Green Synthesis of Palladium Nanoparticles Using Medicinally Important Plant Extracts
摘要
Nanoparticles (NPs) are tiny materials sized between 1 and 100 nm, exhibiting unique physical and chemical characteristics due to their size-dependent properties. They have a large surface area relative to their volume. NPs have various applications in manufacturing, particularly in catalysis and imaging, as well as in the medical industry, energy production, research, and pollution control. One such NPs is palladium (Pd), a key component of many catalysts, offering a larger surface area. Recent advancements in fuel cell technology have led to a significant increase in the cost of Pd, which has risen by five times over the last decade, thereby increasing demand for PdNPs. PdNPs possess superior physicochemical characteristics at the nanometre level, expanding their utility in hydrogen detection, storage, and biomedical applications. This review focuses on plant-mediated biogenic synthesis technologies for PdNPs, primarily targeting size and shape control to tailor the properties of the synthesized material. The green synthesis of PdNPs has gained popularity as a highly efficient, eco-friendly technology with diverse applications in catalysis, environmental remediation, and medicine.
