Special Issue Information

Every two years, the Catalysis Division of the Chemical Institute of Canada organizes a high-quality symposium, linking the catalysis community in Canada and many renowned researchers from both academia and industry around the world. The CSC 2022 is being held in Vancouver from 15–18 May with the theme: Catalyzing a Greener Future.

Although Catalysis is a general field, our endeavour is to find more environmentally friendly catalysts as well as to propose catalytic pathways to produce our goods in ways which minimize environmental impact for the benefit of our society. It would allow us to be more techno-economically efficient while preserving our future and thus would contribute to sustainability alongside tackling the anticipated phenomenal increase of our world’s need for energy and value-added processing.

In order to increase/optimize the positive impact of this symposium, the organizing committee and the open-access periodical Catalysts joined forces to produce a Special Issue, which will include the best quality contributions in the following areas:

  • Catalysts/Nanocatalysts Synthesis, Characterization, Fundamentals & Mechanisms
  • Industrial Applications of Catalysis
  • Catalytic Reaction Engineering – Reactors Configurations and Scale-ups
  • Catalysis for Bitumen/Heavy Oil Upgrading and Petroleum Refining
  • Electrocatalysis for Energy Sustainability
  • Photocatalysis
  • Operando Catalysis and Advanced Characterization of Working Catalysts
  • Biocatalysts for Fuels and Chemicals
  • Catalysis for Bio-oils Production and Upgrading
  • Advances in Selective Catalytic Reduction for NOx Emission Control
  • Catalysis for Coal Conversion
  • Catalytic Materials for Fuel Cells, Electrolysis, Supercapacitors and Batteries
  • Catalytic Conversion of Sugars and Glycerol into Chemicals
  • Catalysis for the Environment

The submission for the Special Issue of Catalysts will open till 15 September 2022. Please consider to submit a high quality manuscript for this Special Issue related to your presentation at the CSC 2022.

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 steam reforming of dimethyl ether (SRD) has been proved to be one of the most promising routes for on-site H2 production. However, the two-step consecutive nature of the SRD reaction makes the design of an efficient bifunctional catalyst a challenge. Herein, a series of Cu incorporated into amorphous silica–alumina (Cu–ASA) as integrated bifunctional catalysts for SRD were synthesized by the single-step complex decomposition method, and ammonium carbonate was confirmed to be an effective complex agent for dispersing Cu in ASA. The results indicated that the initial conversion of dimethyl ether and a H2 yield higher than 90% were achieved at 300 °C over the optimal catalyst. More importantly, a slightly decreased SRD performance with increasing time-on-stream was mainly caused by Cu sintering, and the synergetic effect between ASA and Cu played a crucial role in determining the activity, hydrogen yield, and stability of the integrated Cu–ASA bifunctional catalyst for SRD. These findings are helpful to develop a high-performance integrated bifunctional catalyst for the SRD reaction. Full article

Pt/W/SBA-15 catalysts (with Pt-loading = 0.5–4 wt% and W-loading = 1 wt%) prepared by the sequential impregnation method were evaluated for selective C–O cleavage of erythritol and glycerol in an aqueous medium. The Pt and W particles dispersed on SBA-15 approached close proximity at higher Pt loadings and afforded synergistic enhancement in C–O hydrogenolysis activity/selectivity. 1,4-Butanediol yields of 30.9% (at 190 °C, 50 bar H2 and 24 h) and 1,3-propanediol yields of 34.4% (at 190 °C, 50 bar H2 and 12 h of reaction) were obtained over these catalysts. Pt nanoparticles (facilitating dissociative H2 adsorption and spillover) and W (present as acidic oligomeric WOx species; activating and coordinating the polyol via 1°-OH group) worked in tandem for the selective hydrogenolysis of polyols yielding terminal diols of industrial demand.

In this review, we aim to give an overview of the use of the Borrowing Hydrogen (BH) methodology with bio-based alcohols. This methodology only forms water as a by-product, thus providing a sustainable way to amines, which have a large range of applications. This process is of particular interest when related to biomass due to the high abundance of alcohol functions in natural compounds. However, natural compounds often comprise multiple chemical functions that can change the reactivity of the substrate. This comprehensive review, comprising both homogeneous and heterogeneous catalysts, aims at summarizing the recent advancements in biomass amination for every class of substrate, highlighting the key parameters governing their reactivity and the remaining scientific hurdles. Even though most substrates have successfully been converted into the corresponding amines, reaction selectivity and functional group tolerance still need to be improved. Full article
