Advancing Humidity‐Resistant Triboelectric Nanogenerators Through MoS₂‐Encapsulated SiO₂ Nanoparticles for Self‐Powered Gas Sensing Applications

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

Published: Jan. 24, 2025

Abstract In this study, the humidity‐resistant triboelectric nanogenerators (TENGs) utilizing MoS₂‐encapsulated SiO₂ nanoparticles (NPs), aimed at enhancing self‐powered gas sensing applications, are reported. The core‐shell structure, featuring a thin MoS₂ layer uniformly grown on SiO₂, addresses common humidity‐induced performance degradation. growth mechanism involves decomposition and sulfidation of molybdenum species, with selectively nucleating to form stable, hydrophobic shell. This effectively shields interface from water molecule penetration, thus stabilizing charge density significantly reducing decay, even under high humidity conditions. TENGs constructed these NPs exhibit exceptional durability, retaining more than 70% output over 25 h 99% relative (RH). Furthermore, fabricated TENG reliably powers sensor array, enabling accurate detection in extreme humidity. work demonstrates potential as robust, energy solutions for environmental monitoring wearable devices challenging
