Understanding Degradation Mechanisms in Water‐In‐Salt Electrolyte. Part 2: Impact of the Electrochemical Parameters on the Cycling Behavior of LiFePO4 versus TiS2

open access: yesBatteries &Supercaps, EarlyView.
Cycling water‐in‐salt batteries involves complex degradation processes that require multiprobe analysis. Using online electrochemical mass spectrometry (OEMS), postmortem X‐ray photoemission spectroscopy (XPS) (including hard‐XPS), and scanning electron microscopy (SEM), the degradation mechanisms are examined in composite electrodes (TiS2 and LiFePO4)

Asymmetric‐Coordinated Indium Single Atoms for Highly Selective Photocatalytic CO2 Reduction

open access: yesCarbon Energy, EarlyView.
This work develops an indium single‐atom photocatalyst (In‐NTO) featuring unique Inδ⁺–N3O2 coordination sites for highly selective CO2 photoreduction. The specific atomic interface steers the reaction pathway exclusively toward CO (95.9% selectivity) by lowering the overall energy barrier and converting the critical *CO protonation step from ...
