1. Deposition of nanocrystalline layers



Substrate preparation

  • Substrate preparation

  • Hot-Filament CVD-method

  • Operating parameters (gas Mixture 1% CH4 + 99% H2)





Immobilization of

  • Immobilization of

  • Mn-PhC

  • Preparation of the solution

  • Treatment of the NCD-layers (about 12 hours)





Cyclic curves of unmodified NCD-sample without phthalocyanine

  • Cyclic curves of unmodified NCD-sample without phthalocyanine

  • Under  illumination the electrode surface is stable and changes are not observed



Cyclic curves of NCD-sample with phthalocyanine under and without illumination

  • Cyclic curves of NCD-sample with phthalocyanine under and without illumination

  • There is a difference between the measurements obtained in dark and under illumination

  • The voltammetric curves clearly indicate both oxidation and reduction processes answerable for the detected photocurrent.
