Single‐Atom Bi Alloyed Pd Metallene for Nitrate Electroreduction to Ammonia

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(12)

Published: Jan. 15, 2023

Abstract Electrochemical reduction of nitrate to ammonia (NO 3 RR) holds a great promise for attaining both NH electrosynthesis and wastewater purification. Herein, single‐atom Bi alloyed Pd metallene (Bi 1 Pd) is reported as highly effective NO RR catalyst, showing near 100% ‐Faradaic efficiency with the corresponding yield 33.8 mg h −1 cm −2 at −0.6 V versus RHE, surpassing those almost all ever catalysts. In‐depth theoretical operando spectroscopic investigations unveil that electronically couples its neighboring atoms synergistically activate − destabilize *NO on Pd, leading reduced energy barrier potential‐determining step (*NO→*NOH) enhanced protonation energetics ‐to‐NH pathway.

Single‐atomic Co‐B ₂ N ₂ sites anchored on carbon nanotube arrays promote lithium polysulfide conversion in lithium–sulfur batteries

Carbon Energy, Journal Year: 2023, Volume and Issue: 5(11)

Published: March 23, 2023

Abstract Due to low cost, high capacity, and energy density, lithium–sulfur (Li–S) batteries have attracted much attention; however, their cycling performance was largely limited by the poor redox kinetics sulfur utilization. Herein, predicted density functional theory calculations, single‐atomic Co‐B 2 N site‐imbedded boron nitrogen co‐doped carbon nanotubes (SA‐Co/BNC) were designed accomplish loading, fast kinetic, long service period Li–S batteries. Experiments proved that atomic sites can effectively catalyze lithium polysulfide conversion. Therefore, electrodes delivered a specific capacity of 1106 mAh g −1 at 0.2 C after 100 cycles exhibited an outstanding cycle over 1000 1 with decay rate 0.032% per cycle. Our study offers new strategy couple combined effect nanocarriers catalysts in novel coordination environments for high‐performance
