Special Issue Information
Dear Colleagues,
The number of studies and patents dealing with traditional metal nanoparticles and non-conventional nanocatalysts is increasing tremendously in the fields of catalysis and energy.
Nano-catalysis is expected to be a fruitful area for Green Chemistry, and the increasing ability to design in the nano-state may offer expanding catalytic developments. Nanotechnologies can help to redraw old industrial processes under a “greener” approach, re-evaluating, at a small scale, the synthesis of fine chemicals or drugs for the pharmaceutical industry. By finely tuning the scalability of the process, waste minimization and the saving of energy could be important goals easily reached by modern industry.
However, to provide the maximum benefit for society and the environment, nanocatalyst recycling is mandatory and it still represents an open challenge for chemists. To this end, supported catalysts, in combination with eco-friendly solvents (viz. ionic liquids, supercritical fluids, fluorous phases, water, etc.), can represent a valid and green alternative to homogeneous catalysis in classic solvents.
The need for energy is increasing worldwide, while, at the same time, fossil resources are decreasing tremendously. Industrial economies, as well as emerging countries, need to produce, transport, store, and use energy with increased efficiency.
In recent years, there have been tremendous efforts focusing on the development of new and cost-effective electrochemical technologies and materials. Novel nanophases, electrodes, and electrolyte materials are extensively investigated, as well as electrode and device configurations, to improve energy production, storage, and conversion technologies, employing electrochemical methods. In particular, electrodeposition is well known for depositing metals and metallic alloys at the industrial level, with a wide range of applications, from large area surface treatments to most advanced electronic industries. The electrodeposition of materials represents a new challenge, not only from an academic point of view, but also from an economic one, as this method presents interesting characteristics for large areas, such as low cost, and generally low temperature and soft processing of materials. The great interest in nanometer-scale materials systems arises from the fact that their optical, electrical, magnetic, or mechanical properties are often very different from the same materials in the bulk phase, and, more importantly, they can be tuned by changing the physical dimensions of the material. The procedure can be extended to the deposition of metals with the aim of limiting the amount of precious metals in electrocatalysis.
This Special Issue of Molecules focuses on the use of nanocatalysts and nanotechnologies in a wide range of catalytic organic reactions, electro-catalysis, and energy applications.
Suitable topics include, just to cite a few:
- Traditional carbon-carbon or carbon-heteroatom bond forming reactions (e.g., Heck, Suzuki, Stille, Sonogashira, Ullmann, Glodberg, and so on);
- Synthetic approaches, based on the green chemistry principles: atom-economy, dematerialization, energy saving, raw material diversification, green solvents, etc.;
- Detoxification of PCBs, fixation and chemical valorization of CO2, and so on;
- Nano-metal catalyzed processes and technologies for recycle/conversion of plastics, biomasses and wastes;
- Development, characterization, device technology and performance of nano-metals and non-conventional nanocatalysts in: fuel cells, batteries, supercapacitors, electrocatalysis, etc.;
- Surfaces modified for Energy Devices
Truly multidisciplinary studies providing a bird’s-eye-view of nanocatalyst features, including its development/synthesis and its analytical chemical and morphological characterization, as well as applications and structure-performance level correlations, are strongly encouraged.

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. Molecules 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 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.
Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
