New article published in ChemSusChem on degradation of dye pollutants via Sb-SnO2 nanodesigned materials
Our research team has published an article in ChemSusChem on the promising use of stable and efficient SnO2 electrodes for degrading refractory organic pollutants in wastewater treatment. Our approach involved the preparation of Ti3+ self-doped urchin-like rutile TiO2 nanoclusters (TiO2-xNCs) on a Ti mesh substrate using hydrothermal and electroreduction methods, which served as an interlayer for the deposition of Sb-SnO2. Our TiO2-xNCs/Sb-SnO2 anode exhibited a high oxygen evolution potential and strong *OH generation ability, resulting in improved degradation performance for rhodamine B, methylene blue, alizarin yellow R, and methyl orange. Our unique rutile interlayer also extended the anode lifetime sixfold due to its good lattice match with SnO2 and three-dimensional concave-convex structure. Overall, our work highlights the importance of designing interlayer crystal forms and structures for achieving efficient and stable SnO2 electrodes in addressing dye wastewater problems. This work was done in collaboration with our colleagues from Chongqing University.
