摘要:

以生活中常见的苦瓜头、香蕉皮等厨余物为原料,通过对文献的系统优化,将新型荧光材料——碳量子点的制备,创新性地开发为居家实验,中小学生甚至幼儿园小朋友在家长指导下,在家中用简单厨具即可轻松做出碳量子点,绿色安全,观感愉悦,趣味性强。同时,对居家碳量子点进行多色荧光调控、大型仪器表征和重金属离子检测等应用的探究,适合面向高中生、本科生开展源于生活的科普活动和综合实验。此外,就公众关心的量子、量子点等概念进行科学解读,辟谣“量子+生活”现象。本实验旨在以多种有趣形式开展梯度科普,生动诠释前沿概念,激发公众对厨余物资源化利用的热情,阐释化学来源于生活,又造福于生活的理念。

关键词: 碳量子点, 居家实验, 厨余物, 梯度科普, 重金属离子检测

Abstract:

A simple kitchen science experiment was designed to prepare carbon quantum dots using kitchen waste as raw materials, avoiding the hydrothermal method which is currently widely used in laboratories. The experiment requires common kitchen appliances, utensils, and waste material like fruit peelings that are typically discarded; this experiment provides a safe way for kids to prepare carbon quantum dots at home under adult supervision. It can also be carried out for high school students and undergraduates, encouraging them to learn key concepts about carbon quantum dots by introducing related instrumentation as well as understand the applicability of such dots toward the detection of heavy metal ions. Through such experiments, we attempt to engage students in cutting-edge research through fun, simple and frugal kitchen science experiments and aim to refute the rumors of "quantum + life".

Key words: Carbon quantum dots, Experiment to do at home, Kitchen wastes, Multi-level popularization of science, Heavy metal ions detection
