“…However, only few reports involved the direct growth of TiO 2 /MnO 2 nanocomposites on the FTO surface to construct binder‐free electrodes, not to mention the application in H 2 O 2 biosensors . Recently, Zhang and coworkers reported a TiO 2 @MnO 2 nanotube array produced by a pulsed electrodeposition technique onto a FTO substrate for the application in supercapacitors . Kim and coworkers reported the fabrication of hierarchically structured TiO 2 @MnO 2 nanowall arrays onto FTO through a hydrothermal process for use as an electrode for supercapacitors .…”

A novel nanocomposite electrode based on hierarchical 3D porous MnO2−TiO2 for the application in hydrogen peroxide (H2O2) sensors has been explored. This electrode was fabricated by growing TiO2 cross‐linked nanowires on a commercial fluorine tin oxide (FTO) glass via a hydrothermal process and subsequent deposition of 3D honeycomb‐like MnO2 nanowalls using an electrodeposition method (denoted as 3D MNS‐TNW@FTO). The obtained 3D MNS‐TNW@FTO electrode was characterized by scanning electron microscopy (SEM), Raman spectroscopy, X‐ray diffraction (XRD), and X‐ray photoelectron spectroscopy (XPS). Based on such a unique 3D porous framework and the existence of MnO2, the electrode demonstrates a good performance in the detection of H2O2, with two linear ranges from 9.8 to 125 μM and 125 μM–1.0 mM, a good selectivity of 8.02 μA mM−1 cm−2, and a low detection limit of 4.5 μM. In addition, the simplicity of the developed low‐cost fabrication process provides an efficient method for the mass production of electrocatalytical MnO2−TiO2 nanocomposites on commercial FTO glass for H2O2 sensing applications and can be adapted for other electrochemical sensors for various biochemical targets. It thus is beneficial for the practical usage in bioanalysis.

New composite based on polypyrrole (PPy) and bismuth oxide (α-Bi 2 O 3) was investigated as supercapacitor electrode. The α-Bi 2 O 3 was obtained by hydrothermal route at 500 o C for 2 h. Cyclic voltammetry was used to electropolymerize PPy on graphite electrode (GE) or on GE/α-Bi 2 O 3. The X-ray diffraction profile of Bi 2 O 3 revealed the α-Bi 2 O 3 monoclinic structure with space group P2 1 /c. The scanning and transmission electron microscopy images showed that PPy coated α-Bi 2 O 3. Raman spectra showed that PPy inhomogeneously coated α-Bi 2 O 3 , but it was still possible to obtain a α-Bi 2 O 3 @PPy core-shell hybrid composite with highly ordered α-Bi 2 O 3 with electronic interaction between the oxide and the polymer chain of the polymer. The GE/α-Bi 2 O 3 @PPy composite electrode (type I supercapacitor) displayed a predominantly capacitive profile with low impedance values and good electrochemical stability after 50 charge and discharge cycles. The specific capacitance of α-Bi 2 O 3 @PPy composite was found in the range of 634 to 301 F g-1 to gravimetric current of 3 and 10 A g-1 , respectively.

“…Several studies on MnO 2 itself, as a catalyst for OER of water, have been performed 16,17 .Nanoscale MnO 2 was prepared and incorporated into electrically conductive frameworks, which has been well proven to be an effective and promising strategy. Developing nanostructured current collectors with the high surface area and enhanced conductivity is also mandatory for supercapacitor materials [18][19][20] , however, more enhancement is required to achieve the remarkable photocatalytic properties of the MnO x /TiO 2 photoelectrodes 21 . There have been quite a few types of research researcher concerning Ag-TiO 2 nanocomposites used as photoactive materials 22-24 in many photoactive applications due to their localized surface plasmon resonance characteristics.…”

In this research Ag2Mn8O16 nanocrystals/TiO2 nanotubes, photoelectrodes were successfully prepared through anodization and annihilation steps, followed by electrodeposition of MnO2 and Ag in a three electrodes cell. The obtained photoelectrodes were dried, then annealed for crystallization, the morphology and structure of the fabricated electrodes were characterized via scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The light absorption and harvesting properties were investigated through UV–visible diffuse reflectance spectrum (DRS), photocatalytic performances were evaluated by degradation of 50 mL of Rhodamine B (5 mg L−1) under Xenon light irradiation for 2 h. Results illustrated that the fabricated photoelectrodes show remarkable photo-degradation properties of organic pollutants in aqueous mediums.
