Photocatalytic degradation of contaminants of emerging concern using a low-cost and efficient black bismuth titanate-based water treatment reactor

Antibacterial Mesoporous Silica Granules Containing a Stable N-Halamine Moiety

“…At present, the lack of clean drinking water has become a serious challenge for many countries in the world . In the field of water purification, microbial contamination remains one of the most serious problems. , Commonly used water disinfection methods in the past few decades include free halogens, ozone, chloramine, and ultraviolet light. , However, these disinfection methods have some disadvantages. Free chlorine, ozone, and chloramine are strong oxidants, which may react with organic impurities in water to form undesirable byproducts during disinfection of drinking water. , Ultraviolet light does not have long-lasting sterilization ability and may lead to secondary microbial contamination of disinfected water …”

Fabrication of Bi2O3/Bismuth Titanates Modified with Metal–Organic Framework-In2S3/CdIn2S4 Materials for Electrocatalytic H2 Production and Its Photoactivity

“…Even pristine or unmodified bismuth oxides have good catalytic properties. Bismuth-based nanocomposites have incredible applications in wastewater treatment and electrochemical and energy production. − There are many bismuth-based composites available in the literature; out of the reported developed materials, the bismuth titanates have been shown as efficient base materials for energy and environmental applications. Ning Zhang reported that the photocatalytic activity of Bi 4 Ti 3 O 12 increased when modified with CuS.…”
