Abstract

Enormous advances have been made in the synthesis of metal nanoparticles (NPs) affording a high degree of control over their size, shape, and composition. In recent years, a growing effort has been dedicated to incorporating principles of green chemistry in different aspects of NPs, ranging from reagents/solvents to their fate in the environment. In this report, we focus on the use of Cyrene (dihydrolevoglucosenone) as an alternative green solvent for the synthesis of metal NPs. We begin with the synthesis of Ag NPs, given their prominence in the literature. Through control reactions, we show that Cyrene has a dual role of solvent and reducing agent. Additionally, the conversion yield for the Ag NPs synthesis was studied with respect to temperature and the Ag precursor. We then expand on the synthetic methodology to access Pd, Pt, and Bi NPs. The functionality of the synthesized NPs is assessed by employing them as electrocatalysts for furfural reduction and the hydrogen evolution reaction. We envision the use of Cyrene as a green solvent can be extended toward the synthesis of NPs of other metals and classes of materials.

芘作为合成金属纳米粒子的溶剂
金属纳米粒子(NPs)的合成技术取得了巨大进步,可以高度控制其大小、形状和成分。近年来,越来越多的人致力于将绿色化学原理融入到 NPs 的各个方面,从试剂/溶剂到 NPs 在环境中的归宿,不一而足。在本报告中,我们将重点讨论使用芘(二氢左旋葡烯酮)作为合成金属 NPs 的替代绿色溶剂。鉴于 Ag NPs 在文献中的重要地位,我们将从合成 Ag NPs 开始。通过控制反应,我们发现芘具有溶剂和还原剂的双重作用。此外,我们还研究了合成 Ag NPs 的转化率与温度和 Ag 前体的关系。然后,我们扩展了合成方法,以获得 Pd、Pt 和 Bi NPs。通过将合成的 NPs 用作糠醛还原和氢气进化反应的电催化剂,对其功能进行了评估。我们设想,芘作为绿色溶剂的用途可以扩展到其他金属和材料类 NPs 的合成。

期刊介绍: The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
