The p-NiO/n-α-Fe₂O₃ hetrostructures have been synthesized following three sequential steps. First, electrochemically NiO thin films are synthesized on FTO substrate, FeS₂ thin films are then electrodeposited onto NiO surface (FTO/NiO/FeS₂). On air annealing FTO/NiO/FeS₂ at 600 °C results NiO/Fe₂O₃, a completely different heterostructure. Electrochemical study shows that the sensor (NiO/Fe₂O₃) has sensitivity 1437 μA mM⁻¹ with detection limit 1.03 μM for glucose. The electrode is successfully applied to assay glucose concentration in human blood. The same electrode also exhibits prominent electrocatalytic activity to oxidise methanol in alkaline medium. The coupled semiconductor (NiO/Fe₂O₃) shows enhanced efficiency towards the photodecomposition of phenol and commercial dyes e.g., Congo red (CR), Rhodamine B (RhB). Again photo reduction ability of Cr(VI) is confirmed by the heterostructure which registers a remarkable reduction of toxic Cr(VI) to non toxic Cr(III). The present material can be used as a single platform to clean up the various environmental issues.

该p的NiO /正的α-Fe ₂ ö ₃ hetrostructures已经合成以下三个顺序步骤。首先，在FTO基板上电化学合成NiO薄膜，然后将FeS ₂薄膜电沉积到NiO表面（FTO / NiO / FeS ₂）上。在600°C的空气中进行FTO / NiO / FeS ₂空气退火后，会得到完全不同的异质结构NiO / Fe ₂ O ₃。电化学研究表明，传感器（NiO / Fe ₂ O ₃）的灵敏度为1437μAmM ^-1葡萄糖的检出限为1.03μM。该电极已成功应用于测定人血中的葡萄糖浓度。同一电极在碱性介质中还具有突出的电催化氧化甲醇的活性。偶合的半导体（NiO / Fe ₂ O ₃）对苯酚和市售染料（例如刚果红（CR），若丹明B（RhB））的光分解显示出更高的效率。异质结构再次证明了Cr（VI）的光还原能力，该异质结构表明有毒Cr（VI）显着还原为无毒Cr（III）。本材料可以用作清理各种环境问题的单一平台。
