Visible-light-responsive K-doped g-C3N4/BiOBr hybrid photocatalyst with highly efficient degradation of Rhodamine B and tetracycline

Superhydrophobic Self-Supporting BiOBr Aerogel for Wastewater Purification

“…Bismuth halides BiOX (bismuth oxyiodide, bismuth oxychloride, bismuth oxybromide, etc.) have been extensively applied to the degradation of organic contaminants because of their desired optimal optical and photocatalytic performances. − Among the numerous Bi-based semiconductor photocatalysts, BiOBr has been widely used in the field of water-soluble degradation, depending on possessing appropriate band gap positions, remarkable electrical properties, and a particular lamellar structure. − Even more importantly, achieving the combination of the functions of superhydrophobic and photocatalytic properties will become a boon to the whole ecological environment. To introduce the catalysts into the 3D materials, Yang et al fabricated a composite aerogel by the hydrothermal synthesis of BiVO 4 quantum tubes (BVO QTs as a light absorber) and reduced graphene oxide (as a structural supporter).…”

Objective Findings on the K-Doped g-C3N4 Photocatalysts: The Presence and Influence of Organic Byproducts on K-Doped g-C3N4 Photocatalysis

“…We tried to identify the organic byproducts in the resultant K-doped g -C 3 N 4 through MS detection, but the MS results showed that the byproducts are a complex mixture (Figure S4). K-doped g -C 3 N 4 is usually used as a photocatalyst for environmental purification applications, − and the influence of organic byproducts on the reaction of the K-doped g -C 3 N 4 photocatalyst is worthy of estimation. Figure a–c shows the dissolution of organic byproducts from K-doped g -C 3 N 4 samples into water at room temperature with stirring under dark conditions and under illumination, respectively.…”

Novel BiOBr by compositing low-cost biochar for efficient ciprofloxacin removal: the synergy of adsorption and photocatalysis on the degradation kinetics and mechanism insight

“…Among these antibiotics ciprooxacin (CIP) is a representative uoroquinolone antibiotic with antibacterial effects. 1,2 Most studies have reported that animals rarely absorb CIP, and most of it is passively excreted from the body through metabolism and then enter the biosphere cycle aer sewage treatment. 3,4 The accumulation of CIP causes a potential damage to the ecological environment and human health, producing drug-resistant pathogens.…”
