“…2 displays the micrographs of the as-synthesized nanomaterials, where various morphologies, termed as nano-teeth, −sheet, −flowers and micro-rice throughout the paper, were fabricated. The decrease in the temperature and increase in the ion concentration affected the growth rate of the nano-particulates, and this decreased the feature size as expected [53]. As can be seen from Fig.…”

“…To control the particle size and morphology of the nanomaterial, the hydrothermal solution variables were altered, such as pH, ion concentration, and the processing temperature (and time). The method was based upon the previous works discussed in literature for SrMoO 4 , which produced varying nano-particle morphologies [49][50][51][52][53] The general procedure includes the dissolution of 1.48 g of strontium nitrate (Sr(NO 3 ) 2 (99.0%,) and 1.23 g of ammonium molybdate (((NH 4 ) 6 ·Mo 7 O 24 )·4H 2 O, 99%, Alfa Aesar) into de-ionized (and de-carbonized) water in separate beakers. A clear solution was obtained after magnetic stirring the two solutions for 15 min.…”

a b s t r a c tThere is an increasing desire to control and monitor gas emissions from coal-fired power plants and other industrial systems. With this desire, there is a growing need for distributed gas sensors to monitor these emissions at high temperature ( > 600 • C), especially for pollutants such as SO 2 and H 2 S. The objective of this work was to investigate molybdenum and tungsten binary and ternary oxide thick films on a chemiresistive sensor platform for monitoring of gas sulfur species. The work evaluated the SO 2 sensitivity of WO 3 , MoO 3 , SrMoO 4 , NiMoO 4 , Sr 2 MgMoO 6-␦ (SMM), Sr 2 MgWO 6-␦ (SMW), NiWO 4 , and SrWO 4 compositions at 600-1000 • C. The SrMoO 4 composition at both the micro-and nano-particulate scale showed the most promise in sensitivity, stability and selectivity to SO 2 up to 1000 • C. Hydrothermallysynthesized nano-SrMoO 4 showed the highest sensor response with the R max values of −17.2, −50.2 and −40.5 upon exposure to a 20 min pulse of 2000 ppm of SO 2 at 600 • C, 800 • C and 1000 • C, respectively. Similar sensitivity trends were distinguished down to 1-5 min SO 2 pulses. The nano-SrMoO 4 showed low cross-selectivity to H 2 and CO. Finally, the nano-SrMoO 4 sensor was also tested with H 2 and coal syngas containing 5-100 ppm H 2 S, where high sensitivities were realized for both, but the sensing mechanism was altered in the latter (n-type to p-type semiconducting behavior). In order to better understand the sensing mechanism, extensive microstructural, electronic and chemical property characterizations were completed in this work.

“…Recently, the fabrication of hierarchical and complex nano-and microstructures has attracted increasing attention in searching for materials with novel properties and tailorable functions. It offers opportunities in seeking exciting new properties of materials, and is helpful for making functional nanodevices [5]. Up to now, various kinds of metal oxide [6][7][8][9] and sulfide [10,11] with controlled hierarchical and complex morphologies have been successfully fabricated.…”
