Interface and Defect Engineering in 3D Co 3 O 4‐Ov /TiO 2 to Boost Simultaneous Removal of BPA and Cr(VI) upon Photoelectrocatalytic/Peroxymonosulfate (PEC/PMS) System (Adv. Funct. Mater. 3/2025)

Dual Heterojunctions In article number 2414350, Ya-nan Zhang and co-workers design an advanced Co3O4−Ov/TiO2 photoelectrode via a dual-modification strategy encompassing interface engineering and defect engineering. The photoelectrode is further combined with a synergetic photoelectrocatalytic/peroxymonosulfate system (Co3O4−Ov/TiO2-PEC/PMS system), leading to a highly efficient simultaneous removal of BPA and Cr(VI) within only 15 min with fast kinetics (0.21 min−1 for BPA, 0.29 min−1 for Cr(VI)).
