Hydrothermal synthesis followed by a calcination step was used to prepare porous Zn2SnO4 powders using carbon black as a pore-forming agent. The porous Zn2SnO4 was used as a photocatalyst to degrade the Rhodamine B dye from aqueous solution under UV artificial light. X-ray diffraction, N2adsorption-desorption isotherms, and UV-Vis diffuse reflectance were used to characterize the material. The addition of pore-forming agent (carbon black) did not change the crystalline structure of Zn2SnO4 phase. In addition, increasing the surface area and porosity as well as decreasing the band-gap energy was observed. The combination of these characteristics favored the photodegradation of Rhodamine B, reaching 96% of dye degradation at 15 min of reaction time. In addition, the photocatalyst was active after six cycles of reuse. Therefore, the produced material in this work showed to be a potential photocatalyst to remove Rhodamine B dye from aqueous solution.
