Abstract
Owing to its good redox properties, excellent electron–hole pair generation, wide band gap and outstanding chemical stability, SnO 2 has been considered as a promising bifunctional material for supercapacitors as well as photocatalysts, but its poor conductivity and low surface area limit the specific capacitance and catalytic efficiency.
