Redox-enhanced hemilability of the tris(tert-butoxy)siloxy ligand at cerium

03-Jul-2018 | Jochen Friedrich; Yusen Qiao; Caecilia Maichle-moessmer; Eric J Schelter; Reiner Anwander, Dalton Transactions, 2018

The stabilizing effect of the tris(tert-butoxy)silyoxy ligand on cerium(IV) is revealed by electrochemical and computation methods as well as targeted redox chemistry. Ceric homoleptic complex Ce[OSi(OtBu)3]4 was obtained by the reaction of [Et4N]2[CeCl6] with NaOSi(OtBu)3 at ambient temperature ...

Ultra-fast precipitation of transient amorphous cerium oxalate in concentrated nitric acid media

29-May-2018 | Isaac Rodríguez-Ruiz; Sophie Charton; Dimitri Radajewski; Thomas Bizien; Sébastien Teychené, CrystEngComm, 2018

Amorphous cerium oxalate precipitation is here characterized and reported for the first time as a primary nucleating transient precursor for a more stable crystalline hydrated phase, at high supersaturations and in strong acid solutions. Preliminary results point out an initial binodal phase ...

Amorphous saturated cerium–tungsten–titanium oxide nanofiber catalysts for NOx selective catalytic reaction

29-May-2018 | Apiwat Dankeaw; Fabrizio Gualandris; Rafael Hubert Silva; Kion Norrman; Mads Gudik-Sørensen; Kent Kammer Hansen ..., New Journal of Chemistry, 2018

Herein for the first time, Ce0.184W0.07Ti0.748O2−δ nanofibers are prepared by electrospinning to serve as a catalyst in the selective catalytic reduction (SCR) process. The addition of cerium is proven to inhibit crystallization of TiO2, yielding an amorphous TiOx-based solid solution stable up ...

Unique and contrasting structures of homoleptic lanthanum(III) and cerium(III) 3,5-dimethylpyrazolates

24-May-2018 | Daniel Werner; Uwe Bayer; Nazli E. Rad; Peter C. Junk; Glen B. Deacon; Reiner Anwander, Dalton Transactions, 2018

Homoleptic [La(Me2pz)3]n (Me2pz = 3,5-dimethylpyrazolato) is a μ–η2:η5-Me2pz coordination polymer with 12-coordinate La atoms in an unusual η5:η5 Me2pz sandwich, whilst the cerium congener forms a molecular tetrametallic cage [Ce4(Me2pz)12] featuring six different Me2pz coordination modes.

Fabrication of ultralong ceria nanobelts via a coordination polymer precursor method

23-Jan-2018 | Yuan Li; Hong-Hong Zou; Zhiwei Qiao; Yuan-Yuan Liao; Lei Wang; Shengliang Zhong, New Journal of Chemistry, 2018

Ultralong cerium-based coordination polymer (Ce-CP) nanobelts have been prepared from benzene-1,3-dicarboxylic acid (1,3-H2BDC) and Ce(NO3)3 via a facile solvothemal method, employing cheap and non-toxic mixture of ethanol and water as solvent. The products were well characterized and analyzed. ...

Comprehensive Understanding of the Spatial Configurations of CeO2 in NiO for the Electrocatalytic Oxygen Evolution Reaction: Embedded or Surface‐Loaded

17-Jan-2018 | Wei Gao, Zhaoming Xia, Fangxian Cao, Johnny C. Ho, Zheng Jiang, Yongquan Qu, Advanced Functional Materials, 2018

Abstract Introducing cerium (Ce) species into electrocatalysts has been recently developed as an effective approach to improve their oxygen evolution reaction (OER) performance. Importantly, the spatial distribution of Ce species in the hosts can determine the availability of Ce species either ...
