Special Issue Information

Dear Colleagues,

Design for energy efficiency is one of the principles of green chemistry. According to this principle, energy requirements should be minimized and should be considered for their environmental and economic impacts.

Catalytic oxidation reactions using energy-efficient techniques is a growing research area. To fulfil the green chemistry criteria and to develop sustainable catalytic oxidation processes, it is highly important to use energy-efficient methodologies, e.g., microwave-assisted irradiation, thermoplasmonic-induced reactions, ultrasound, and photo-induced reactions. Catalytic reactions under homogeneous, heterogenous, or supported heterogenous conditions can be explored for this purpose. Kinetic studies, theoretical calculation, and illustrations of mechanisms can also be a part of this topic.

The main goal of this Special Issue is to combine a variety of new and original research results on energy-efficient catalytic oxidation methods.

New and original research studies and review articles on this topic 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 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.

Rhenium nanoparticles (Re NPs) supported on Norit (activated carbon—C) and graphene (G) were prepared by a solvothermal method under microwave irradiation (MW). The synthesised heterogeneous catalysts were characterised and tested as reduction and oxidation catalysts, highlighting their dual catalytic behaviour. In the first case, they were used, for the first time, to reduce 4-nitrophenol, in aqueous medium, under MW irradiation. Re catalysts were easily recovered by centrifugation and recycled up to six times without significant activity loss. However, the same Re catalysts in MW-assisted oxidation of 1-phenylethanol with no added solvent experienced a significant loss of activity when recycled. The higher activity of the rhenium nanoparticles supported on graphene (Re/G) catalyst in both reactions was assigned to the higher dispersion and smaller particle size of Re NPs when graphene is the support.

In the current research study, iron-zinc co-doped TiO2 was reported as an energy efficient material for the degradation of DIPA and inactivation of E. coli and S. aureus under visible light irradiation. In addition, molecular docking simulation was performed to provide further insight into possible targets for inhibiting bacterial development. The synthesized nanocomposites were screened and optimized for different synthesis and reaction parameters. The physicochemical properties of the synthesized nanocomposites were evaluated through different characterization techniques. The wet impregnation (WI) approach was among the most successful methods for the synthesis of Fe-Zn-TiO2 nanocomposite (NC) utilizing anatase titanium. Moreover, 66.5% (60 min reaction time) and 100% (190 min reaction time) chemical oxygen demand (COD) removal was obtained through optimized NC, i.e., 0.1Fe-0.4Zn metal composition and 300 °C calcination temperature. The energy consumption for the best NC was 457.40 KW h m−3. Moreover, 0.1Fe-0.4Zn-TiO2-300 was more efficient against S. aureus compared to E. coli with 100% reduction in 90 min of visible light irradiations. Furthermore, 0.1Fe-0.4Zn-TiO2-300 NC showed that the binding score for best docked conformation was −5.72 kcal mol−1 against β-lactamase from E. coli and −3.46 kcal mol−1 from S. aureus. The studies suggested the Fe-Zn in combination with TiO2 to be a possible inhibitor of β-lactamase that can be further tested in enzyme inhibition studies. Full article
