“…According to the reports from Plastics Europe, global plastic production has increased from 360 million tons in 2018 to 390 million tons in 2022. [52] Among plastic production, PE, including high density PE, low density PE, etc., represents the largest part of the plastic production around the world, about 30 % (Figure 2). With the use of PE in products such as plastic bags, packaging containers, pipes, and food packaging films, a large amount of PE waste has also been generated.…”

Due to the high power density, fast charging speed, and long cycling stability, supercapacitors have been developed rapidly in the area of electrical energy storage devices in the past decades. During the application of supercapacitors, it was found that the properties of the electrode material can greatly affect the supercapacitor performance. Recently, electrode materials based on polymer waste‐derived carbon materials (PWCM) have attracted much attention because of the low preparation cost, good electrode performance, and great benefits for environmental protection. This review aims to describe the recent research development and summarize the investigation state in the field of the PWCM electrodes prepared from polyethylene, polypropylene, polyethylene terephthalate, polystyrene, etc. The preparation method and the electrode performance of the PWCM electrodes are compared. The relationship among the preparation methods, material structure, and electrochemical performance of the PWCM electrodes was explored. Furthermore, the prospects for the application of the PWCMs were provided.

Solar seawater evaporation is a sustainable seawater desalination technology. However, how to convert low‐cost waste general plastics into highly efficient photothermal materials remains a challenge. By using the idea of “near‐infrared laser‐induced carbonization” at room temperature and in air atmosphere, polystyrene (PS) can be easily converted into graphene. Bismuth oxide (Bi2O3) catalyst is proven to efficiently convert laser energy into thermal energy and transmit it to the surrounding PS matrix, promoting carbonization. On this basis, by adjusting the catalyst content and the laser energy density per unit area, laser‐induced graphene (LIG) materials with high specific surface area, fast water transport, and high solar energy absorption efficiency can be obtained. Furthermore, the LIG materials are coated on the surface of natural bamboo with a capillary structure. This bilayer evaporation device has an evaporation rate of 1.51 kg m−2 h−1 and an energy conversion efficiency of 87.1% under irradiation of 1 sun. This work not only reveals the possibility of preparing high‐value‐added graphene materials from waste general‐purpose plastics, but also proves the application prospects of LIG materials in the field of solar seawater evaporation. This will provide a feasible approach for promoting the development of carbonization of waste general plastics.

“…29 This may be due to the abundant meso- and macro-pores, which would shorten the proton diffusion pathway and reduce the mass transfer resistance. 30 Meanwhile, the higher degree of graphitization and the strong interaction between Ru nanoparticles and LPNCS also promotes electron transfer. This was further confirmed by the Nyquist diagram results (Fig.…”
