Small, Journal Year: 2024, Volume and Issue: 20(34)

Published: April 12, 2024

Abstract Transition metal chalcogenides (TMCs) are widely used in photocatalytic fields such as hydrogen evolution, nitrogen fixation, and pollutant degradation due to their suitable bandgaps, tunable electronic optical properties, strong reducing ability. The unique 2D malleability structure provides a pre‐designed platform for customizable structures. introduction of vacancy engineering makes up the shortcomings photocorrosion limited light response greatest support TMCs terms kinetics thermodynamics photocatalysis. This work reviews effect on performance based semiconductor TMCs. characteristics strategies summarized, development photocatalysis materials energy conversion, degradation, biological applications is reviewed. contribution vacancies range charge transfer also discussed from perspective manipulation. Vacancy not only controls optimizes TMCs, but improves transfer, surface properties. synergies between atomic doping, other vacancies, heterojunction composite techniques detail, followed by summary current trends potential expansion.

Designed Fabrication of SnO₂/In₂O₃/C Electrochemical Sensors for Coolant Leakage Detection in Energy Storage Systems

ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 17, 2025

The liquid cooling system for lithium iron phosphate battery modules usually faces the threat of coolant leakage, which would dramatically affect heat transfer performance, safety, and efficiency energy storage system. Herein, electrochemical sensing technology has been first employed to detect leakage. Specifically, ethanol is selected as additive reagent used main tested substance, sensors indirectly identify leakage by detecting leaked ethanol. In order overcome disadvantages pure SnO2 detection, including poor response, low gas selectivity, high operating temperature, microspherical-structured SnO2/In2O3/C composite designed synthesized using a tin-indium metal-organic framework (SnIn-MOF) precursor. fabricated sensor exhibits excellent gas-sensing performance. response could reach 30.1 at 280 °C, 1 mL with only 0.01% be detected sensor. Moreover, also satisfactory cycling repeatability stability. This outstanding performance attributed structural stability synergistic effects SnO2, In2O3, carbon. work innovatively proposed feasible method high-quality material detection in an system, great importance application potential field conversion.
