Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 7, 2025

Abstract Simulating the characteristics and achieving specific functions of biological systems are stirring but challenging. Developing biomimetic leaves (BLs) with such as photosynthesis, transpiration, solar spectrum similarity receives great attention. With increasingly developed hyperspectral imaging techniques, though BLs for have made significant strides, they still grappling low single function. In this review, first, tissue optical path natural analyzed. Then, spectral up‐to‐date pigments functional multifunctional summarized. The importance is highlighted. Notably, organic–inorganic hybrid vibrant colors multifunction, show boundless promise. At last, insights into perspectives challenges on provided. This review contributes profound materials toward plants.

Hydroxyl combined with nitrogen on biomass carbon promotes the electrocatalytic H\(_{2}\)O\(_{2}\) selectivity

Journal of Metals Materials and Minerals, Journal Year: 2025, Volume and Issue: 35(1), P. e2216 - e2216

Published: Feb. 22, 2025

Elevating the selectivity of two-electron oxygen reduction reaction (2e‒ ORR) is challenging. Herein, hydroxyl combined with nitrogen on biomass carbon exhibits a high H2O2 over wide potential range 0 V to 0.5 vs. RHE, which nearly 97% at 0.3 RHE. The combination and improves adsorption desorption intermediates, finally changing pathway promoting 2e‒ ORR. Faradaic efficiency (FE) reaches 98% Furthermore, typical organic pollutants were degraded site in flow cell. This work illustrates

Enabling highly reversible Zn anode via an interfacial preferentially adsorbed additive containing nucleophilic groups

Microstructures, Journal Year: 2025, Volume and Issue: 5(2)

Published: March 21, 2025

The cyclability and reversibility of aqueous zinc-ion batteries (AZIBs) are severely hampered by the safety concerns arising from Zn dendrite growth. Therefore, a stable anode with inhibited dendrites side reactions is crucial for AZIBs. Herein, we utilized methyl acetoacetate (MA) as an additive to prevent growth enable highly reversible anodes. Benefiting nucleophilic groups (carbonyl groups) in MA, MA molecules can preferentially adsorb on anode/electrolyte interface (AEI), forming molecular protective layer. Such layers not only regulate migration deposition zinc ions, but also inhibit induced decomposition free H2O at AEI. symmetric cell addition achieves long-term cycling stability 1,500 h 2 mA cm-2 capacity mAh cm-2. In addition, Zn//NVO full using MA-contained electrolyte demonstrates high specific (138.4 g-1) outstanding retention (92.8% after 600 cycles) 1 A g-1. This work provides principle use ester-based additives suppress durable metal
