a rich source of information on various aspects and current efforts in the field, focusing on major achievements of recent years. Original research papers and reviews encompassing various aspects of recyclable catalysis are welcome.

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 papers will be 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. Molecules 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 1800 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.
