Dataset for "Electrodeposited p-Cu2O Films – Role of Redox-Active Compounds Under Photoelectrochemical Operation Revisited"
<p>The p-type semiconducting copper oxides CuO and Cu2O are of interest for the conversion of solar energy due to their medium wide bandgap. The position of their conduction band should allow for reductive processes in junctions with electrolytes under irradiation. In this work, on Cu2O, the efficiency of several such processes in competition with self-reduction was studied.<br>Thin films of Cu2O were synthesised via potentiostatic electrodeposition on FTO (fluorine doped SnO2 on glass) using aqueous electrolytes. Deposition parameters (electrolyte composition, electrode potential, temperature) had a great influence on electrode properties (phase purity, preferential orientation). Electrodeposited Cu2O films were p-type. In junctions with aqueous electrolytes, under electrical bias, cathodic and photocathodic currents passed which increased dramatically when reducible redox compounds were added. The influence of various redox couples (O2, H2O2, methylviologen) and their concentration in the electrolyte on the stability of the electrodes was studied.<br>Long time experiments showed that oxygen saturated and H2O2 containing electrolytes gave rise to constant photocurrents and no alteration of the electrodes was found by XRD. With the investigated redox couples, no product of interest was produced.</p>

Data from: Electrodeposition of iron from 1-ethyl-3-methylimmidazolium trifluoromethanesulphonate and reverse microemulsions of Triton X-100
<p>Electrodeposition of iron (Fe) was investigated in three different media: namely, a hydrophilic ionic liquid (IL), 1-ethyl-3-methylimmidazolium trifluoromethanesulphonate, conventional reverse microemulsion (RME)/reverse micellar solution, and IL based reverse microemulsion of a non-ionic surfactant, Triton X-100 with a view to achieving control over size, shape, and morphology of the electrodeposited iron. Electrochemical behavior of Fe<sup>2+ </sup>was studied using cyclic voltammetric technique with a copper electrode as the working electrode. Electrochemical reduction of Fe<sup>2+</sup> in all the studied media was found to be an electrochemically irreversible, diffusion-controlled process. Successful potentiostatic electrodeposition of metallic iron was performed in all the studied media on copper substrate using bulk electrolysis method. The obtained iron electrodeposits were characterized using a scanning electron microscope (SEM) and an x-ray diffractometer (XRD). The controlled diffusion of Fe<sup>2+</sup> towards electrode surface<sup> </sup>in all the media resulted in the formation of nanoparticles of iron, but compact layers of granular nanoparticles could be achieved from both the conventional and IL based RME systems. The IL based microemulsions synergistically combined the advantageous features of both the IL and RME and showed the prospect of tuning the size, shape, and morphology of the electrodeposited iron.</p>

Phases evolution and photocatalytic activity of Cu2O films electrodeposited from a non-pH-adjusted solution
<p>A pure-phase Cu<sub>2</sub>O film photocatalyst was successfully prepared by the electrodeposition technique from a non-pH-adjusted solution. To investigate the phase evolution and photocatalytic activity of the film, the electrodeposition was conducted at different deposition temperatures. Photocatalytic activity of the films was evaluated from methylene blue (MB) dye degradation. The Cu<sub>2</sub>O phase initially appeared at room temperature and its fraction was found to increase with increasing the deposition temperature, while the impurity phase was successfully diminished. A pure Cu<sub>2</sub>O film with a narrow optical bandgap energy of 1.96 eV was obtained at 75°C. The multi-faceted crystals were found to form at 45°C and became a truncated octahedral structure that possessed {111} and {100} facets as deposition temperature further increased. A preferred orientation growth of {110} facet, which is known to possess a relatively high surface energy, was produced at 75°C. The performance of MB photodegradation enhanced gradually by increasing the deposition temperature. The increase of photocatalytic activity could be attributed to the rise of photoelectrochemical response and the decrease of resistance charge transfer because of narrowing bandgap energy, increasing Cu<sub>2</sub>O fraction, and growing a relatively high catalytic activity facet which had escalated redox reaction that decomposed MB at the photocatalyst-solution interface.</p>

Facile Electrodeposition-Based Chemosensors Using PANI and C-Hybrid Nanomaterials for the Selective Detection of Ammonia and Nitrogen Dioxide at Room Temperature - Dataset
<p>Sensor systems for monitoring indoor air quality are vital for the precise quantification of the mechanisms which lead to the deterioration of human health, with a typical person spending an average of 20 h a day in an enclosed space. Thus, a series of layered chemoresistive sensors, obtained by the facile electrodeposition of carbon nanomaterial-enhanced PANI composites, have been tested for the selective detection of two core indoor pollutants: ammonia and nitrogen dioxide. The sensors were tested with respect to sensitivity and selectivity to the target gasses, with performance being assessed based on response linearity and repeatability at room temperature. Of the tested sensors, two have been identified as having an adequate performance on ammonia, with sensitivities of up to 96.99% and resolutions of up to 0.85 ppm being observed, while on nitrogen dioxide, despite the successful sensor having a lower sensitivity, 10.71%, it has shown high resolution, 1.25 ppm, and linearity over a large concentration domain. These high performances highlight the viability of multi-layers chemosensors based on the electrodeposition of nanomaterial-enhanced conductive polymers for the detection of pollutant gasses, with finetuning of the detection layer allowing the accurate monitoring of a wide range of gasses.</p>
