Content of review 1, reviewed on July 23, 2025
The manuscript reports the double carbon coating on Si nanoparticles with rGO and carbon. The performance of Si based composite materials is good, and the authors analyzed properly. However, the similar works have been performed, and I cannot see the critical difference with the references. Therefore, this manuscript need to address the clear idea in this manuscript for publication in Dalton Transactions. The other comments are as follows.
(1) In Scheme 1, there is no image of petroleum. It could be removed.
(2) What is the composition of PNC/C? In XPS analysis, the nitrogen configuration should be performed.
(3) The surface area of PNC/C is very important for composite with Si. Please give the PNC/C surface area alone.
(4) In figure 3d, there are strange points. After restoring to 0.1C rate(60 cycle), the capacity of Si@PNC/C enhanced and reduced. Why? And the capacity of Si@rGO@PNC/C is small and enhanced. Why?
(5) The capacitive and diffusion contributions for other samples should be suggested.
(6) In Figure 5, the thickness of each electrode is quite different. Why? The amount of carbon is similar, then the thickness could be similar.
