Abstract

AbstractRecently, the environmental contamination caused by toxic dyes has posed a severe threat to human health. Semiconductor‐based photocatalysis is gaining a lot of attention due to its potential applications in environmental remediation. Herein, photocatalytic reactive FeCoWO4/g‐C3N4 nanocomposites were prepared through a facile route hydrothermal process. The bare FeCoWO4, g‐C3N4 and FeCoWO4/g‐C3N4 nanocomposites possess specific features, including reactive surface sites, improved efficiency of charge transfer, and accelerated separation of photogenerated electron‐hole pairs. As a result, the photocatalytic activity towards methylene blue dye (MB) degradation activity of FeCoWO4/g‐C3N4 nanocomposites is significantly improved. Thus, photocatalysts exhibited the highest degradation activities and could remove 91.5 % of MB dye within 120 minutes of visible light irradiation. The enhanced photocatalytic activity with excellent recyclability shows potential for the practical application of FeCoWO4/g‐C3N4 nanocomposites for wastewater treatment.
