Preparation and oxygen sensing properties of Ti ₃ O ₅ submicron rods

Abstract

Ti 3 O 5 submicron rods, typically 0.5-2 µm in length and 100-300 nm in diameter, have been successfully synthesised via a facile approach combined hydrothermal and carbothermal reduction route. H 3 TiO 5 nanofibres blended with nano-sized carbon black were first prepared by the direct hydrothermal processing, and then Ti 3 O 5 submicron rods could be obtained by sintering the prepared nanofibres at 1250°C for 3 h. The microstructure and formation of phases in the reduction process were investigated, respectively. In addition, the oxygen sensing properties of the synthesised materials were preliminarily investigated by gas-sensing measurement. The results indicated that the electrical conductivity of the Ti 3 O 5 submicron rods varied with the oxygen concentration, and the responses increased as the oxygen concentration increased at 200°C.

Long-term heat-storage materials based on λ-Ti3O5for green transformation (GX)

“…The vast potential of l-Ti 3 O 5 has attracted many researchers: various synthesis methods have been developed, [36][37][38][39][40][41][42][43][44][45][46][47][48][49] studies of phase transition mechanism have been reported, [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66] and novel functionalities are being explored. [67][68][69][70][71][72][73][74][75][76] Since l-Ti 3 O 5 is composed of readily available elements of titanium and oxygen, it offers harmless, sustainable, and economic features, which are advantageous in industrial applications.…”
