Supercapacitors (SCs) are potentially trustworthy energy storage devices, therefore getting huge attention from researchers. However, due to limited capacitance and low energy density, there is still scope for improvement. The race to develop novel methods for enhancing their electrochemical characteristics is still going strong, where the goal of improving their energy density to match that of batteries by increasing their specific capacitance and raising their working voltage while maintaining high power capability and cutting the cost of production. In this light, this paper offers a succinct summary of current developments and fresh insights into the construction of SCs with high energy density which might help new researchers in the field of supercapacitor research. From electrolytes, electrodes, and device modification perspectives, novel applicable methodologies were emphasized and explored. When compared to conventional SCs, the special combination of electrode material/composites and electrolytes along with their fabrication design considerably enhances the electrochemical performance and energy density of the SCs. Emphasis is placed on the dynamic and mechanical variables connected to SCs′ energy storage process. To point the way toward a positive future for the design of high‐energy SCs, the potential and difficulties are finally highlighted. Further, we explore a few important topics for enhancing the energy densities of supercapacitors, as well as some links between major impacting factors. The review also covers the obstacles and prospects in this fascinating subject. This gives a fundamental understanding of supercapacitors as well as a crucial design principle for the next generation of improved supercapacitors being developed for commercial and consumer use.

“…[1] In order to manage the environment more efficiently, catalysts emerge as the times require, and environmentally friendly photocatalytic methods have been developed rapidly. [2][3][4] The photocatalysis process refers to excited electrons transit to a higher energy level when incident light with energy higher than the bandgap illuminates the photocatalyst, thereby forming electron-hole pairs, which have a strong redox ability. Using photocatalysts in environmental remediation has the following advantages: 1) Thoroughly purify: it directly oxidizes organic pollutants completely into non-toxic and harmless substances.…”

With the serious pollution of water resources in the process of social development, green and environmentally friendly photocatalytic technology has gradually attracted widespread attention. Though photocatalytic theory and technology are relatively mature, the current research is mainly focused on powders and less on the photocatalytic membranes, and few real practical cases of photocatalysis are studied. To summarize and update these advanced studies, this paper introduces the latest progress in photocatalytic membranes including discussing the differences of photocatalytic mechanism between free and fixed photocatalytic systems and the design philosophy of photocatalytic membranes. At the same time, some common fabrication methods, including in situ growth, coating, spinning, casting, and foaming methods are analyzed. Besides, the photocatalytic performances of different photocatalytic membranes in the actual environment and their use conditions are explored. Finally, a critical view of future trends is included. The explanation of the photocatalytic mechanism, large‐scale production, and the practicality of photocatalytic products are all problems that need to be solved in the future.

Transition metal hydroxides are a kind of promising electrode material in electrochemical energy storage, but the poor conductivity limits their application. Lanthanides are good proton conductors and can usually improve the intrinsic conductivity of other materials. By integrating the merits of lanthanide elements and transition metal hydroxide, we designed lanthanum oxide nickel hydroxide composites (LONH) with unique ultrathin triangle nanosheet morphology via a controllable synthetic strategy for high-performance supercapacitors. When the LONH is used as positive electrode material in aqueous asymmetric supercapacitor, it reveals an energy density (107.8 W h kg−1 at 800 W kg−1), rate performance (86.9% retention at 4 kW kg−1) and outstanding cycle stability (more than 90% retention after 3,000 cycles). This work confirms that compositing La2O3 and Ni(OH)2 can significantly improve the supercapacitor performance of both pristine La2O3 and transition metal hydroxide composites. We hope this work would offer a good prospect for developing other lanthanide-transition metal hydroxide composites as an attractive class of electrode materials in electrochemical energy storage.
