Abstract EN
The adsorption of natural pigments onto TiO2 nanoparticles was investigated.
The pigments were extracted from the dark purple colored pulp of the berry-like capsule of Kuduk-kuduk (Melastoma malabathricum L.).
The Langmuir, Freundlich, Redlich-Peterson, and Sips isotherm models were used to analyze the equilibrium experimental data.
Data correlated well with the Sips isotherm model, where the heterogeneity factor ( n = 0.24 ) indicated heterogeneous adsorption characteristics, with a maximum adsorption capacity of 0.0130 mg/g.
The heterogeneous adsorption character was further supported by results obtained from zeta-potential measurements.
When a dye-sensitized solar cell (DSSC) was sensitized with the extracted pigment, the photo-energy conversion efficiency was measured to be 0.83%, thus proving the suitability of Kuduk-kuduk fruit pulp as a sensitizer in DSSCs.
