In this study, Carbon nano particles (C NPs) from neem leaves were synthesized for adsorption and photo catalytic degradation of Auramine–O (Au–O) dye used in paper industries. The synthesized C NPs were characterized by powder X-ray diffraction and scanning electron microscopy. Dye adsorption and photo catalytic properties of C NPs were examined by studying the decolorization of dye Au–O at 5 minutes time interval using a UV-Visible spectrophotometer. The results show that C NPs acts as a better adsorbent even with shorter time and lower concentration than as photocatalysts.

Синтезированы углеродные наночастицы (УНЧ) из листьев нима для адсорбции и фотокаталитического разложения красителя аурамин-О (Au-O), используемого в бумажной промышленности. Синтезированные НЧ С охарактеризованы методами порошковой рентгенографии и сканирующей электронной микроскопии. Адсорбцию красителя и фотокаталитические свойства НЧ C исследовали путем изучения обесцвечивания красителя Au–O с интервалом 5 минут с использованием спектрофотометра УФ-видимого диапазона. Результаты показывают, что НЧ C действуют как лучший адсорбент даже при более коротком времени и более низкой концентрации, чем фотокатализаторы.
