Special Issue Information

Dear Colleagues,

Catalysis is incredibly important for sustainable development, energy production, environmental protection, and water purification, among others, since almost 90% of the chemical products generated by the industry are obtained through catalytic processes. Carbon materials have attracted enormous interest as catalysts and catalyst support in different fields, owing to their outstanding chemical, mechanical, and thermal-stable properties. In addition, these materials can be very versatile since their properties can be modified, such as surface area and surface chemistry. However, some carbon-based catalysts can present disadvantages, such as preparation methods with low yield which it is necessary to optimize, or low catalytic activity and/or deactivation with reaction time.

This Special Issue is devoted to exploring new advances in synthesis methods, characterization, and applications for carbon-based catalysts. The aim is to compile the current state of knowledge and shows the path of current research in the field of carbon-based catalysts. Mainly, complete experimental studies of synthesis, characterization, and evaluation of catalytic activity will be of greater interest, focusing on a deep cause–effect study of the preparation method, the physical–chemical properties of the prepared catalysts, and their catalytic activity in interesting processes.

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.

The aim of this study was to synthesize chemically activated carbons from different agricultural residues, i.e., pistachio shell (PS), bitter orange peel (OP), and saffron petal (SP), and subsequently to use them as supports for loading a Ni catalyst. Supercritical water gasification of bio-oil was applied to investigate the catalytic performance of the resulting catalysts. The physicochemical properties of the activated carbon (ACs) and the catalysts (Ni/ACs) were characterized with BET, XRD, XPS, TEM, and TPD. The adsorption results showed that the ACs developed considerable pore structures, containing both micro- and mesopores, which was validated by the well-distributed active phases on the supports in the TEM images. Furthermore, it was found that the BET of AC(PS) was 1410 m2/g, which was higher than that of AC(OP) (1085 m2/g) and AC(SP) (900 m2/g). The results obtained from XRD mainly indicated the presence of the nickel phosphides phases, which was confirmed with the XPS and TPD analyses. The catalytic tests showed that by raising the process temperature, the total amount of gas and hydrogen increased. Furthermore, Ni/AC(PS) showed a superior catalytic activity. The highest total gas amount (i.e., 7.87 mmol/g bio-oil), together with 37.2 vol.% H2, was achieved using Ni/AC(PS) with a 1:10:100 catalyst:bio-oil weight ratio and a mass ratio of 1:10 (bio-oil/water) at T = 550 °C.
