Fabrication of Interface Engineered S-Scheme Heterojunction Nanocatalyst for Ultrasound-Triggered Sustainable Cancer Therapy.

ABSTRACT: In order to establish a set of perfect heterojunction designs and characterization schemes, step-scheme (S-scheme) BiOBr@Bi₂S₃ nanoheterojunctions that enable the charge separation and expand the scope of catalytic reactions, aiming to promote the development and improvement of heterojunction engineering is developed. In this kind of heterojunction system, the Fermi levels mediate the formation of the internal electric field at the interface and guide the recombination of the weak redox carriers, while the strong redox carriers are retained. Thus, these high-energy electrons and holes are able to catalyze a variety of substrates in the tumor microenvironment, such as the reduction of oxygen and carbon dioxide to superoxide radicals and carbon monoxide (CO), and the ox
