Effect of fuel dosage in self-propagation combustion: Evolution of BiOCl to BiOCl/Bi24O31Cl10 heterojunction enriched with oxygen vacancies

BiOCl/Bi 24 O 31 Cl 10 heterojunction: BiOCl and Bi 24 O 31 Cl 10 contact to form a type-Z heterojunction. The band bending facilitates the transfer and recombination of charge carriers of low redox potential, leading to improved degradation efficiency.
