Abstract
Diesel exhaust gases such as NOx and SOx are significant contributors to pollution in today’s atmosphere. The International Convention for the Prevention of Pollution from Ships (MARPOL) Annex VI has a tiered system for regulating these gases from marine diesel engines. The current standard, Tier III, limits the NOx emissions based on a vessel’s horsepower. Our approach is based on perovskite photovoltaic architecture using fluorine-doped tin oxide (FTO) glass substrates coated with four layers applied by doctor blading. The first two being a TiO2 layer and a mesoporous TiO2 layer, then aperovskite layer and V3O7 layer respectively. The perovskite layer solution was formed from 0.3481g FAI, 1.0125g PbI2, 0.1465g PbBr2, and 0.0449g methylammonium bromide (MABr) in 2mL (4DMF:1DMSO) and 105.2 μL cesium iodide (CsI) solution (9.7430 g CsI in 25mL DMSO) to activate in a conical vial. The mixed-valent vanadium oxide layer was formed by hydrothermal synthesis of 0.2275g vanadium oxide (V2O5) and 0.005g 4-aminophenol (H2NC6H4OH) at 180°C for 48 hours. This poster highlights the substrates and materials formed and tested via XRD, XRF, and artificial exhaust seawater NO3- and NO2- Hach spectrometry.
