One-step hydrothermal synthesis and gas sensing property of ZnSnO3 microparticles

Simple Solid‐State Chemical Synthesis of ZnSnO3 Nanocubes and Their Application as Gas Sensors

“…Reported results show good sensitivity over simple oxides and can improve the selectivity of sensing materials to different reducing and oxidizing gases. [10][11][12][13] Current studies on CMO materials have been focused on zero-dimensional microparticles or nanoparticles, and little work has been devoted to 1D nanomaterials, which can be synthesized by various well-established techniques, including a chemical solution route, template synthesis, chemical vapor deposition, thermal evaporation, and a template-induced, citrate-based, sol-gel process. [14][15][16][17][18][19][20] To date, we have found nothing in the literature on the synthesis of cubic CMO nanomaterials.…”

Phase transformation behavior of zinc metastannates obtained by aqueous precipitation at different temperatures

“…(aq) and Sn 4? (aq) at high temperatures in an autoclave (200°C) leads to the formation of polydispersed particles of ZnSnO 3 with a high probability of the obtaining mixed phases [22,23]. Low temperature synthesis is preferable for controlled precipitation of monodispersed ZnSnO 3 particles.…”

Microstructure and Gas-Sensing Property of Titania-Added ZnSnO<SUB>3</SUB>

“…[11][12][13] Moreover, its gas-sensing character can be improved significantly via the addition of not only noble metals, for example, Pd and Pt, but also more importantly, metal oxide like SnO 2 , ZnO, and TiO 2 . [14][15][16][17] Although it has been known that these cheap oxide additives are capable of altering or improving the gassensing functionality of ZnSnO 3 , little is known about how the loading methods affect the properties, which if well understood, could provide a guideline for mass production on an industrial level. In general, a detailed knowledge on such effect requires a bridging study of microstructures of ZnSnO 3 -based sensors fabricated by different loading ways to the gas-sensing properties, and this has so far been lacking.…”
