| Popis: | The synthesis and characterization of SnO2 nanomaterials have been extensively studied as photoelectrodes for the potential applications in optoelectronic devices. In this work, SnO2 nanorods arrays have been synthesized by hydrothermal method on the nanoporous surface of the anodized stainless steel. The prepared SnO2 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 SnO2 nanostructure directly fabricated on the substrate provides an electron transfer pathway and a Schottky-type contact, resulting in improved photocatalytic and photoelectrochemical performance. The SnO2 nanorods arrays exhibit fast response towards H2O2 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 SnO2 nanorods arrays as the non-enzymatic H2O2 sensor. |
