Engineering of the luminescent properties for graphene quantum dots (GQDs) presents two enormous challenges: 1) The bandgap of GQDs is mainly determined by structural defects (size, shape, and the fraction of sp2 and sp3 domains), which results in non-stoichiometric nature; 2) the preparation methods limit the achievement of an accurate chemical structure of GQDs, leading to many controversial explanations...
Efficient capture of solar energy will be critical to meeting the energy needs of the future. Semiconductor photocatalysis is expected to make an important contribution in this regard, delivering both energy carriers (especially H2) and valuable chemical feedstocks under direct sunlight. Over the past few years, carbon dots (CDs) have emerged as a promising new class of metal‐free photocatalyst, displaying...
