Abstract
Poultry manure is a significant source of ammonia (NH3) emissions, which not only poses detrimental impacts on human well-being and the ecological system, but also leads to economic losses in the agricultural industry. Herein, we modified corn straw (CS) with 1 wt% Pt/TiO2 catalysts using a low-temperature partial-oxidation technology to mitigate NH3 emissions from poultry manure. It was found that Pt/TiO2 can enable exothermic processes to occur at lower temperatures by reducing the activation energy. Under optimal modification conditions of 220 °C, the NH3 uptakes of modified CS samples were markedly greater compared to those of the original CS. Addition of 20-50% modified CS to poultry manure resulted in significant reductions of 54.1-98.6% in NH3 emissions compared to the control. Mechanistic studies indicate that NH3 adsorption on the modified CS is mainly driven by the presence of acidic and alkaline functional groups, while surface area and pore structure have a negligible effect. XPS combined with NH3-TPD reveals that the formation of amide and amine bonds contributes to the excellent stability of adsorbed NH3. H2-TPR, O2-TPD, and d-band theory suggest that strong metal-support interactions between Pt and TiO2 could be particularly crucial in catalyzing CS modification. This study proposes an environmentally sustainable and economically viable solution for abating NH3 emissions from poultry manure, thereby addressing crucial environmental and economic concerns in the agricultural sector.
