Photocatalytic Hproduction has emerged as one of the most clean and promising renewable energy sources. In spite of the efforts to obtain efficient photocatalysts able to produce Hfrom Sun light and water, there is still the need to prepare cheaper and environmental friendlier photocatalysts. Phosphatebased materials could be good candidates to fulfill these requirements. In this manuscript we have prepared a set of mixed Ti/Tivalence, open-framework titanium phosphates（of-TiPO） and mixed titanium oxide/phosphate derivatives（cr-Ti P）, correlating their structure and composition with the photocatalytic activity for Hproduction. We determined that mixed titanium oxide/phosphate crystalline phases produced enhanced Hevolution under Sun simulated light irradiation than mixed Ti/Tivalence, open-framework titanium phosphates and titanium oxide phases.

Recent reports suggest that aging is not solely a physiological process in living beings;instead, it should be considered a pathological process or disease(Amorim et al., 2022). Consequently, this process involves a wide range of factors, spanning from genetic to environmental factors, and even includes the gut microbiome(GM)(Mayer et al., 2022). All these processes coincide at some point in the inflammatory process, oxidative stress, and apoptosis, at different degrees in various organs and systems that constitute a living organism(Mayer et al., 2022;AguilarHernández et al., 2023).
