“…Likewise, the less intense cathodic peak at 0.03 V, resulting from the negative sweep could be correlated with the reduction phenomena taking place over the ZnInO: In 2 O 3 layers. So, under illuminated conditions the superficial In 3+ ions distributed on the surface of nanoplates might undergo rapid reductive decomposition, to result with metallic In [20,21]. This phenomenon might have aided in establishing an excellent electrical contact between the active materials and further assisted in improving the electron transfer kinetics across the hybrid p-n junctions.…”

“…Such processes are usually attributed to the migration of charge carriers in the lms, where In 2 O 3 has been reported to partially reduce to metallic In. [30][31][32] The resulting excess In atoms might tend to occupy the interstitial site of In 2 O 3 , resulting in the generation of conduction electrons, whose reduction reaction might be assimilated through eqn (2):…”

Solution processed organic-inorganic bulk hybrid heterostructures are nowadays considered as the most promising elements to perform efficient optoelectronic functions. In this regard, In2O3 based hybrid heterostructures were fabricated using polypyrrole and their role as efficient interfacial layers was studied using polypyrrole/ZnO nanowires. The In2O3 nanostructures were synthesized through a facile wet chemical approach at an average scale of less than 10 nm in cubic phase. The presence of O and In related defects was studied through emission spectra; these were also found to exhibit their predominance in Raman measurements. The n-type characteristics and donor density value of around 10(20) cm(-3) were evaluated for the In2O3 specimens via Mott-Schottky plots. The role of In2O3 nanostructures as active/interfacial layers was then studied using the current-voltage characteristics obtained across the hybrid heterostructures made of polypyrrole/In2O3, polypyrrole/ZnO and polypyrrole/In2O3/ZnO. Organic-inorganic p-n diodes were obtained via in situ chemical polymerization, drop casting and hydrothermal routes. Cyclic voltammograms and Nyquist plots were used to study the reduction mechanism taking place in the nanostructures that actually results with the formation of metallic In, which plays a vital role in establishing the required conduction electrons. The same has been reasoned for the improved rectification characteristics observed across the diodes.

“…Second, in the pores of PAM and the interface, where the H 2 SO 4 flux does have not access, and the pH of solution is high, the PbO 2 is reduced to PbO n (n Ͻ 1.4). 16 The PbO n (n Ͻ 1.4) has high specific resistance, 12 which causes the high polarization of the electrode ͑Fig. 3 and 4͒.…”

The capacity of the positive plate of the lead-acid battery is determined by the number of the active centers in positive active material (PAM) where the reaction PbO2→PbSO4 proceeds and by the resistance of the interface corrosion layer false(CLfalse)+AMCL (thin PAM layer interconnecting the PAM and the CL). It was established that the number of the active centers is high if the positive plate discharge is performed with low current and if the charge (at the initial period) is performed with high current. During discharge the active centers from the outer layer of the plate are exhausted and the reaction of the PbO2 reduction approaches the inner part of the plate near the interface and the interface itself. If the pH of the pore solution is low the reduction of the PbO2 proceeds to PbSO4. At the subsequent charge with sufficiently high current a maximum appears on the potential transient. When the H2SO4 flux to the interface is impeded, the pH of the solution in the pores in the interface is high and the reduction of the PbO2 proceeds to PbOn false(1
