Sustainability in Catalysts Research and Nanotechnology

Dear Colleagues,

Because of the unique qualities of nanomaterials (NMs) that make them attractive for a wide range of sustainable applications, the term nanotechnology (NT) has gained increased attention among scientists, academics, and even industrialists in recent decades. NMs are nanoscale materials with at least one dimension. The nanoscale (ns) ranges from 1 to 100 nm, and a nanometre is one billionth of a metre (10-9 m). At these levels, extraordinary optical, mechanical, electrical, and other sustainable properties emerge. Because of these emergent properties, NMs have a wide range of potential applications in sustainable electronics, medicine, and a variety of other fields.

NT confronts scientists and engineers as a nascent and quickly evolving subject. Researchers working in the realm of NT encounter a number of fresh tasks linked to nanostructures (NSs) and sustainable nanomaterials (NMs). The most pressing concerns are learning more about the properties of materials at the nanoscale and figuring out how to integrate these NSs with macroscopic systems. Because of the small size and difficulty of NSs, the development of novel dimension technologies has become even more intriguing. The key problems for the application of NT include improving efficiency, reliability, safety, lifetime, sustainability, and, most significantly, lowering the costs of NMs to make them appropriate for various sustainable device applications.

The studies invited to this Special Issue should have a focus on the recent development of sustainable nanomaterials synthesis via new methods, new experimental conditions, and new sustainable technology-related modifications. Although there is a wealth of scholarly knowledge and experience in this area spanning a wide range of disciplines, many of the materials synthesized lack purity and are unsuitable for applications. This issue will serve to augment information about sustainable materials synthesis, characterisation, and effective utilization for some sustainable applications that are directly beneficial to society. The Special Issue will also be helpful for interdisciplinary collaboration.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Materials synthesis by new sustainable methods and their characterization;
• Development of nanomaterials for sustainable effective environmental remediation;
• Semiconductor photocatalysis for sustainable energy application;
• Sustainable nanoscience and technologies;
• Nanomaterials for sustainable electrocatalytic applications;
• Nanomaterials for sustainable biological applications;
• Catalytic-based organic synthesis;
• Engineering aspects of the sustainable materials research.

We look forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.

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 2400 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.
