چکیده
Ammonia is commonly synthesized through the Haber-Bosch process, which produces large amounts of CO2 emissions as it carried out at extreme temperatures and pressures. An alternative technology needed to synthesize ammonia consumes less energy environmentally friendly. In this research, a Dye-Sensitized Solar Cell Photoelectrochemical tandem system (DSSC-PEC) was developed for nitrogen reduction reaction (NRR) into ammonia. PEC cells utilized BiVO4/TiO2 Nanotube (BiVO4/TiO2NT) photoanode water oxidation. BiVO4/TiO2NT by successive ionic layer adsorption (SILAR) with cycles variation 10, 15, 20 cycles. The optimization method (20s) gave highest photocurrent 0.352 mA/cm2. As cathode where takes place, Ti3+/TiO2NT used. DSSC based on TiO2NT/N719 an efficiency 1.13% used booster in reaction. Using electrodes area 3 cm2, under visible light irradiation while dark cathode, rate production, analyzed using phenate 0.022 µmol.h−1.cm−2 solar chemical conversion (SCC) 0.003%.
