Metal Oxide Composites as Oxygen Carriers for the Application of Chemical Looping Technologies

Dear Colleagues,

Chemical looping technologies have emerged as attractive processes for the applications of clean energy and syngas production. Thanks to its dual-fluidised bed reactor system, air never mixes with the fuel, which inherently separates CO₂ from the other flue gas components. Metal oxides, such as Cu-, Co-, Mn-, Ni-, Fe-based and their composites, transfer the oxygen between these two interconnected reactors as oxygen carriers and play a crucial role in the commercialisation of the chemical looping technologies. Successful applications of these technologies will require an extensive understanding of metal oxide composites, such as large-scale synthesis procedures, reactivity, surface interactions with additives, phase and structural changes, interaction with fuels, and long-term stability and reliability. Additionally, both modelling and experimental studies on the application of composite metal oxides could be an effective way to identify the candidates for chemical looping technologies. We invite researchers to contribute to the Special Issue on “Metal Oxide Composites as Oxygen Carriers for the Application of Chemical Looping Technologies”, which is intended to serve as a forum covering broad aspects of the science, technology, and applications of metal oxide composites as oxygen carriers in chemical looping technologies. 

The potential topics include, but are not limited to:

• Synthesis of novel metal oxide composites as oxygen carriers;
• Advanced material characterisation techniques on oxygen carriers;
• Phase and structural changes of oxygen carriers in chemical looping applications;
• Kinetics of oxygen carriers under chemical looping applications;
• Computational modelling of surface interactions of oxygen carriers with additives;
• Quantitative structure property relationships and predictions of new oxygen carriers.

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 250 words) can be sent to the Editorial Office for assessment.

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. Crystals 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 2100 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.
