Abstract

The composition of the plant material and the polarity of the solvents are factors that affect the extraction efficiency. Natural pigments as photosensitizers offer benefits of natural abundance, environmental friendliness, simplicity of preparation and low cost. This research work focused on the Comparative Study of the Photocatalytic Activities of Canarium Schweinfuthii and Justicia Carnea as Photosensitizers using Different Extraction Solvents. Dyes were extracted using cold extraction technique. Using surface profilenometry with a VeecoDektak 150 profiler machine; the result showed that all the samples are thin films. Using SprectrumLab 752S UV-VIS Spectrophotometer for the characterizations, the results of the absorbance spectra of justicia carnea leaf using CH3OH as extraction solvent showed the highest absorbance range of (0.738a.u. – 1.602a.u.) within the visible region, although all the samples irrespective of the extraction solvents showed high absorbance values within 400nm-700nm. For results of transmittance, the average transmittance values for all the samples within the visible region deceased drastically. For refractive index, the results showed high refractive index range of (2.00a.u – 19.121 a.u)and justicia carnea leaf extract using CH3OH as extraction solvent having the highest refractive index range of (2.589a.u – 18.587a.u). The Extinction Coefficient increases within the visible region for all the samples. Film of justicia carnea with CH3OH showed Direct band gap of 2.00eV while with C2H6O showed 2.20eV. Films of canarium schweinfurthii showed direct band gap of 2.10eV with CH3OH, while C2H6O showed 2.40eV. The Indirect band gap for films of justicia carnea showed 1.60eV and 1.80eV for CH3OH and C2H6O respectively. While Indirect band gap for films of canarium schweinfurthii showed 1.80eV and 2.00eV for CH3OH and C2H6O respectively. Hence the leaf extracts, irrespective of its extraction solvents are good
