Bi2MoO6, an eye‐catching member of the Aurivillius family, has recently drawn extensive interest in visible‐light‐driven photocatalytic environmental remediation and energy conversion by right of its salient features such as fascinating layered structure, appropriate band potentials, nontoxicity, and excellent thermal and chemical inertness. Enormous endeavors have been devoted to breaking out of its inherent flaws to further improve its unsatisfactory photocatalytic activity. Herein, a general overview is given to summarize the recent advances in the surface/interface modification strategies for fabricating highly active Bi2MoO6‐based nanostructures. The means and mechanisms of surface and interface modifications are concluded and discussed in some detail, including morphology regulation, facet control, defect engineering, metal deposition, and semiconductor combination. Moreover, representative photocatalytic applications of Bi2MoO6‐based nanostructures are also dialectically introduced and categorized into two main types: environmental contaminant removal and renewable energy development. Herein, the current research status of Bi2MoO6‐based photocatalysts is highlighted, informing a broad range of researchers abreast of these significant fields, as well as casting a glance at the challenges and potential of this material.

“…CDs are new class of carbonbased nanomaterials (different from fullerenes, graphenes, carbon nanotubes, and other carbon allotropes) which were casually discovered by Xu et al [5]. Since then, they have become an object of great research interest in the materials science community [6][7][8]. In fact, compared to conventional inorganic semiconductor-based quantum dots, they exhibit peculiar features, like high photostability, nontoxicity, water solubility, and lowcost [9][10][11][12][13][14][15][16][17][18]; see Figure 1.…”

Carbon quantum dots (CDs) are a new class of fluorescent carbonaceous nanomaterials that were casually discovered in 2004. Since then, they have become object of great interest in the scientific community because of their peculiar optical properties (e.g., size-dependent and excitation wavelength-dependent fluorescence), which make them very similar to the well-known semiconductor quantum dots and suitable for application in photovoltaic devices (PVs). In fact, with appropriate structural engineering, it is possible to modulate CDs photoluminescence properties, band gap, and energy levels in order to realize the band matching suitable to enable the desired directional flow of charge carriers within the PV device architecture in which they are implanted. Considering the latest developments, in the present short review, the employment of CDs in organic photovoltaic devices (OPVs) will be summarized, in order to study the role played by these nanomaterials in the improvement of the performances of the devices. After a first brief summary of the strategies of structural engineering of CDs and the effects on their optical properties, the attention will be devoted to the recent highlights of CDs application in organic solar cells (OSCs) and in dye sensitized solar cells (DSSCs), in order to guide the users towards the full exploitation of the use of these nanomaterials in such OPV devices.

Energy matching strategy is verified as an effective method for significant improvement of evaporation rate in direct solar steam generation (DSSG). By adjusting the solid-liquid interface through bilayer structure, the water transport speed from reservoir to evaporation surface is controlled to reduce the required energy (RE) for closely matching with that of input energy (IE). The highest evaporation rate can reach up to 2.22 kg m À2 h À1 under one-sun illumination, which is improved by 40% through energy matching. A solar-to-vapor energy conversion efficiency of 93.2% is obtained. It is also highly effective in practical applications including desalination, sewage treatment, oil-water separation, and heavy metal ions treatment. This concept displays a balance between the energy needed for water waiting to be evaporated and the IE. It can inspire more ideas for researchers to accelerate the development of DSSG.
