Ultrathin bismuth oxyhalides solid solution nanosheets with oxygen vacancies for enhanced selective photocatalytic NO removal process

In Situ Construction of BiO(ClBr)(1–x)/2Ix–n Solid Solution with Appropriate Surface Iodine Vacancies for Synergistically Boosting Visible-Light Photo-Oxidation Capability

“…In addition, the construction of solid solutions contributes to the tuning of the band gap and crystal structure of materials, achieving a balance between light response range and redox capacity. − Since BiOCl, BiOBr, and BiOI all share the same atomic configuration, the halogen atoms can be readily substituted for each other to form solid solutions. In view of this, Lu et al synthesized tunable-band-gap BiOBr x I 1– x solid solutions demonstrating efficient degradation activity under visible light by the ultrasonic-assisted hydrolysis method .…”
