Sonodynamic therapy (SDT) has emerged as a highly effective modality for the treatment of malignant tumors owing to its powerful penetration ability, noninvasiveness, site-confined irradiation, and excellent therapeutic efficacy. However, traditional SDT, which relies on oxygen availability, often fails generate satisfactory level reactive species because widespread issue hypoxia in tumor microenvironment solid tumors. To address this challenge, various approaches are developed alleviate improve efficiency SDT. These strategies aim either increase supply or prevent exacerbation, thereby enhancing effectiveness In view this, current review provides an overview these their underlying principles, focusing circulation from consumption external supply. The detailed research examples conducted using combination with SDT also discussed. Additionally, highlights future prospects challenges hypoxia-alleviated along key considerations clinical applications. include development efficient delivery systems, accurate methods detection, exploration therapies optimize outcomes.

Altering the surface stoichiometry of semiconductor electrodes is known to affect photoelectrochemical (PEC) response. To date, several reports have hinted at influence Bi:V ratio on solar water oxidation performance BiVO4 photoanodes, but only a handful strategies been reported afford tuning such stoichiometry, while comprehensive understanding an atomic level role termination remains elusive. Herein, we report new methodology that modulates and maximizes PEC toward oxygen evolution reaction (OER). The presence ammonium metavanadate drastically reduces recombination improving charge separation. Detailed characterization revealed this treatment filled native vanadium vacancies, which usually act as centers, inducing significant increase in density reinforced built-in electric field drives Interestingly, coating with NiFeOx improves, especially, separation V-modified BiVO4. Results suggest altered energetics BiVO4, leading improved band alignment across interface. Overall, these results provide platform modulate thin films shedding light mechanisms by governs

Abstract Oxygen vacancies in oxygen evolution cocatalysts (OECs) can significantly improve the photoelectrochemical (PEC) water splitting performance of photoanodes. However, OECs with abundant have a poor stability when exposing to highly-oxidizing photogenerated holes. Herein, we partly fill MnCo 2 O x OEC N atoms by combined electrodeposition and sol-gel method, which dramatically improves both photocurrent density BiVO 4 photoanode. The optimized filled vacancy-rich /BiVO photoanode (3 at.% N) exhibits an outstanding 6.5 mA·cm −2 at 1.23 V RHE under AM 1.5 G illumination (100 mW·cm ), excellent over 150 h. Systematic characterizations theoretical calculations demonstrate that stabilize defect structure modulate surface electron distribution, enhances further increases density. Meanwhile, other heteroatoms such as carbon, phosphorus, sulfur are confirmed similar effects on improving PEC

Nanostructured bismuth vanadate (BiVO4) is at the forefront of emerging photoanodes in photoelectrochemical tandem devices for solar water splitting owing to suitable band edge position and efficient charge separation capability. However, (photo)chemical corrosion involving V5+ dissolution limits long-term stability BiVO4. Herein, guided by DFT calculations, we introduce an ALD-derived NiOx catalyst layer on BiVO4 stabilize surface Bi–O bonds, facilitate hole extraction, thus suppress dissolution. At same time, ALD could efficiently recombination accelerate OER kinetics, boosting half-cell applied bias photon-to-current efficiency 2.05%, as well a fill factor 47.1%. By adding trace NaVO3 electrolyte, NiOx/BiVO4 photoanode with illumination area 10.5 cm2 shows record operational more than 2100 h.
