Weekly Report 3&4

In this week, I have learnt the articletitled “Direct instrumental identification of catalytically active surfacesites” published in Nature. The main point of author is that directly identifyand monitor active sites in operando conditions by the tunnelling current noiseof EC-STM or STM, which making it then possible to evaluate the relativecontribution to overall catalyst activity of different defects and activesites. In addition, the tunnelling current noise reflected the active sites isa function as time compared with those over non-active sites, and therefore thecurrent noise can record the changes of active sites in reaction conditions.It’s worth noting that the Faradaic current of hydrogen oxidation between tipand sample is influenced to the tunnelling current noise useful for us, whereasthe vibration is slightly. The details have been discussed in experimentalmethods.

That's not all.
