Electrochemical conversion of nitrate (NO3–) into ammonia (NH3) recycles nitrogen and offers a route to the production NH3, which is more valuable than dinitrogen gas. However, today's development NO3– electroreduction remains hindered by lack mechanistic picture how catalyst structure may be tuned enhance catalytic activity. Here we demonstrate enhanced reduction reaction (NO3–RR) performance on Cu50Ni50 alloy catalysts, including 0.12 V upshift in half-wave potential 6-fold increase...
Rechargeable aqueous Zn-I2 batteries (ZIB) are regarded as a promising energy storage candidate. However, soluble polyiodide shuttling and rampant Zn dendrite growth hamper its commercial implementation. Herein, hetero-polyionic hydrogel is designed the electrolyte for ZIBs. On cathode side, iodophilic polycationic (PCH) effectively alleviates shuttle effect facilitates redox kinetics of iodine species. Meanwhile, polyanionic (PAH) toward metal anode uniformizes Zn2+ flux prevents surface...
Abstract The practical implementation of aqueous zinc‐iodine batteries (ZIBs) is hindered by the rampant Zn dendrites growth, parasite corrosion, and polyiodide shuttling. In this work, ionic liquid EMIM[OAc] employed as an all‐round solution to mitigate challenges on both anode iodine cathode side. First, EMIM + embedded lean‐water inner Helmholtz plane (IHP) inert solvation sheath modulated OAc − effectively repels H 2 O molecules away from surface. preferential adsorption metal...
Metal anodes hold significant promise for next-generation energy storage, yet achieving highly reversible plating/stripping remains challenging due to dendrite formation and side reactions. Here we present a tailored electrolyte design surpass 99.9% Coulombic efficiency (CE) in zinc metal by co-engineering salts solvents address two critical factors: plating morphology the anode-electrolyte interface. By integrating dual-salt approach organic co-solvent design, these issues can be...
Abstract The electrocatalytic N 2 reduction reaction (NRR) to produce ammonia is an attractive but highly challenging approach, due the extreme inertness of molecules and significantly lower concentration compared surrounding water molecules. Herein, NbO nanoparticles are demonstrated as efficient NRR electrocatalyst with improved electrochemical performances.

Identifying highly selective catalysts and accurately measuring NH3 yield without false-positives from contaminations remain two challenges in electrochemical nitrogen reduction reaction (NRR). Here, we report N-defective carbon nitride grown on paper (CN/C) as a electrocatalyst. The was determined reliably by the slope of mNH3-time plot rather than averaging accumulated amount over time. Results showed as-synthesized CN/C600 (synthesized at 600 °C) with higher density C=N-C N2C vacancies...
Abstract Aqueous zinc‐iodine battery (AZIB) has the advantage of low cost and high specific capacity but suffer from soluble polyiodides shuttling sluggish redox kinetics. Herein, these two limitations are addressed by employing a cathode additive (zirconium hydrogen phosphate, denoted as EI‐ZrP) which provides dual functions: an agent for polyiodide confinement, abundant channels zinc ion transport. An enlarged crystalline interlayer (from typical 7.5 to 18.3 Å) EI‐ZrP significantly...
Large language models (LLMs) have a wealth of knowledge that allows them to excel in various Natural Language Processing (NLP) tasks. Current research focuses on enhancing their performance within existing knowledge. Despite vast knowledge, LLMs are still limited by the amount information they can accommodate and comprehend. Therefore, ability understand own limitations unknows, referred as self-knowledge, is paramount importance. This study aims evaluate LLMs' self-knowledge assessing...
