All articles published in Catalysts (ISSN 2073-4344) are published in full open access. In order to provide free access to readers, and to cover the costs of peer review, copyediting, typesetting, long-term archiving, and journal management, an article processing charge (APC) of 1600 CHF (Swiss Francs) applies to papers accepted after peer review. In addition to Swiss Francs (CHF), we also accept payment in Euros (EUR), US Dollars (USD) or British Pound Sterling (GBP).
Reviewers who provide timely and substantial comments will receive a discount voucher code entitling them to a reduction in the article processing charge (APC) of a future submission to an MDPI journal. Vouchers are valid for two years and multiple vouchers can be redeemed against the same article. See http://blog.mdpi.com/2016/10/13/reviewing-for-mdpi-just-became-more-rewarding/ for details.
