Abstract

Correction for ‘Au@PdOx with a PdOx-rich shell and Au-rich core embedded in Co3O4 nanorods for catalytic combustion of methane’ by Yan Zhu et al., Nanoscale, 2017, 9, 2123–2128.

The authors regret that the units provided for the reaction rate and TOF of the catalysts were misdescribed due to the ‘%’ of methane conversion being omitted in the calculations. The units provided for the reaction rate and TOF of the catalysts in Fig. 2B, Table 1, Tables S1 and S2, and Fig. S8B therefore all need to be multiplied by 10−2. As an example, a revised version of Fig. 2B is provided below, with the corrected units highlighted in red.

Fig. 2 (A) Methane conversion versus temperatures and (B) ln(rate) − 1/T plots for CH4 combustion over (a) Au@PdOx (1[thin space (1/6-em)]:[thin space (1/6-em)]5)/Co3O4, (b) AuPd (1[thin space (1/6-em)]:[thin space (1/6-em)]5)/Co3O4, (c) Pd/Co3O4, (d) Au/Co3O4 and (e) Co3O4 respectively.

We would like to state that the changes do not affect the overall conclusions of the original manuscript, as all of the units for the reaction rates and TOFs in the manuscript were corrected at the same time. Moreover, we compared the catalytic performances of the catalysts reported in our work with those reported in the literature (Table C1), and we found that the activities of our catalysts are better than or comparable with those of the reported catalysts.

Table 1 Catalytic performances of catalysts developed for lean methane oxidation reported in our work and in the literature. The data given in the table correspond to the Au and Pd weight loading of the samples, reaction conditions, reaction rate (r) (calculated using the weight of the catalysts) at 250 °C, and T90.
