Nanoporous Silicon with Graphene-like Coating for Pseudocapacitor Application.

This paper presents the results of studies of the nanoporous silicon structure, both with different pore depths (up to 180 μm) and with layers in which a graphene-like coating was synthesized on the inner surface of the pores. The nanoporous layers were characterized by SEM as well as IR and Raman spectroscopy. Cyclic voltammetry and galvanostatic charge-discharge data in 3 M HSO are presented as well as the results of the cyclic stability of these characteristics for the nanoporous structure.
