Abstract Owing to the high depth of tissue penetration, non‐invasiveness, and controllability, ultrasound (US)‐mediated sonodynamic therapy (SDT) has shown broad application prospects for tumor treatment. However, electron‐hole separation inefficiency sonosensitizers hypoxia remain two major challenges limiting effect SDT. Here, ultrafine photoetched bismuth vanadate (BiVO 4 ) nanorods modified with DSPE‐PEG 2000 (PEBVO@PEG NRs) were fabricated achieve in situ self‐supply oxygen (O 2 reactive species (ROS) hypoxic therapy. The photoetching approach could enhance charge by inducing enriched vacancies on surface BiVO , thereby improving generation efficiency ROS O . PEBVO@PEG overcome main obstacles traditional SDT process show promising therapeutic effects, thus providing new strategies performance sonosensitizer elimination.

Abstract Photoelectrochemical (PEC) cells are regarded as a promising approach to convert sunlight chemical fuels, whereas the serious photo‐induced charge recombination of semiconductor photoelectrode hinders its solar conversion efficiency. Over past few decades, designing and constructing heterojunction photoelectrodes via thermodynamically favorable transfer have been proven be effective in boosting separation. However, conventional construction strategy generally introduces incompatible, nonconformal, or defective interfaces, leaving considerable room improve efficiency photoelectrodes. To compensate for unsatisfied efficiency, some novel strategies, such grain boundary engineering, band gap field‐effected etc., adopted provide additional driving force, which significantly improves In this review, these strategies discussed beyond construction, prospects development applications photoanodes also proposed.
