Abstract

Increased NOx gas emissions from the technological development and urbanization from 20th century is one of the major air pollutants. The nitrogen as an essential nutrient for plant’s growth and development can be obtained/adsorbed from air containing nitrogen compounds. Photocatalytic absorption is a method that is used to convert atmospheric nitric oxide into nitrate which is the desired form of nitrogen that is absorbed and assimilated by most plants. In this study, photocatalytic adsorption efficiency of TiO2 and Ca-doped TiO2 is analysed. Along with, materials the synthesis method is also compared. The synthesized materials were evaluated using particle size analyser for particle size, FTIR for bonds in the samples, SEM for morphology, EDAX for elemental composition, NO3- meter for NO3- conversion ability of the samples. Calcium doping over TiO2 enhances the NO3- conversion ability of undoped TiO2. Treatment 3 (R-Leaf) performed significantly better in producing nitrate under outdoor light conditions, demonstrating its potential to be utilised in crop production as a replacement for synthetic nitrogen.
