PdNPs\/\u03b1-Al2O3 catalyst was prepared with monodispersed PdNPs and showed better catalytic performance than Pd\/\u03b1-Al2O3 catalyst prepared by the incipient wetness impregnation method using Pd(NO3)2 as a precursor. The catalysts were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRD) and inductively coupled plasma mass spectrometry (ICP-MS). It was found that monodispersed PdNPs were spherical or elliptical nanoparticles with exposed (111) and (100) facets, and the PdNPs\/\u03b1-Al2O3 catalyst showed a more concentrated distribution of Pd particles on the surface of \u03b1-Al2O3 support than the Pd\/\u03b1-Al2O3 catalyst. The preparation method achieved the highly dispersed PdNPs\/\u03b1-Al2O3 catalyst with smaller Pd particle size and decreased the aggregation of Pd active sites, which was responsible for higher acetylene conversion and ethylene selectivity.<\/jats:p>","DOI":"10.3390\/catal7050128","type":"journal-article","created":{"date-parts":[[2017,4,28]],"date-time":"2017-04-28T11:57:04Z","timestamp":1493380624000},"page":"128","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Highly Dispersed PdNPs\/\u03b1-Al2O3 Catalyst for the Selective Hydrogenation of Acetylene Prepared with Monodispersed Pd Nanoparticles"],"prefix":"10.3390","volume":"7","author":[{"given":"Huoli","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Polytechnic University, Jiaozuo 454000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youchao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Polytechnic University, Jiaozuo 454000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6671-4661","authenticated-orcid":false,"given":"Yan","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory Cultivation Base for Gas Geology and Gas Control, Henan Polytechnic University, Jiaozuo 454000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3570-5185","authenticated-orcid":false,"given":"Jianliang","family":"Cao","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Polytechnic University, Jiaozuo 454000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Kang","sequence":"additional","affiliation":[{"name":"Sinopec Beijing Research Institute of Chemical Industry, Beijing 100013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingjie","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Polytechnic University, Jiaozuo 454000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingjie","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Henan Polytechnic University, Jiaozuo 454000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,4,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"91","DOI":"10.1080\/01614940500364909","article-title":"Selective hydrogenation of ethyne in ethane-rich streams on palladium catalysts, Part 1: Effect of changes to the catalyst during reaction","volume":"48","author":"Bond","year":"2006","journal-title":"Catal.
