We have become aware that figures and experimental data in the published article [1] are identical to a previously published paper by the same authors [2]. While the authors claim that the work was sufficiently different to that of the previously published paper, our Editorial Board did not agree and we have therefore decided to retract the paper. Despite low levels of textual overlap, the work is essentially the same as what was previously reported.
MDPI is a member of the Committee on Publication Ethics and takes the responsibility to enforce strict ethical policies and standards very seriously. To ensure the addition of only high quality scientific works to the field of scholarly publication, [1] is retracted and shall be marked accordingly. We apologize to the readership of Catalysts for any inconvenience caused. We note that two other papers by the same author are being retracted for similar reasons [3,4].
