dc.description.resumoPhotocatalysts were synthesized from anodic paste of alkaline batteries waste. After washing step, the material was calcined at different temperatures such as 600 °C (AB-600), 700 °C (AB-700) and 800 °C (AB-800). However, only the temperature of 600 °C produced a Zn/ZnO heterostructure. The Zn/ZnO heterostructure consisted by hexagonal wurtzite structure and metallic Zn confirmed by X-Ray Diffraction. The material showed a nanorod format with quasi-spherical Zn nanoparticles presence. AB-600, AB-700 and AB-800 showed high thermal stability in the range of 25–900 °C and band gap energy values were between 3.14 and 3.19 eV. The materials were applied in the photodegradation of the Direct Red 80 dye (DR80) and the AB-600 showed the best efficiency. The DR80 removal by AB-600 occurs under UV and visible radiation that demonstrates the advantage of the material that can be activated by solar radiation. The mechanism evaluation DR80 degradation by AB-600 demonstrate that removal occurs by direct oxidation in photogenerated vacancies and indirectly by •OH radicals. Therefore, it can be concluded that it was synthesized a promising photocatalyst from waste batteries by a sustainable route, which can be used in the dye degradation.pt_BR
