- Full‐Spectrum Solar‐Driven Photothermal Strategy Based on Oxygen‐Vacancy‐Engineered NiOOH@H‐TiO 2 for High‐Efficiency Sewage Remediation Jiale Zhu Liangdong Hu Lian‐Hua Xu Longfei Hong Jiajun Yu Zhuzhu Zhang Huiyan Zhang ChemSusChem Harnessing solar energy for pollutant removal remains constrained by limited light‐harvesting efficiency and insufficient interfacial compatibility between catalysts and organic contaminants. Here, we report a full‐spectrum photothermal catalytic platform based on commercial TiO 2 engineered with surface oxygen vacancies. The introduction of oxygen‐vacancy sites establishes a dynamic adsorption environment capable of binding key functional groups of organic pollutants while simultaneously converting TiO 2 into a broadband‐absorbing black derivative that exhibits pronounced photothermal response under near‐infrared irradiation. Incorporation of NiOOH further enhances charge generation and promotes the formation of reactive oxygen species (•OH and •O 2 − ), thereby accelerating photothermal oxidation pathways. The NiOOH@H‐TiO 2 enables rapid degradation of Rhodamine B (20 ppm), achieving >99% removal within 5 min, and maintains >98% efficiency over five consecutive cycles with negligible activity loss (<2%). These results demonstrate a generalizable approach for constructing full‐spectrum photothermal catalysts and offer new insights into solar‐driven water purification. 10.1002/cssc.70752 http://onlinelibrary.wiley.com/termsAndConditions#vor
