Local Visible-Photocatalytic Production of Hydrogen and Warm Heat for Combination Treatment of Pressure Ulcer.

ABSTRACT: Pressure ulcer (PU) is hardly cured due to repeated pressures-induced serious ischemia-reperfusion injury (IRI), poor microcirculation, and chronical inflammation. Hydrogen molecule (H₂) is proved as an emerging anti-inflammatory and anti-IRI agent with high biological safety, while local warm heating is well identified and able to improve tissue microcirculation for promoting wound repair. This work proposes a new strategy of visible-photocatalytic hydrogen/warm heat production for combination treatment of PU, and develops palladium nanodots-deposited hydrogen-doped titanium dioxide nanorod (HTON-Pd) as a novel multifunctional photocatalyst, achieving controllable and sustainable visible-photocatalytic production of H₂ and heat. Daily administration of the HTON-Pd en
