  A phosphine complex of copper (I) bromide as single-source precursor for the aerosol-assisted chemical vapour deposition of phosphide

  摘要：

  A new homobimetallic complex [Cu-2(tpp)(2)(dppm)Br-2] (1) of copper(I) bromide with triphenylphosphine (tpp) and bis-diphenylphosphinomethane (dppm) has been synthesized and charaterized by m.p., elemental analysis, FT-IR, H-1 NMR, mass spectrometry, thermal studies and single crystal X-ray analysis. The solid-state molecular structure of 1, belonging to the monoclinic crystal system with space group P2(1)/n, describes it as a neutral dinuclear species in which two copper atoms are bridged together through two bromides and a dppm ligand and each copper atom possesses a distorted tetrahedral geometry. Complex 1 was studied as a single-source precursor for the fabrication of phase pure thin films of Cu3P by aerosol-assisted chemical vapour deposition. The films have been characterized by PXRD, SEM and ED-XRF analyses and found to exhibit the particles size range 200-400 nm with high purity and surface uniformity. (C) 2009 Elsevier B.V.

  通过亲氧表面修饰调控Cu 3 P的电化学析氢活性。

  摘要：

  碱性介质中的氢释放反应可通过将铂族金属与嗜氧性金属改性来促进。在此，首先将富含稀土的金属转化为磷化铜Cu 3 P，并通过短而简单的方法对其进行电化学活化，以产生氧化的电活性表面。与原始Cu 3 P催化剂相比，电化学活化的Cu 3 P催化剂在碱性介质中在10 mA / cm 2下显示出155 mV的HER过电势（比Cu 3 P催化剂降低了90 mV ），并具有24小时的稳定性。XRD，XPS和EDS表明，氧化仅发生在Cu 3的表面P表示同时存在磷化铜和氧化物。

  Non‐noble metal‐based hydrogenation catalysts have limited practical applications because they exhibit low activity, require harsh reaction conditions, and are unstable in air. To overcome these limitations, herein we propose the alloying of non‐noble metal nanoparticles with phosphorus as a promising strategy for developing smart catalysts that exhibit both excellent activity and air stability. We synthesized

  非贵金属基加氢催化剂的实际应用受到限制，因为它们显示出低活性，要求苛刻的反应条件并且在空气中不稳定。为了克服这些局限性，我们在本文中提出将非贵金属纳米粒子与磷合金化，作为开发具有出色活性和空气稳定性的智能催化剂的一种有前途的策略。我们合成了具有不饱和Ni活性位点的新型磷化镍纳米合金（nano-Ni 2 P）。与传统的空气不稳定的非贵金属催化剂不同，纳米Ni 2P在空气中保持其金属性质，并在水中以极高的收率表现出高活性，可将各种带有极性官能团（如醛，酮，腈和硝基芳烃）的底物氢化成所需的产物。此外，所用的纳米Ni 2 P催化剂易于在空气中处理，无需进行预处理即可重复使用，从而为一般的加氢反应提供了简单，清洁的催化剂体系。

  Oriented attachments have been extensively studied as an effective method for the formation of large crystals from seed nanocrystals. However, this has been limited mostly to seeds of single-phase materials. In contrast, in this work, oriented attachment of two types of nanocrystals with differences in size, shape, phase, and physical as well as chemical properties is reported. Noble metal (Au) nanoparticles were observed to be crystallographically oriented along the preferred direction on semiconducting Cu3P disks and further annealed to obtain intriguing ring-on-disk metal–semiconductor heterostructures. This was triggered using PH3 gas, which bridged the metal Au particles and Cu3P disk. The phosphine chemistry underlying the formation of such heterostructures was elucidated by carrying out several control reactions and analyzing the intermediate products. Because of their optically active nature and dual plasmon effects, these heterostructures were applied as photocatalyst for hydrogen evolution from water, and their efficiency was evaluated.

  Copper nitride (Cu3N) was used as a heterogeneous catalyst for the hydroxylation of aryl halides under ligand-free conditions. The cubic Cu3N nanoparticles showed high catalytic activity, comparable to those of conventional Cu catalysts with nitrogen ligands, demonstrating that the nitrogen atoms in Cu3N act as functional ligands that promote hydroxylation.
