“…Nevertheless, liquidphase exfoliation (LPE) method is difficult to be used on a broad scale, because of the poor solution dispersibility of GDY in most solvents, although damage‐free GDY nanosheets were obtained by lithium‐intercalation in aqueous solutions [16–17] . Graphdiyne oxide (GDYO) nanosheets are almost obtained via exfoliation and oxidation from graphdiyne using the strong oxidizing agent such as H 2 O 2 /H 2 SO 4 or H 2 SO 4 /HNO 3 , [18–20] which exhibit a suitable LUMO level for water splitting, [21] and excellent light‐to‐heat conversion performance, [22–23] especially for near‐infrared irradiation [24–25] . Moreover, the introduction of abundant carboxyl, hydroxyl and epoxy functional groups on GDYO nanosheet can promote its hydrophilicity and improving antibacterial activity [26] .…”

Graphdiyne (GDY) is a new two‐dimensional ordered carbon oxide composed of sp and sp2 hybrid carbon atoms. It holds great application potential due to the uniformly distributed pores and design flexibility. However, the present preparation technology is still limited to obtain graphdiyne oxide (GDYO) nanosheets from oxidation of exfoliated GDY, just depending on strong corrosive acid as an oxidant. Herein, this work reports a simple, efficient, liquid‐phase exfoliation strategy, in which supercritical carbon dioxide (SC CO2) was first proposed to directly exfoliate GDY and prompt their oxidation into ultrathin GDYO nanosheets. The introduced CO2 molecules can cause the increase of bond lengths and bending degree of the intermediate C bond, and it can weaken and further break acetylenic bonds, which is proved by density functional theory (DFT) calculations. Meanwhile, experimentally GDYO nanosheets also show excellent light‐to‐heat conversion performance with a photothermal conversion efficiency of 63.95%. Therefore, this work provides a new environmentally friendly way to design and develop advanced carbon‐based materials and indicates GDYO‐based materials fundamentally significant in biomedicine, environmental governance.

“…The photopromoted hydrogenation of olefin will decrease the selectivity of light olefins and increase the paraffin selectivity, which makes direct irradiation unfavorable when olefins are the target products. [ 42,92 ] Therefore, PTC catalysts should be carefully designed, and it is not wise to apply “photothermal” blindly.…”

With the development of society, energy shortage and environmental problems have become more and more outstanding. Solar energy is a clean and sustainable energy resource, potentially driving energy conversion and environmental remediation reactions. Thus, solar‐driven chemistry is an attractive way to solve the two problems. Photothermal chemistry (PTC) is developed to achieve full‐spectral utilization of the solar radiation and drive chemical reactions more efficiently under relatively mild conditions. In this review, the mechanisms of PTC are summarized from the aspects of thermal and non‐thermal effects, and then the interaction and synergy between these two effects are sorted out. In this paper, distinguishing and quantifying these two effects is discussed to understand PTC processes better and to design PTC catalysts more methodically. However, PTC is still a little far away from practical. Herein, several key points, which must be considered when pushing ahead with the engineering application of PTC, are proposed, along with some workable suggestions on the practical application. This review provides a unique perspective on PTC, focusing on the synergistic effects and pointing out a possible direction for practical application.

“…Compared to conventional photocatalysts working at room temperature, photothermal catalysts typically have a broader solar spectrum and a much higher local reaction temperature [21]. Besides, photothermal catalysis demonstrates the undeniable advantages of low cost and cleanliness with solar energy as a cleaner heat source than the fossil energy-driven thermal catalysis [22]. The above promotes the broad application of photothermal nanomaterials in diversified realms, especially in environmental and catalytic applications [23].…”

Solar energy is a green and sustainable clean energy source. Its rational use can alleviate the energy crisis and environmental pollution. Directly converting solar energy into heat energy is the most efficient method among all solar conversion strategies. Recently, various environmental and energy applications based on nanostructured photothermal materials stimulated the re-examination of the interfacial solar energy conversion process. The design of photothermal nanomaterials is demonstrated to be critical to promote the solar-to-heat energy conversion and the following physical and chemical processes. This review introduces the latest photothermal nanomaterials and their nanostructure modulation strategies for environmental (seawater evaporation) and catalytic (C1 conversion) applications. We present the research progress of photothermal seawater evaporation based on two-dimensional and three-dimensional porous materials. Then, we describe the progress of photothermal catalysis based on layered double hydroxide derived nanostructures, hydroxylated indium oxide nanostructures, and metal plasmonic nanostructures. Finally, we present our insights concerning the future development of this field.
