Crystal structures and hydrogenation properties of palladium-rich compounds with elements from groups 12–16
Abstract
<jats:title>Abstract</jats:title><jats:p>We report on crystal structure data and hydrogenation properties of 24 palladium-rich intermetallic compounds with elements from groups 12–16 of the Periodic Table. Refined crystal structures based on X-ray powder diffraction data are presented for Pd<jats:sub>3</jats:sub>As (Fe<jats:sub>3</jats:sub>P type structure) and several members of the Pd<jats:sub>5</jats:sub>TlAs type structure family. Hydrogenation was studied<jats:italic>in situ</jats:italic>by differential scanning calorimetry (DSC) under 5.0 MPa hydrogen pressure up to 430 °C. Pd<jats:sub>0.75</jats:sub>Zn<jats:sub>0.25</jats:sub>, PdCd, PdHg, Pd<jats:sub>2</jats:sub>Sn, Pd5Pb3, Pd<jats:sub>13</jats:sub>Pb<jats:sub>9</jats:sub>, Pd<jats:sub>3</jats:sub>As, Pd<jats:sub>20</jats:sub>Sb<jats:sub>7</jats:sub>, Pd<jats:sub>8</jats:sub>Sb<jats:sub>3</jats:sub>, Pd<jats:sub>5</jats:sub>Sb<jats:sub>2</jats:sub>, PdSb, Pd<jats:sub>5</jats:sub>Bi<jats:sub>2</jats:sub>, Pd<jats:sub>17</jats:sub>Se<jats:sub>15</jats:sub>, Pd<jats:sub>4</jats:sub>Se, Pd<jats:sub>5</jats:sub>TlAs, Pd<jats:sub>5</jats:sub>CdSe, Pd<jats:sub>5</jats:sub>CdAs, Pd<jats:sub>5</jats:sub>HgSe, Pd<jats:sub>5</jats:sub>InAs, Pd<jats:sub>8</jats:sub>In<jats:sub>2</jats:sub>Se and Pd<jats:sub>3</jats:sub>Bi<jats:sub>2</jats:sub>Se<jats:sub>2</jats:sub>do not show any sign of hydrogen uptake according to DSC and X-ray diffraction. For Pd<jats:sub>3</jats:sub>Sn and Pd<jats:sub>3</jats:sub>Pb a significant hydrogen uptake with unit cell volume increases of 0.4 and 0.6 %, respectively, with a retained structure type of the parent intermetallic was observed. Hydrogenation of Pd<jats:sub>5</jats:sub>InSe yields Pd<jats:sub>3</jats:sub>InH<jats:sub>≈0.9</jats:sub>and a mixture of palladium selenides. Thermal analysis experiments in helium and in hydrogen atmosphere show that this is a multistep reaction with a decomposition of Pd<jats:sub>5</jats:sub>InSe to Pd<jats:sub>3</jats:sub>In and a liquid phase and subsequent hydrogenation of Pd<jats:sub>3</jats:sub>In.</jats:p>
