AbstractA well-defined porous carbon structure with tunable parameters provides a platform for a systematic study of transport and confinement effects on electrochemical conversion. Synthesized via silica template techniques, the hierarchical structure has a hollow core within a mesoporous shell (HCMS) with uniform pore size, shell thickness, hollow core diameter, as shown in Fig. 1. Previously, electrochemical capacitance was studied with a series with meso-shell thickness stepwise increased from 0, 25, 50 to 100 nm while keeping an identical 330 nm hollow core and mesopore of 3.9 nm.[1, 2] Electrochemical impedance spectra (EIS) results reveal the need to match the AC frequency with the characteristic time constant of a structure for optimum active and reactive power …
