制备方法与用途

简介 大气中约含有40万亿吨气体,其中氮气占78%,它微溶于水和酒精,是不可燃的,并被认为是一种窒息性气体。尽管氮被认为是惰性的,但它能形成一些非常活跃的化合物。氮气可用作稀释剂,控制自然燃烧和呼吸速率,在高氧浓度下会加速这些过程。在生命活动中,它是必不可少的,其化合物可用于食物或肥料。
用途 氮气(15-N2)是氮气的一种同位素气体,常用于核磁共振、生物同位素标记以及蛋白质大分子结构的研究。

    Single‐Atom or Dual‐Atom in TiO2Nanosheet: Which is the Better Choice for Electrocatalytic Urea Synthesis?
    摘要:
    Abstract

    As rising star materials, single‐atom and dual‐atom catalysts have been widely reported in the electro‐catalysis area. To answer the key question: single‐atom and dual‐atom catalysts, which is better for electrocatalytic urea synthesis? we design two types of catalysts via a vacancy‐anchorage strategy: single‐atom Pd1−TiO2and dual‐atom Pd1Cu1−TiO2nanosheets. An ultrahigh urea activity of 166.67 molurea molPd−1 h1with the corresponding 22.54 % Faradaic efficiency at −0.5 V vs. reversible hydrogen electrode (RHE) is achieved over Pd1Cu1−TiO2, which is much higher than that of Pd1−TiO2. Various characterization including an in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and theoretical calculations demonstrate that dual‐atom Pd1Cu1site in Pd1Cu1−TiO2is more favorable for producing urea, which experiences a C−N coupling pathway with a lower energy barrier compared with Pd1in Pd1−TiO2.

    revealed that the competition between the back-donation from metal to dinitrogen and that from metal to ligand was affected by P–N–P bite angle and the dihedral angle of N-substituent of ligand. In order to examine the reactivity with respect to conversion of dinitrogen to ammonia, protonation and trimethylsilylation reactions of the coordinated dinitrogens were carried out for 2R.

    A highly efficient and versatile chemical cycle has been developed for the production of isocyanates through the molecular fixation of N2, CO2 and R3ECl (E=C, Si, and Ge). Key steps include a ‘one‐pot’ photolytic NN bond cleavage of a Group 6 dinuclear dinitrogen complex with in situ trapping by R3ECl to provide a metal terminal imido complex that can engage in simultaneous nitrene‐group transfer

    The coupling of electron‐ and protontransfer steps provides a general concept to control the driving force of redox reactions. N2 splitting of a molybdenum dinitrogen complex into nitrides coupled to a reaction with Brønsted acid is reported. Remarkably, our spectroscopic, kinetic, and computational mechanistic analysis attributes N−N bond cleavage to protonation in the periphery of an amide pincer
