A ternary Pt/Au/TiO 2 nanoparticle (NP) decorated plasmonic wood carbon has been successfully fabricated by a simple two‐step calcination method. The as‐prepared Pt/Au/TiO 2 NP‐decorated wood carbon showed an interfacial solar steam generation efficiency up to 90.4 %. Furthermore, the floating system exhibits an excellent photodegradation of tetracycline (TC; 40 mg L −1 ). Up to 94 % degradation was achieved after 80 min of continuous light irradiation ( λ >420 nm) with the assistance of solar steam process. The photocatalysis is promoted by the introduction of Pt/Au nanocomponents, which suppress the recombination of electron–hole pairs generated on TiO 2 and facilitate electron transfer. High‐performance liquid chromatography mass spectrometry was employed to identify the reaction products of the photocatalytic system and a mechanistic insight was also provided. The as‐prepared three‐dimensional plasmonic wood carbon has a high photocatalytic performance. Such wood carbon‐based system is recyclable and scalable for practical and versatile solar‐driven clean water generation.
