BaTiO3/CoO-PANI nanostructure has been demonstrated as the solar selective absorber coating for the first time. The effortless chemical methods and easily scalable techniques such as Hydrothermal, in-situ polymerization and spin coating were adopted for the fabrication of BaTiO3 nanorods and BaTiO3/CoO/PANI nanostructure for enhanced Hydrogen generation. The Electrochemical measurements were performed using a 1 kW xenon lamp (Newport) with its infrared wavelengths filtered out by water, and wavelengths below 420 nm removed by an optical filter, enabling measurements under visible light. The light irradiance, measured by a thermopile detector, was 100 mW/cm2. A monochromator (74,000, Newport) was used to investigate the monochromatic responses (for IPCE, applied bias photon to current efficiency (ABPE), and band gap energy measurements) of samples.1 the energy dispersive X-ray spectra and elemental mapping confirm the presence of the chosen elements in the nanostructure. Results indicate that the addition of the PANI nanoparticles to the BaTiO3/CoO-PANI nanostructure enhance the photocatalytic efficiency under natural sunlight irradiation. The optimized solar absorber coating of CoO-PANI nanostructure is highly promising for its selective optical properties |
