As an attractive optical/heat dynamic management technology, reversible metal electrodeposition/dissolution electrochromism (RME-EC) shows many advantages, including high optical modulation amplitude, wide modulation band, and color neutrality, but also suffers from performance degradation because of uneven dendritic metal deposition as well as the formation/accumulation of isolated metal debris. In this paper, a facile RME-EC system is established in a green and affordable aqueous electrolyte, by making good use of the nondendritic Ni-Cu codeposition. Furthermore, an in situ self-healing strategy is further established by activating the Br/Br couple of the Br-containing electrolyte to improve the EC performance.

The pressing necessity to mitigate climate change and decrease greenhouse gas emissions has driven the advancement of heterostructure-based photocatalysts for effective CO₂ reduction. This study introduces a novel heterojunction photocatalyst formed by integrating potassium-doped polymeric carbon nitride (KPCN) with metallic Zn₃N₂, synthesized via a microwave-assisted molten salt method. The resulting Schottky contact effectively suppresses the reverse diffusion of electrons, achieving spatial separation of photogenerated charges and prolonging their lifetime, which significantly enhances photocatalytic activity and efficiency.

The transition towards a low-carbon future hinges on the advancement of Lithium-ion battery (LIBs) technology, which has spurred a significant demand for raw materials and the management of waste batteries containing hazardous substances. Developing efficient and environmentally friendly recycling strategies is essential to tackle these challenges. Here, we introduce a one-step green hydrometallurgical recycling of spent lithium-ion batteries' cathode on the basis of contact-electro-catalytic (CEC) process.

Trap-assisted charge recombination is one of the primary limitations of restricting the performance of organic solar cells. However, effectively reducing the presence of traps in the photoactive layer remains challenging. Herein, wide bandgap polymer donor PTzBI-dF is demonstrated as an effective modulator for enhancing the crystallinity of the bulk heterojunction active layers composed of D18 derivatives blended with Y6, leading to dense and ordered molecular packings, and thus, improves photoluminescence quenching properties.
