In mitigating environmental challenges, researchers at the Laser Processes and Spectroscopy Research Group within the BRIN Photonics Research Centre are at the forefront of harnessing the potential of light-activated photocatalysts. Nurfina Yudasari, a researcher in the group, underscores the pivotal role of photocatalysts in expediting chemical reactions with the aid of light.
A photocatalyst is a special material that can accelerate chemical reactions using light as its energy source. Imagine it as a tiny helper that speeds up chemical processes when exposed to light, similar to how a regular catalyst works without needing light.
Nurfina’s research introduced a revolutionary concept of photocatalytic materials that boost efficiency and find applications in advanced processes, particularly in converting various materials. During a recent webinar titled “Exploring the Potential of Laser Ablation Methods to Improve Photocatalyst Material Efficiency,” she asserted.
Nurfina articulated the research’s primary focus on addressing global environmental issues, including challenges related to waste and pollution, such as industrial textile waste and agricultural pesticide contamination. A key solution proposed is utilising materials characterised by high efficiency, rapid charge transfer, and reusability.
The researcher sheds light on five pivotal components that influence photocatalytic materials: types of light, material properties, optical characteristics, energy band gap, and shape and size. Nurfina emphasised that comprehending the impact of these five components is essential for determining suitable photocatalytic materials, particularly in the environmental sector.
The suggested solution involves deploying highly efficient photocatalysts across a broad light spectrum. Furthermore, the research accentuates the significance of charge separation to decelerate the recombination process, with the size and shape of materials playing a crucial role in influencing efficiency. Nanoparticle synthesis methods, including laser ablation and biosynthesis, are also spotlighted as integral aspects of the study.
In elucidating efficiency optimisation, Nurfina explained that comprehending the workings across a wide spectrum of light and the material’s band gap remains highly relevant. She underscored the importance of charge separation in slowing down the recombination process, highlighting the substantial influence of material size and shape on efficiency.
To ensure the sustained progress of this research, Nurfina extended an invitation for collaboration from a diverse array of stakeholders, including students and academics from universities. This collaborative effort aims to develop both knowledge and applications of photocatalytic materials. The integration of digital technologies, such as laser ablation techniques, exemplifies the innovative approaches being explored to address environmental concerns on a global scale effectively.
Amidst escalating global environmental challenges, the Laser Processes and Spectroscopy Research Group’s efforts showcase the potential of digital technologies and advanced materials in crafting sustainable and environmentally conscious solutions for the future.
Based on the previous report from OpenGov Asia, Indonesia has taken significant strides by leveraging technology to support national goals and address threats to its biodiversity. The Centre for Ecological and Ethnobiological Research (PREE) at the National Research and Innovation Agency (BRIN) has been at the forefront of preserving and recovering ecosystems and endangered species. Their approach incorporates cutting-edge technology and data collection strategies, particularly through the KEHATI initiative.
This underscores the pivotal role of effective data utilisation in creating a robust knowledge base, identifying population trends, understanding migration patterns, and quantifying the impact of climate change and human activities. Timely and accurate data facilitate efficient monitoring and swift responses to threats and contribute to better decision-making regarding resource allocation. Moreover, they play a crucial role in formulating effective, long-term conservation policies.
Looking ahead, the research conducted by Nurfina Yudasari and her team has presented a promising avenue for developing sustainable technologies. The innovative use of photocatalysts and laser ablation techniques addresses immediate environmental concerns and lays the groundwork for future advancements in green technology.
