Hematite α-Fe₂O₃ nanorods and laser-induced graphene for sustainable chemiresistive sensing of 1-butanol at room temperature.

ABSTRACT: Volatile organic compounds (VOCs) present in workplace and domestic settings present risks to human health, e.g., 1-butanol concentrations >100 ppm can cause central nervous system depression and respiratory/skin irritation. Traditional chemiresistive metal-oxide gas sensor platforms frequently rely on noble metal contact electrodes (Au,Pt) and high-temperature operation (200-600 °C), increasing cost and environmental footprint impacts. Consequently, there is an urgent need for sustainable and affordable materials for chemiresistive gas sensors that can operate at room temperature. Our approach combines hematite (α-Fe₂O₃) nanorods, synthesized via a low-impact co-precipitation method, with 3D porous laser-induced graphene (LIG) electrodes for room-temper
