Potassium hexatitanate has been barely studied as a photocatalytic material for the hydrogen production from water splitting. The aim is to synthesize and characterize K₂Ti₆O₁₃ fibers in order to evaluate their photocatalytic activity. Materials were characterized by XRD, BET, UV–Vis and SEM. Fibers were produced with sizes varying from 12 to 35 μm in length and 260–530 nm in diameter, as well as with a specific surface area of 4.1 m²/g and 2.3 m²/g for a heat treatment at 900 °C (C21) and 1000 °C (C22), respectively. Band gap energies for these titanates fall within the visible spectrum 3.23 eV (C21) and 3.28 eV (C22), respectively. Maximum hydrogen production was achieved by (C21) with 2387 μmolH₂/gcat, while the lowest production was observed for sample (C22) with 1538 μmolH₂/gcat at 8 h of irradiation. Crystals of K₂Ti₆O₁₃ exhibited high photocatalytic activity and they can be considered as potential photocatalysts for H₂ production.

很少有人研究六钛酸钾作为光分解水分解氢产生物质的光催化材料。目的是合成和表征K ₂ Ti ₆ O ₁₃纤维，以评估其光催化活性。材料通过XRD，BET，UV-Vis和SEM表征。生产的纤维长度在12至35μm之间，直径在260-530 nm之间，比表面积分别为4.1 m ² / g和2.3 m ² / g，可在900°C下进行热处理（ C21）和1000°C（C22）。这些钛酸盐的带隙能量分别在可见光谱3.23 eV（C21）和3.28 eV（C22）范围内。（C21）达到2387μmolH的最大产氢量₂ / g催化剂，而观察到对样品（C22）与1538μmolH最低的生产₂在照射8小时/ g催化剂。K ₂ Ti ₆ O ₁₃晶体表现出高的光催化活性，可以认为它们是生产H _2的潜在光催化剂。
