Special Issue Information

Dear Colleagues,

Heterogeneous catalysis is a very important process to the world’s economy because it can economically, efficiently, and environmentally convert raw materials into valuable chemicals and fuels. It has been estimated that 90% of all chemical processes use heterogeneous catalysts. Over the past decades, heterogeneous catalysts have had numerous industrial applications in various areas, such as in chemical, food, and pharmaceutical industries. New applications of heterogeneous catalysis are emerging in areas such as fuel cells, green 

chemistry, nanotechnology, and biorefining/biotechnology. Indeed, continued research into heterogeneous catalysis is necessary to address the increasingly complex environmental and energy issues in our industrialized society. This Special Issue will cover topics including, but not restricted to, the recent advances in heterogeneous catalysis for energy applications such as hydrogen energy, the formic acid economy, the methanol economy, the ammonia economy, etc., as well as environmental applications such as carbon-neutral technologies, sustainability, pollutant removal, etc.

Considering your prominent expertise in this active field of research, we would like to cordially invite you to submit an article to this Special Issue. Short communications, full research articles, and timely reviews are all 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. 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.

This work evaluates the effect on the adsorption and desorption kinetics of propene and toluene (used as probe molecules for vehicle cold-start emissions) of the isomorph framework substitution of Zr, W, and V on commercial ZSM-5 and beta zeolites. TG-DTA and XRD characterization data indicated that: (i) Zr does not modify the crystalline structure of the parent zeolites, (ii) W develops a new crystalline phase, and (iii) V causes the breakdown of the zeolite structure during the aging step. The CO2 and N2 adsorption data revealed that the substituted zeolites present a narrower microporosity than pristine zeolites. As a consequence of all these modifications, the modified zeolites feature different adsorption capacity and kinetics of HCs, so, different hydrocarbon trapping ability than pristine zeolites. However, a clear correlation is not observed between the changes in the porosity/acidity of zeolites and the adsorption capacity and kinetics, which depends on: (i) the zeolite (ZSM-5 or BEA), (ii) the hydrocarbon (toluene or propene), and (iii) the cation to be inserted (Zr, W, or V).
