With the ever‐increasing adaption of large‐scale energy storage systems and electric devices, the energy storage capability of batteries and supercapacitors has faced increased demand and challenges. The electrodes of these devices have experienced radical change with the introduction of nano‐scale materials. As new generation materials, heterostructure materials have attracted increasing attention due to their unique interfaces, robust architectures, and synergistic effects, and thus, the ability to enhance the energy/power outputs as well as the lifespan of batteries. In this review, the recent progress in heterostructure from energy storage fields is summarized. Specifically, the fundamental natures of heterostructures, including charge redistribution, built‐in electric field, and associated energy storage mechanisms, are summarized and discussed in detail. Furthermore, various synthesis routes for heterostructures in energy storage fields are roundly reviewed, and their advantages and drawbacks are analyzed. The superiorities and current achievements of heterostructure materials in lithium‐ion batteries (LIBs), sodium‐ion batteries (SIBs), lithium‐sulfur batteries (Li‐S batteries), supercapacitors, and other energy storage devices are discussed. Finally, the authors conclude with the current challenges and perspectives of the heterostructure materials for the fields of energy storage.

“…Despite these advantages, solar energy also exhibits intrinsic drawbacks, which significantly impede its large-scale and long-term application. 18,19 On the contrary, solar energy shows a low energy density. The average irradiation power of solar energy on the Earth's surface is only 1 kW•m −2 , which is much lower than that of fossil fuels or many other sustainable energy sources (e.g., wind energy and geothermal energy).…”

As a clean and renewable energy source, solar energy is a competitive alternative to replace conventional fossil fuels. Nevertheless, its serious fluctuating nature usually leads to a poor alignment with the actual energy demand. To solve this problem, the direct solar-to-electrochemical energy conversion and storage have been regarded as a feasible strategy. In this context, the development of high-performance integrated devices based on solar energy conversion parts (i.e., solar cells or photoelectrodes) and electrochemical energy storage units (i.e., rechargeable batteries or supercapacitors [SCs]) has become increasingly necessary and urgent, in which carbon and carbon-based functional materials play a fundamental role in determining their energy conversion/storage performances. Herein, we summarize the latest progress on these integrated devices for solar electricity energy conversion and storage, with special emphasis on the critical role of carbon-based functional materials. First, principles of integrated devices are introduced, especially roles of carbon-based materials in these hybrid energy devices. Then, two major types of important integrated devices, including photovoltaic and photoelectrochemicalrechargeable batteries or SCs, are discussed in detail. Finally, key challenges and opportunities in the future development are also discussed. By this review, we hope to pave an avenue toward the development of stable and efficient devices for solar energy conversion and storage.

It is reasonable to suspect that h + of PTCDA promotes the mineralization of organic pollutants.…”

Introducing the anion intermediate found with PTCDA into advanced oxidation processes (AOPs) overcomes the limitation of visible-light degradation. Stabilized PTCDA anionic intermediates act as electron reservoir to activate PMS to generate reactive oxygen species, thus improving the degradation rate of organic pollutants driven by visible light. At the same time, the photogenerated holes of PDI induce α and β scission with the unshared electron in organic molecules, and realize the deep mineralization of converting organic molecules to CO2. The BPA degradation rate of PTCDA /PMS is over 125.8 and 2.8 times as high as PTCDA photocatalysis and Co3O4/PMS, respectively. The BPA mineralization of PTCDA /PMS reaching ~ 88% outclasses Co3O4/PMS (~ 25%). In continuous flow reactor, it has a ~ 100% degradation and ~ 80% mineralization of BPA. The outstanding degradation in real water under solar light excitation indicates that PTCDA/PMS would be an intriguing system for non-toxic and harmless elimination of organic pollutants.
