Synthesis of cationic molybdenum-cobalt heterometallic clusters protected against hydrolysis by macrocyclic triazacyclononane complexes

03-Jul-2018 | Sugiarto .; Tomoko Tagami; Keisuke Kawamoto; Yoshihito Hayashi, Dalton Transactions, 2018

Four kinds of cobalt-polyoxomolybdenum clusters were synthesized by a combination of polyoxomolybdates and a Co-tacn (tacn = 1,4,7-triazacyclononane) complex. The heterometallic polynuclear clusters were obtained by the reaction of Na2MoO4 and [Co(tacn)(H2O)3](CF3SO3)3∙H2O in aqueous solution. ...

On the possibility of an Eley–Rideal mechanism for ammonia synthesis on Mn6N5+x (x = 1)-(111) surfaces

03-Jul-2018 | Constantinos D. Zeinalipour-Yazdi, Physical Chemistry Chemical Physics, 2018

Recently we reported an Eley–Rideal/Mars–van Krevelen mechanism for ammonia synthesis on cobalt molybdenum nitride (Co3Mo3N). In this mechanism hydrogenation of activated dinitrogen occurs directly from the gas phase in a low barrier step forming a hydrazinylidene intermediate [[double bond, ...

Iron(II) and cobalt(II) complexes based on anionic phenanthroline-imidazolate ligands: reversible single-crystal-to-single-crystal transformations

03-Jul-2018 | Alexandre Abhervé; Samia Benmansour; Carlos J. Gomez Garcia; Narcis Avarvari, CrystEngComm, 2018

A series of low-spin FeII and CoII complexes based on phenanthroline-imidazolate (PIMP) ligands is reported. The FeII complex (H9O4)[Fe(PIMP)3]·(C4H10O)2(H2O) (1a) shows reversible crystalline phase transformations to afford two new phases (H9O4)[Fe(PIMP)3]·(H2O) (1b) and ...

Synthesis of efficient Co and N co-doped carbon catalysts with high surface areas for selective oxidation of ethylbenzene

03-Jul-2018 | Yuan Li; Shanshan Jie; Kun Li; Zhigang Liu, New Journal of Chemistry, 2018

In this manuscript, Co and N co-doped carbon catalysts with high surface areas were prepared via the pyrolysis of cobalt nitrate and 1,10-phenanthroline monohydrate, using Mg(OH)2 as a pore former, followed by acid etching. Techniques such as BET analysis, TEM, HRTEM, XPS, and Raman and XRD ...

Cobalt entrenched N-, O-, and S-tridoped carbons as efficient multifunctional sustainable catalysts for base-free selective oxidative esterification of alcohols

26-Jun-2018 | Devaki Nandan; Giorgio Zoppellaro; Ivo Medrik; Claudia Aparicio; Pawan Kumar; Martin Petr; Ondrej Tomanec; Manoj B G ..., Green Chemistry, 2018

We report the synthesis of sustainable and reusable non-noble transition-metal (cobalt) nanocatalysts containing N-, O-, and S-tridoped carbon nanotubes (Co@NOSC) composites. The inexpensive and benign carrageenan served as carbon, oxygen, and sulfur source, while urea supplied the nitrogen ...

B,N,S tri-doped Reduced Graphite Oxide-Cobalt Oxide Composite: A Bifunctional Electrocatalyst for Enhanced Oxygen Reduction and Oxygen Evolution Reaction

26-Jun-2018 | Sagar Ingavale; Indrajit Patil; Haridas Babaso Parse; Niranjan S Ramgir; Bhalchandra Anand Kakade; Anita Swami, New Journal of Chemistry, 2018

In the present study, we followed a unique approach to synthesize a nanocomposite of B,N,S tri-doped graphite oxide and cobalt oxide. Initially, B,N,S tri-doped carbon quantum dots were prepared by hydrothermal method using boric acid and L-cysteine as precursors, which were further immobilized ...
