📚 Carbon Nanoparticles | 碳纳米颗粒

Carbon nanoparticles are nanoscale forms of carbon, typically with at least one dimension below 100 nm. They include fullerenes, carbon nanotubes and graphene-related materials, and they show properties that differ sharply from bulk graphite or diamond.

碳纳米颗粒是纳米尺度的碳材料，通常至少有一个维度小于 100 nm。它们包括富勒烯、碳纳米管以及石墨烯相关材料，其性质与块体石墨或金刚石显著不同。

1. What Are Carbon Nanoparticles? | 什么是碳纳米颗粒？

In A-level chemistry, the term ‘carbon nanoparticles’ refers to discrete carbon structures with nanoscale dimensions, not simply small pieces of graphite. Because their size approaches the scale of atoms and molecules, quantum effects and a very high surface-area-to-volume ratio become important.

在 A-level 化学中，’碳纳米颗粒’指的是具有纳米尺度维度的独立碳结构，而不仅仅是细小的石墨碎片。由于它们的尺寸接近原子和分子尺度，量子效应以及极高的比表面积变得非常重要。

Common examples are fullerenes such as buckminsterfullerene C₆₀, single-walled and multi-walled carbon nanotubes, and graphene quantum dots. These species are often studied as carbon allotropes or as functional nanomaterials.

常见的例子包括富勒烯（如巴克敏斯特富勒烯 C₆₀）、单壁与多壁碳纳米管以及石墨烯量子点。这些物质通常作为碳同素异形体或功能性纳米材料来研究。

2. Carbon Allotropes at the Nanoscale | 碳的纳米尺度同素异形体

Carbon can form several allotropes because its valence electrons can adopt sp, sp² and sp³ hybridisation. Diamond is a 3D sp³ network, graphite is a layered sp² structure, and the nanoscale allotropes
