Several monometallic {LO(i)}M complexes of lithium (M = Li; i = 1 (1), 2 (2), 3 (3)) or potassium (M = K, i = 3 (4)) and the heteroleptic bimetallic lithium complex {LO(3)}Li·LiN(SiMe2H)2 (5), all supported by monoanionic aminoether-phenolate {LO(i)}(-) (i = 1-3) ligands, have been synthesized and structurally characterized. A large range of coordination motifs is represented in the solid state...

Pt/Al2O3 and bimetallic PtPd/Al2O3 catalysts were prepared via supercritical deposition method using carbon dioxide. The effects of Pt loading Pd addition to on particle size, size distribution (PSD) activity for NO C3H6 oxidation C3H6-selective catalytic reduction (C3H6-SCR) investigated. with loadings 0.6, 1.2 2.1 wt% a catalyst was total metal 1.4 Pt:Pd molar ratio 1.3:1.

Abstract. Production of hyperpolarized catalyst-free gases and liquids by heterogeneous hydrogenation with parahydrogen can be useful for various technical as well biomedical applications, including in vivo studies, investigations mechanisms industrially important catalytic processes, enrichment nuclear spin isomers polyatomic gases, more. In this regard, the wide systematic search catalysts ef...

Impregnation is the most commonly used approach to prepare supported metal catalysts in industry. However, this method suffers from formation of large particles with uneven dispersion, poor thermal stability, and thus unsatisfied catalytic performance. Here, we demonstrate that self-pillared MFI zeolite (silicalite-1 ZSM-5) nanosheets larger surface area abundant Si-OH groups are ideal supports...

Abstract A high-efficient and stable catalyst is highly desired to catalyze ozone for refractory organic pollutants removal. In this work, Mn-Ce bimetallic oxide loaded CNT@Fe 3 C (Mn 0.7 Ce 0.3 O x /CNT@Fe C) was synthesized with Mn as the active component magnetic support. The catalytic performance of towards ozonation evaluated. TOC removal efficiency phenol degradation after 45 min reaction...

A finite element (FE) analysis of a CT25 specimen has been achieved for three configurations of a welded structure : monometallic (base metal), bimetallic (base metal and weld metal) and trimetallic (BM+WM+HAZ). Using the RICE-TRACEY model, a void growth parameter R& has been computed for each case. The evolution of this parameter indicates clearly that the bimetallic specimen is the most h d w...

Monometallic complexes based on 3d transition metal ions in certain axial coordination environments can exhibit appreciably enhanced magnetic anisotropy, important for memory applications, due to stabilisation of an unquenched orbital moment. For high-spin trigonal bipyramidal Ni(ii), if competing structural distortions can be minimised, this may result in an axial anisotropy that is at least a...

Most of the world's hydrogen supply is currently obtained by reforming hydrocarbons. 'Reformate' hydrogen contains significant quantities of CO that poison current hydrogen fuel-cell devices. Catalysts are needed to remove CO from hydrogen through selective oxidation. Here, we report first-principles-guided synthesis of a nanoparticle catalyst comprising a Ru core covered with an approximately ...

In a combination of generation and storage hydrogen gas, both formic acid (FA) acetic (AA) have been notified as efficient carriers. This study was conducted to synthesize the monometallic catalysts namely palladium (Pd), copper (Cu), zinc (Zn) on graphitic-carbon nitride (g-C3N4) potential these in FA mixed (FA)-acetic decomposition reaction. Several parameters studied this work such type acti...
