Combining montmorillonite mineral and SnO2/TiO2 photocatalysts for high-performance and cost-effective nitrogen oxide decomposition

Development of cost-effective photocatalysts for environmental pollution treatment is trending in materials science research. In this study, montmorillonite (MMT) was combined with SnO2/TNTs photocatalysts for the efficient NO gas treatment. The MMT enhanced the photocatalytic efficiency for NO gas treatment. Notably, the 10% MMT/SnO2/TNTs photocatalyst exhibited a significant green product yield of 54.3% and achieved 10-4% of quantum efficiency. Moreover, the 10% MMT/SnO2/TNTs photocatalyst has high stability with less change of the NO photocatalytic degradation for five cycles. The 10% MMT/SnO2/TNTs photocatalyst also expressed oxidation and reduction reactions in the NO photocatalytic reactions. The incorporation of MMT has led to a noteworthy reduction in the production cost of the catalyst, making it a cost-effective solution. These findings emphasize the significance of integrating MMT to attain improved photocatalytic performance and cost efficiency in practical applications.
