    The effects of the C 18 TMS percentage on the dispersity, mesoporous structure and particle size of HMSNs have been discussed in detail based on elaborate structure characterization. In addition, the volume of the core-etching agent and etching time have been adjusted carefully to further modulate the mesoporous structure of HMSNs.

    The adsorptive properties of platinized electrodes, as indicated by cyclic voltammetry, depended on the potential of platinum electrodeposition. Electrodes deposited above V v. reversible hydrogen electrode were similar to smooth platinum, while those deposited at negative potentials showed anomalous behaviour, particularly with regard to hydrogen sorption.
