Solids were characterized by thermogravimetric and differential thermal analysis (TG–DTA), X-ray diffraction (XRD), adsorption–desorption of N2 (BET surface), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). Sample tests of Pd-doped sensors showed much higher sensitivity than the undoped one revealing the promotion electronic effect of Pd2+ on the surface reaction. Among all samples, the sensor with 0.75 wt.% Pd presented the highest gas response at 300 °C in all gas tested concentrations, likely due to the highest BET surface, well-defined hematite crystalline structure and best surface contact over Pd surface via electronic mechanism.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengElsevier B.V.info:eu-repo/semantics/openAccessPd-doped α-Fe2O3Gas sensor-1LPG detection-1https://purl.org/pe-repo/ocde/ford#1.04.00-1Sensors based on porous Pd-doped hematite (α-Fe2O 3) for LPG detectioninfo:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/941oai:repositorio.concytec.gob.pe:20.500.12390/9412024-05-30 15:36:18.035http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="5adc594a-c525-47ec-942e-b3acd6538c8a"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Sensors based on porous Pd-doped hematite (α-Fe2O 3) for LPG detection</Title> <PublishedIn> <Publication> </Publication> </PublishedIn> <PublicationDate>2014</PublicationDate> <DOI>https://doi.org/10.1016/j.micromeso.2013.11.014</DOI> <SCP-Number>2-s2.0-84889803714</SCP-Number> <Authors> <Author> <DisplayName>Picasso G.</DisplayName> <Person id="rp02497" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Sun Kou M.R.</DisplayName> <Person id="rp01809" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Vargasmachuca O.</DisplayName> <Person id="rp02496" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Rojas J.</DisplayName> <Person id="rp01220" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Zavala C.</DisplayName> <Person id="rp01082" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Lopez A.</DisplayName> <Person id="rp02499" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Irusta S.</DisplayName> <Person id="rp02498" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Elsevier B.V.</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>Pd-doped α-Fe2O3</Keyword> <Keyword>Gas sensor</Keyword> <Keyword>LPG detection</Keyword> <Abstract>In this work, sensors based on nanoparticles of α-Fe2O3 doped with different amounts of Pd ranging from 0.1 to 1.0 wt.% were prepared by coprecipitation for liquefied petroleum gas (LPG) detection.
