Summary: In this study, a Bi2MoO6/TiO2 heterojunction was constructed to broaden light absorption and accelerate oxidation kinetics, leading to highly effective water splitting. The Bi2MoO6/TiO2 heterojunction exhibited significantly higher photocurrent density and better electron transfer properties compared to pristine TiO2, promoting the separation of electron-hole pairs. This work provides a novel strategy for TiO2-based heterojunction with great potential for photoelectrochemical water splitting applications.

Summary: This study designs and implements Bi2S3@α-Fe2O3 for enhancing photocurrent and photoelectrochemical water splitting efficiency, with a modulated interface by Sn doping in α-Fe2O3. The results show that the photocurrent of Bi2S3@(Sn)α-Fe2O3 after interface regulation is 6.7 times higher than that of the primary α-Fe2O3. The enhancement in photocurrent can be attributed to broadened light-harvesting, enhanced charge separation efficiency, and abundant oxygen vacancies.

Summary: Polycrystalline CuWO4 film is a promising photoanode material for PEC water splitting due to its small bandgap and excellent stability. However, its poor charge transfer characteristics limit its PEC performance. To improve the performance, two modification strategies are employed, using SnO2 as an electron transfer layer and cobalt phosphate as a co-catalyst. These modifications enhance the PEC activity by two times and exhibit excellent stability in a neutral electrolyte. Further developments of synthesis method and other modification strategies could potentially improve the performance.

Summary: Conventional lithium-ion batteries (LIBs) with liquid electrolytes have safety concerns in electric vehicles. All-solid-state batteries with solid-state electrolytes have been proposed, but face challenges of poor solid-solid contact and fast interface degradation. In this work, quasi-solid-state pouch cells were fabricated via in situ solidification of polymer electrolytes, showing stable electrochemical performance over 500 cycles. The excellent stability is attributed to the formation of a robust and compatible interphase, inhibiting interfacial side reactions and structural degradation. This work demonstrates the facile and cost-effective approach of in situ solidification for quasi-solid-state pouch cells with high performance and safety.

Summary: There is a growing interest in pi-d conjugated coordination polymers (CCPs) for energy storage due to their ability to facilitate rapid charge transfer. However, most reported CCPs for energy storage are based on 1D or 2D structures, and there are few 3D CCPs due to the challenge of constructing nonplanar coordination geometries. In this study, a triphenylene-catecholate-based 3D CCP (Mn-HHTP) was successfully synthesized and exhibited exceptional cycle life for multivalent Mg2+ ion storage, surpassing organic and inorganic electrode materials. Experimental and theoretical findings suggest that the semiquinone radicals at the HHTP ligands play a crucial role in storing Mg2+ ions. This research opens up new possibilities for designing 3D CCPs for long-life rechargeable magnesium-ion batteries.

Summary: All-solid-state lithium-sulfur batteries have the potential to be the next-generation energy storage solution due to their high theoretical energy density, low cost, and improved safety. However, the lack of understanding of their discharge products has hindered their widespread adoption. Through the use of advanced analytical techniques, it has been revealed that the discharge product of these batteries is not solely composed of Li2S but rather a mixture of Li2S and Li2S2. This finding has led to the proposal of an integrated strategy to improve the overall performance of these batteries.
