In a fascinating twist of agricultural innovation, researchers have harnessed the natural properties of mangosteen peel to create a highly effective self-cleaning nanocomposite. This development, led by Maisari Utami from the Department of Chemistry at Universitas Islam Indonesia, could have significant implications for farming practices, particularly in pest management and crop maintenance.
The team’s work revolves around the synthesis of a titanium dioxide/reduced graphene oxide (TiO2/rGO) nanocomposite using mangosteen peel extract as a bioreductive agent. The process not only showcases the peel’s remarkable reducing capabilities but also emphasizes the potential of biowaste in creating valuable materials. “Using natural resources like mangosteen not only provides an eco-friendly solution but also adds value to agricultural byproducts,” Utami explained.
This innovative nanocomposite exhibits impressive photocatalytic properties, particularly in the degradation of methylene blue, a common pollutant. Under visible light, the TiO2/rGO nanocomposite achieved a staggering 99.20% degradation rate, outperforming traditional methods that often rely on harsher UV light. This could mean a game-changer for farmers looking to maintain clean water sources and reduce chemical usage in their fields.
The research indicates that the TiO2/rGO material becomes more hydrophilic after exposure to light, a feature that could enhance its self-cleaning capabilities. In practical terms, this means that surfaces treated with this nanocomposite could repel dirt and contaminants, leading to less frequent cleaning and maintenance. “Imagine the savings in labor and resources for farmers who can rely on self-cleaning surfaces,” said Utami, highlighting the commercial potential of their findings.
With a high surface area of 95.845 m²/g and a crystal size of just 10.439 nm, the material’s design is optimized for efficiency. This could open doors to applications beyond agriculture, such as in water treatment systems or even in the construction of self-cleaning buildings, further extending the reach of this research.
Published in ‘Results in Engineering’, this study not only sheds light on the promising capabilities of TiO2/rGO nanocomposites but also underscores the importance of sustainable practices in agricultural innovation. As the sector increasingly seeks greener solutions, this research stands as a testament to how nature can inspire cutting-edge technology. The future of farming may very well be intertwined with the humble mangosteen, showcasing how traditional knowledge and modern science can come together to create sustainable solutions.
