Visible Light Photoactivity of g-CN/MoS Nanocomposites for Water Remediation of Hexavalent Chromium.

Water pollution has becoming an increasingly serious issue, and it has attracted a significant amount of attention from scholars. Here, in order remove heavy metal hexavalent chromium (Cr (VI)) from wastewater, graphitic carbon nitride (g-CN) was modified with molybdenum disulfide (MoS) at different mass ratios via an ultrasonic method to synthesize g-CN/MoS (CNM) nanocomposites as photocatalysts. The nanocomposites displayed efficient photocatalytic removal of toxic hexavalent chromium (Cr (VI)) from water under UV, solar, and visible light irradiation.

Recent Progress in Photocatalytic Degradation of Water Pollution by Bismuth Tungstate.

Photocatalysis has emerged as a highly promising, green, and efficient technology for degrading pollutants in wastewater. Among the various photocatalysts, Bismuth tungstate (BiWO) has gained significant attention in the research community due to its potential in environmental remediation and photocatalytic energy conversion. However, the limited light absorption ability and rapid recombination of photogenerated carriers hinder the further improvement of BiWO's photocatalytic performance.
