Noble metal-based surface chemistry is a well-practiced domain on interest in catalysis. A newborn in mussel-inspired coating based on catecholic chemistry, poly(norepinephrine) (PNE), has been synthesized via cyclization polymerization technique over MnO 2 nanosheets. The physisorped PNE macromolecular chains over MnO 2 nanosheets act as green reducing agent for silver ions resulting in arresting the quasi-spherical silver nanoparticles distributed over the MnO 2-PNE assembly. The catalytic activity was performed against nitroaryl molecules which evidenced fast reduction with pseudo-first-order kinetics. The superiority which lies in this work is their facile preparation, high surface area due to sheet-like morphology, and fast catalytic reduction. These practical observations spread its window as nanocatalyst toward environmental remediation of hazardous nitroaryl compounds.

“…Metal–organic frameworks (MOF)s have been regarded as an ideal template/precursor for fabricating various nanocatalysts for catalytic reactions because of their tunable metal ions and polyfunctional organic ligands . Among various hydrogenation products, functionalized arylamines are the significant feedstocks for production of various pharmaceuticals, fine chemicals, and polymers. − Numerous studies of the reduction of nitroarenes to arylamines have revealed that employing molecular hydrogen (H 2 ) as the reductant is a promising way from economic and renewable viewpoints. − To date, among various hydrogenation catalysts, the supported catalysts exhibited good performance for hydrogenation reactions because the generated hydride could be efficiently stabilized and surface hydrogen spillover resulting from the formed interfacial structure could be inhibited. − …”

Metal−organic framework (MOF)-templated strategy is an effective route to fabricate nanocatalysts for heterogeneous catalytic reactions. In this work, a coordinationevaporation-calcination (CEC) strategy was developed to synthesize a ceria (CeO 2 )-supported Ni−Co alloy catalyst (termed Ni− Co/CeO 2 -CEC) from a quaternary MOF (named as Ni−Co−Zn− Ce−H 2 salen) designed by metalloligand strategy. The Ni−Co− Zn−Ce−H 2 salen and its cross-bridging Zn 2+ ions simultaneously acted as self-sacrificing templates because of their thermal decomposition and evaporation at high-temperature (800 °C) pyrolysis process, which could facilitate the formation of bimetallic Ni−Co alloy with high dispersity and strengthen the Ni−Co− CeO 2 interaction, as well as the high concentration of oxygen vacancy defects. These unique advantages endow Ni−Co/CeO 2 -CEC with outstanding catalytic activity and yield for the hydrogenation process compared with Ni−Co/CeO 2 −CC (prepared by coordination-calcination method) and Ni−Co/CeO 2 -IWI (prepared by incipient wetness impregnation) catalysts, as well as good recyclability. We anticipate that this CEC strategy designed by Ce−H 2 salen metalloligand will provide a way for synthesizing other efficient and low-cost supported catalysts for catalytic reactions.

“…Nanostructured metals with unique surfaces [1] were widely used in a variety of fields, such as surface modification [2], ultra-hydrophobic layers [3][4][5], supercapacitors [6], microelectronic interconnection [7], nanoprobes [8], solar cells [9], gas sensors [10,11], catalysts [12][13][14][15][16][17][18][19], mechanical polishing slurries [20], diamond wheels [21], nanoscale precision surfaces [22,23]. As a result, many preparation techniques of nanostructured metal surfaces had been proposed, including hydrothermal method [10,11], sol-gel method [24], template method [25], chemical vapor deposition method [26], chemical reduction method [27], and microemulsion method [28].…”

“…Furthermore, nickel, as a good ferromagnetic conductive metal, had the advantages of low price, wide use, and excellent corrosion resistance [34]. Ni nanocones obtained by electrodeposition with solution containing NH 4 Cl had important applications in gassensitive sensors [10,11], ultra-hydrophobic surfaces [3][4][5], and catalysts [12][13][14][15][16][17][18][19].…”

Dialectical Observation of Controllable Electrodeposited Ni Nanocones: the Unification of Local Disorder and Overall Order

et al. 2020

Dense and ordered Ni nanocones with regular spiral textures had been successfully synthesized via a simple and inexpensive electrodeposition process in the solution containing sodium chloride (NaCl), nickel chloride hexahydrate (NiCl 2 •6H 2 O), and boric acid (H 3 BO 3). After analyzing the microstructure, a more optimized possible growth mechanism of Ni nanocones was proposed, in which the growth process was divided into local and global aspects, named multi-dimensional growth mechanism of global order and local disorder. In an area small enough, any subtle state changes would cause disorder of Ni atom arrangement, which made the local microstructure appear disordered, but from a macro perspective, the difference between two adjacent disorders caused by different statuses was too small to be well reflected, only when the difference in state was large enough can the change be observed in the macroscopic appearance, so the global was orderly. Meanwhile, we found that the microstructure of Ni nanocones would be controlled in the electrodeposition solution by adjusting the experiment parameters such as the concentration of NaCl, NiCl 2 •6H 2 O, and H 3 BO 3 , which indirectly determined the microstructure in a large extent via controlling the generation of intermediate products and the pH.
