文摘

The synthesis and characterization of SnO<sub>2sub> nanomaterials have been extensively studied as photoelectrodes for the potential applications in optoelectronic devices. In this work, SnO<sub>2sub> nanorods arrays have been synthesized by hydrothermal method on the nanoporous surface of the anodized stainless steel. The prepared SnO<sub>2sub> nanorods of 1.3–1.4 µm in length and 250–350 nm in width, were uniformly distributed on the anodized stainless steel. This one-dimensional SnO<sub>2sub> nanostructure directly fabricated on the substrate provides an electron transfer pathway and a Schottky-type contact, resulting in improved photocatalytic and photoelectrochemical performance. The SnO<sub>2sub> nanorods arrays exhibit fast response towards H<sub>2sub>O<sub>2sub> determination, producing a linear range from 100 to 3000 μM with a correlation coefficient of 0.984 and a sensitivity of 0.66 μA cm−2 mM−1. The results indicate the potential applications of SnO<sub>2sub> nanorods arrays as the non-enzymatic H<sub>2sub>O<sub>2sub> sensor.
