The effect of different amounts (1.25%, 2.5% and 5%) of Pd loading has been investigated. The as prepared materials were deposited on Pt microcoils using a drop-coating method, as a way of developing pellistors operated using a Wheatstone bridge configuration. By spanning the operating temperature range between 300 \u00b0C and 550 \u00b0C, we established the linearity region as well as the maximum sensitivity towards 4900 ppm of CH4. By making use of the sigmoid dependence of the output voltage signal from the Wheatstone bridge, the gas surface reaction and diffusion phenomena have been decoupled. The pellistor with 5% Pd deposited on CeOx-MnOx\/La-Al2O3 exhibited the highest selective-sensitivity in the benefit of CH4 detection against threshold limits of carbon monoxide (CO), sulfur dioxide (SO2) and hydrogen sulfide (H2S). Accordingly, adjusting the percent of Pd makes the preparation strategies of pellistors good candidates towards CH4 detection.<\/jats:p>","DOI":"10.3390\/ma13214888","type":"journal-article","created":{"date-parts":[[2020,10,30]],"date-time":"2020-10-30T21:34:47Z","timestamp":1604093687000},"page":"4888","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Methane Combustion Using Pd Deposited on CeOx-MnOx\/La-Al2O3 Pellistors"],"prefix":"10.3390","volume":"13","author":[{"given":"Ovidiu G.","family":"Florea","sequence":"first","affiliation":[{"name":"Laboratory of Atomic Structures and Defects in Advanced Materials, National Institute of Materials Physics, Atomistilor 405A, 077125 Magurele, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adelina","family":"St\u0103noiu","sequence":"additional","affiliation":[{"name":"Laboratory of Atomic Structures and Defects in Advanced Materials, National Institute of Materials Physics, Atomistilor 405A, 077125 Magurele, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marin","family":"Gheorghe","sequence":"additional","affiliation":[{"name":"NANOM-MEMS SRL, G.
