Correction to: Nano-Micro Lett. (2019) 11:12 https://doi.org/10.1007/s4082 0-019-0242-8

In the original publication, Figure S4 is an ancillary image to compare the specific surface areas of TiO2/Ni3S2and Ni3S2samples and it was incorrectly published. To better serve our readers, the correct figure is provided in this correction. The BET values are correct and unaffected. The corresponding figure caption, data analysis and conclusions are not affected and thus not to be changed. The authors would like to apologize for any inconvenience caused.
