Quantum dots (QDs) are getting special attention due to their commendable optical properties and applications. Conventional metal-based QDs have toxicity and non-biodegradability issues, thus it becomes necessary to search for renewable precursor molecules for QDs synthesis. In recent years, biomass-based carbon rich QDs (CQDs) have been introduced which are mainly synthesised via carbonization (pyrolysis and hydrothermal treatment). These CQDs offered higher photostability, biocompatibility, low-toxicity, and easy tunability for physicochemical properties. Exceptional optical properties become a point of attraction for its multifaceted applications in various sectors like fabrication of electrodes and solar cells, conversion of solar energy to electricity, detection of pollutants, designing biosensors, etc. In recent years, a lot of work has been done in this field. This article will summarize these advancements along in a special context to biomass-based QDs and their applications in energy and the environment.
量子点（QDs）由于其出色的光学性质和应用而受到特别关注。传统的基于金属的 QDs 存在毒性和不可生物降解性问题，因此有必要寻找可用于 QDs 合成的可再生前体分子。近年来，已经引入了基于生物质的富碳 QDs（CQDs），它们主要通过碳化（热解和水热处理）合成。这些 CQDs 具有更高的光稳定性、生物相容性、低毒性和易于调节物理化学性质。其出色的光学性质使其在各个领域的应用变得多样化，例如制造电极和太阳能电池、将太阳能转化为电能、检测污染物、设计生物传感器等。近年来，在这一领域已经开展了大量工作。本文将在一个特殊的背景下，对基于生物质的 QDs 及其在能源和环境中的应用进行总结。
