Abstract AR
تمت في هذه الدراسة تحضير التركيب الغير متجانس cDs / Tio2 عن طريق التفاعل المباشر للمركب CDs مع مركب TiO2 التجاري بتراكيز مختلفة.
تم استخدام أشعة Uv.-visb للمركب و تبين أن المركب قادرا على امتصاص الجزء الأكبر من الأشعة المرئية خصوصا ما بين 600-800 نانوميتر و قد أكدت النتائج العملية صحة هذه الحقيقة باستخدام الإشعاع المرئي و قد تم استخدام مركب الصبغة Orange G كمركب ملوث للماء لهذا الغرض و قد تبين أن الفعالية الضوئية لهذا التركيب تعتمد كثيرا على المادة الملوثة باستخدام مصباح زئبقي متوسط الضغط بقدرة 125 واط.
و كذلك أجرت التجارب تحت ظروف التشعيع بمنطقة UV-visible ملاحظة ظاهرة الاتحاد بين الإلكترون–الثقوب التي تحصل تحت هذه الظروف.
Abstract EN
CdS/TiO2 hetrojunctions were prepared by direct mixture of both constituents and by precipitation of the sensitizer with commercial TiO2 at different concentrations.
UV.–Vis.
Spectroscopy analysis showed that the junction – based CdS are able to absorb a large part of visible light ( respectively up to 800 and 600 nm ).
This fact was confirmed by photocatalytic experiment performed under visible light .
A part of charge recombination that can take place when semiconductor is excited was observed when photo catalytic experiment was performed under uv-vis illumination .
Orange G was used as a pollutant compound .
photo activity of the junctions was found to be strongly dependent on the substrate .
By using medium pressure mercury lamp (MPML) in 125 watt .
Photocatalyst experiment was also done under uv-vis illumination to establish the behaviour of the junction in real solar irradiation conditions and to observe apart of election – hole recombiration that can take plae under this conditions
