Special Issue Information
Dear Colleagues,
Noble metal nanoparticles such as Pt, Pd, Rh, Au, Ag, Ir, Ru, and Os supported on alumina, silica, zirconia, titania, zeolites, and structured mesoporous materials have found applications as heterogeneous catalysts in several industrial processes such as petroleum refinery, environmental catalysis, exhaust emission control of stationery and motor vehicles, water purification, and the synthesis of fine and specialty chemicals. Furthermore, noble metal-modified catalytic materials, due to their acid and corrosion resistance properties, can also be applied as sensors, biomedicine products, antimicrobial actions, electronics, hydrogenations, and dehydrogenation reactions.
Noble metal nanoparticles’ sizes, dispersions, oxidation states, acid sites, and meta-supporting interactions are highly influenced by the methods of catalyst preparation such as evaporation impregnation, co-precipitation, deposition precipitation, ion exchange, in situ synthesis, and chemical vapor deposition. The future challenges related to noble metal-modified catalytic materials include the development of cost effective, highly selective, and stable catalysts for applications in the production of bulk, fine, and specialty chemicals using environmentally friendly technologies. Taking into consideration sustainable development initiatives, it is of immense importance that noble metal-modified catalysts are applied in the rational utilization of limited natural resources.

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 2200 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.
