Current trends in carbon-based quantum dots development from solid wastes and their applications
Urbanization and a massive population boom have immensely increased the solid wastes (SWs) generation and are expected
to reach 3.40 billion tons by 2050. In many developed and emerging nations, SWs are prevalent in both major and small cities. As a result, in the current context, the reusability of SWs through various applications has taken on added importance.
Carbon-based quantum dots (Cb-QDs) and their many variants are synthesized from SWs in a straightforward and practical
method. Cb-QDs are a new type of semiconductor that has attracted the interest of researchers due to their wide range of
applications, which include everything from energy storage, chemical sensing, to drug delivery. This review is primarily
focused on the conversion of SWs into useful materials, which is an essential aspect of waste management for pollution
reduction. In this context, the goal of the current review is to investigate the sustainable synthesis routes of carbon quantum
dots (CQDs), graphene quantum dots (GQDs), and graphene oxide quantum dots (GOQDs) from various types SWs. The
applications of CQDs, GQDs, and GOQDs in the diferent areas are also been discussed. Finally, the challenges in implementing the existing synthesis methods and future research directions are highlighted.
