摘　　要：利用简易的水热合成技术在不锈钢表面制备TiO_(2)纳米棒结构以获得自清洁抗菌不锈钢。通过改变水热时间调控不锈钢表面TiO_(2)纳米棒结构的直径和薄膜厚度,研究水热时间对不锈钢光电化学性能、光电催化降解性能的影响。结果表明,在水热1 h所制备的不锈钢样品的光电流密度最大,达到了34μA/cm^(2),光电催化降解率达到了99%,抗菌率为99%以上。研究表明TiO_(2)纳米棒结构在不锈钢表面的成功负载明显提高了不锈钢的自清洁抗菌性能。A simple hydrothermal synthesis technique was used to prepare TiO_(2) nanorods on the surface of stainless steel to obtain self-cleaning antibacterial stainless steel.The diameter and film thickness of TiO_(2) nanorod structure on stainless steel surface were adjusted by changing the hydrothermal time,and the effect of hydrothermal time on the photoelectrochemical properties and photoelectrocatalytic degradation properties of stainless steel was studied.The results showed that the highest photocurrent density of the stainless steel samples prepared by hydrothermal treatment for 1 h was reaching 34μA/cm^(2),while the photocatalytic degradation rate reached 99%,and the antibacterial rate was up to 99%.The results indicated that the successful loading of TiO_(2) nanorods on the surface of stainless steel significantly improved the self-cleaning and antibacterial properties of stainless steel.
