The complexity of heterogeneous metal catalysts makes it challenging to gain insights into their catalytic mechanisms. Thus, there exists a huge gap between catalysis and organometallic catalysis. With the success in preparation highly robust atomically precise nanocluster (i.e., [Au16(NHC-1)5(PA)3Br2]3+ [Au17(NHC-1)4(PA)4Br4]+, where NHC-1 is bidentate NHC ligand, PA phenylacetylide) with surface motifs anchored on metallic core, we demonstrate this work how core works synergistically...
Abstract Semitransparent perovskite solar cells (st‐PSCs) have received remarkable interest in recent years because of their great potential applications for window, tandem cells, and flexible photovoltaics. However, all reported st‐PSCs require expensive transparent conducting oxides (TCOs) or metal‐based thin films made by vacuum deposition, which is not cost effective large‐scale fabrication: the TCOs estimated to occupy ≈75% manufacturing PSCs. To address this critical challenge, study...
Abstract Deciphering the molecular pictures of multi‐component and non‐periodic organic‐inorganic interlayer is a grand technical challenge. Here we show that atomic arrangement hybrid surface ligands on metal nanoparticles can be precisely quantified through comprehensive characterization novel gold cluster, Au 44 ( i Pr 2 ‐bimy) 9 (PA) 6 Br 8 1 ), which features three types ligands, namely, carbene (1,3‐diisopropylbenzimidazolin‐2‐ylidene, ‐bimy), alkynyl (phenylacetylide, PA), halide...
Copper nanostructures represent an important class of materials in CO2 electrocatalytic reduction (CO2ER) reactions, but deciphering their molecular structures, especially those with multiple and irregular organic–inorganic interfaces, remains a grand challenge. Through comprehensive characterization 26-nuclei copper nanocluster [Cu26(DPPE)3(CF3CO2)8(CH3O)2(tBuC≡C)4H11]+ (DPPE is 1,2-bis(diphenylphosphino)ethane), which stabilized by quintuple ligand shells phosphine, carboxylic acid,...
A multifunctional molecule at interface was explored to inhibit phase separation and passivate defects, producing perovskite solar cells with efficiencies of 21.82% (0.05 cm 2 ) 18.05% (1.92 1.67 eV bandgap excellent stability.
Several recent studies have demonstrated the great promise of ligand-protected atomically precise copper nanoclusters in driving various chemical transformation processes. The insights into key factors controlling catalytic performance clusters at molecular level are highly desirable but difficult to gain. Herein, we report synthesis and comprehensive characterization two novel Cu20 nanoclusters, with formulae Se@Cu20(PhSe)12(PPh3)2(C6H5COO)6 (Cu20-1) Se@Cu20(PhSe)12(PPh3)2(CF3COO)6...
Abstract A stable ZnTe@Cs 3 Sb 2 I 9 catalyst with 3D/2D‐hollow‐composite structure is constructed for CO photocatalytic reduction via the in situ growth of Cs nanosheets on hollow ZnTe microspheres using lattice matching. The formed Tellurium‐Antimony (Te─Sb) bonds improved poor contact at heterojunction interface, effectively promoted charge separation, and successfully suppressed photocorrosion. unique core‐shell not only strengthens light absorption but also improves adsorption capacity....
Hydrides in metal complexes or nanoclusters are typically viewed as electron-withdrawing. Several recent reports have demonstrated the emergence of “electron-donating” hydrides tailoring structure, electronic and reactivity nanoclusters. However, number such included each cluster kernel is limited to one two. There even no structure model, neither theoretical nor experimental, for encapsulating a third electron-donating hydride into entity. Here, we present structurally precise superatomic...
Abstract Copper-hydrides have been intensively studied for a long time due to their utilization in variety of technologically important chemical transformations. Nevertheless, poor stability the species severely hinders its isolation, storage and operation, which is worse nano-sized ones. We report here an unprecedented strategy access ultrastable copper-hydride nanoclusters (NCs), namely, using bidentate N-heterocyclic carbenes as stabilizing ligands addition thiolates. In this work, simple...
Atomically precise copper nanoclusters have recently attracted tremendous attention, as they often exhibit structures and properties distinct to their gold silver counterparts. Although considerable progress has been made in the preparation structure determination of nanoclusters, introduction those newly created materials more underlying areas such nonlinear optics is its infancy. Herein, we report a new class Cu50 exhibiting tunable optical limiting effect. The facile prototype reported...
Manipulating the interfacial/surface structure of ligand-stabilized atomically precise metal nanoclusters (NCs) is one central tasks in nanoscience because surface motifs are directly related to key properties nanomaterials. Although great progress has been made engineering gold and silver nanoclusters, parallel studies on lighter copper analogues hitherto remain unexplored. In this work, we report design, synthesis, a new class featuring virtually identical kernels but different motifs. The...
Novel copper-hydride nanoclusters of [Cu 14 ( t BuS) 3 (PPh ) 7 H 10 ] + have been prepared. The cluster exhibits intrinsic chirality and helix assembling structures.
A full selectivity control over the catalytic hydrogenation of nitroaromatics leads to production six possible products, i.e., nitroso, hydroxylamine, azoxy, azo, hydrazo or aniline compounds, which has however not been achieved in field heterogeneous catalysis. Currently, there is no sufficient evidence support that with use metal catalysts would follow Haber's mechanistic scheme based on electrochemical reduction. We now demonstrate this work it fully into their all products using a single...
