Using XRD, CHN, TG, 13C NMR, BET, SEM, and GC-MS, the solidity of platinized n-butylamineintercalated layered titanate H2La2Ti3O10 was investigated during photocatalytic hydrogen production from fluid methanol under UV light. After three hours of reaction, the photocatalyst’s particle morphology and specific surface area remained the same, and n-butylamine completely left the interlayer space to become n-butyraldehyde. Carbon is present in at least two distinct oxidation states in the final solid phase because the intermediate products of methanol oxidation are bound to the perovskite matrix. An approximate linear equation of 29.2 pH holds for the apparent quantum efficiency of producing hydrogen at a concentration of one mole between 220 and 340 nm. In contrast to the parent H2La2Ti3O10 or TiO2, this photocatalyst’s activity is stable over time and strongly influenced by the pH of the medium. methanol concentration. In the acidic medium, the investigated photocatalyst outperforms the platinized H2La2Ti3O10 by more than one order of magnitude. At 10 mol. %, The highest quantum efficiency of hydrogen production was achieved by altering the methanol grouping. to be present there.
