“…1 In this regard, metal chalcogenide nanomaterials [1][2][3] have attracted the attention of researchers increasingly due to their various applications in energy conversion, storage and electronics, 2-5 development of materials for semiconductors, [6][7][8] dye-sensitized solar cells, 9,10 magnesium-air batteries, 11 aerogel fabrication, 12 and catalysis. [13][14][15][16][17][18][19][20] Among different metal chalcogenides reported in literature, signicant work has been done in recent past on the exploration and development of binary phases of tellurides of various metals (excluding palladium), mainly due to their potential application 2 in memory devices, photovoltaic cells, thermoelectrics, biochemical applications, semiconductors with enhanced thermoelectric properties in nanocomposites, photothermal therapy, thin lms and nanomaterials and catalysis. 2,4,[18][19][20] Aer the discovery of easy methods of preparation 16,17,21 of binary phases of palladium selenide and their role in catalysis, 16,17 there has been an enormous increase during last ve years on the discovery of interesting applications of palladium selenides 3,9-14 in various elds including catalysis.…”
