Abstract

Abstract The palladium (Pd)-catalysed reaction has attracted much attention, making Pd the most valuable of the four major precious metals. Several different forms of Pd can be used as a catalyst; nanoparticles (NPs) have the advantage of a high surface area:volume ratio. Since the chemical production of Pd NPs is not environmentally friendly, biological synthesis interest has grown. However, the production mechanism remained unknown in several cases and was recently described for the electroactive bacterium Shewanella oneidensis MR-1. The application of these green synthesised NPs was established in different fields. This review discusses the production pathway and the novel biological-inspired methods to produce tailored biogenic palladium nanoparticles (bio-Pd NPs), with their broad application fields as biogenic nanocatalysts. Two significant applications – reductive bioremediation of persistent organic contaminants and energy-producing microbial fuel cells – are discussed in detail. The current challenges in optimising bio-Pd NPs production and the potential research directions for the complete utilisation of its novel catalytic properties are highlighted.

钯纳米颗粒的生物合成:新的生产方法和应用

摘要钯（Pd）催化反应备受关注，使钯成为四种主要贵金属中最有价值的一种。几种不同形式的Pd可以用作催化剂；纳米颗粒（NP）具有高表面积与体积比的优点。由于Pd NPs的化学生产对环境不友好，生物合成的兴趣越来越大。然而，在一些情况下，其产生机制仍然未知，最近对电活性细菌谢瓦内拉oneidensis MR-1进行了描述。这些绿色合成的纳米颗粒在不同领域的应用已经确立。这篇综述讨论了制备定制的生物钯纳米颗粒（bio-Pd-NPs）的生产途径和新的生物启发方法，以及它们作为生物纳米催化剂的广泛应用领域。两个重要应用 – 持久性有机污染物的还原生物修复及能量产生微生物燃料电池 – 详细讨论。重点介绍了优化生物钯纳米粒子生产的当前挑战以及完全利用其新型催化性能的潜在研究方向。生物钯纳米粒子的新应用

期刊介绍： The bimonthly journal Nanotechnology Reviews provides a platform for scientists and engineers of all involved disciplines to exchange important recent research on fundamental as well as applied aspects. While expert reviews provide a state of the art assessment on a specific topic, research highlight contributions present most recent and novel findings. In addition to technical contributions, Nanotechnology Reviews publishes articles on implications of nanotechnology for society, environment, education, intellectual property, industry, and politics.
