Stepwise construction of Ag₂₉ nanocluster-based hydrogen evolution electrocatalysts

Abstract

The step-by-step enhancement of electrocatalytic hydrogen evolution reaction efficiency based on an Ag29 cluster template was accomplished.

Recent advances in synthesis and properties of silver nanoclusters

“…Zhu and co-workers 109 systematically designed an electrocatalytic hydrogen evolution catalyst based on an Ag 29 cluster by core-alloying with Pt and grafting optimal Mn onto the cluster's surface. In the resulting catalyst, PtAg 28 -BTT-Mn(10), the Mn site exhibits a Δ G H * value of 0.18 eV, which is suitable for the hydrogen evolution reaction.…”

Polyoxometalate-mediated syntheses of three structurally new silver clusters

“…nanoclusters have attracted increasing attention from the scientific community due to their novel aesthetic structures, unique physicochemical properties and widespread application, [1][2][3][4][5][6] including their promising applications in various fields like catalysis, photochromism, chirality, biomedicine, and chemical sensing, etc. [7][8][9][10][11][12][13][14] The synthesis of Ag clusters is inextricably linked to the involvement of surface-protecting organic ligands, mainly thiolate, [15][16][17][18][19] phosphine, [20][21][22] alkynyl, [23][24][25] and amide ligands 26 or appropriate combination of these ligands, 27 which can offer more possibilities for the structure and properties of Ag clusters. In addition to the adjustable ligand type, the introduction of structure-directing agents like anionic templates has also largely contributed to the construction of high-nuclearity Ag clusters, and the anion-template syn-thetic strategy has become a popular route for making novel Ag clusters.…”

Assembly of anionic silver nanoclusters with controlled packing structures through site-specific ionic bridges

“…The [Ag 29 (BDT) 12 (TPP) 4 ] 3− (BDT: 1,3-benzenedithiol, TPP: triphenylphosphine) NC (Ag 29 NC) 32–37 is one of the most studied silver-based luminescent NCs. Its atomically precise structure was clearly disclosed by single crystal X-ray diffraction (SCXRD) analysis, 32 also implying its intrinsically chiral structure.…”

“…Its atomically precise structure was clearly disclosed by single crystal X-ray diffraction (SCXRD) analysis, 32 also implying its intrinsically chiral structure. 35 Some recent efforts have focused not only on enhancing the PL performance 34 but also extending the photo- 36 and electronic- 37 functional properties. The Ag 29 NC exists as a trianion species to follow the electron count rule of the superatom theory, 26 and its counter cations can be modified by choosing a reductant (M + BH 4 − ) or adding a salt.…”
