Abstract:

Metallic copper has been attracted attention as efficient catalyst for electrochemical CO2 reduction reaction (CO2RR). However, the activity of the catalyst with a single adsorption site is limited by the imbalance of the intermediate binding energy, so-called “scaling relationship”. [1] Therefore, it is crucial to break the scaling relationship between reaction intermediates in order to increase product selectivity and lower overpotential. One of the candidates to overcome this scaling relationship is metal sulfide. According to the computational study, since sulfur atoms work as an adsorptio

Abstract:

A transition metal induced C-C coupling by the reaction of W2(N(CH3)2)6, (4) and CS2 yielded the zwitter ion S2C-C(N(CH3)2)2 (1d) besides W2(N(CH3)2)2(CS2)2S4 (5). The com- plex chemistry of the zwitter ions 1d and S2CC(N(CH2)4X)2 (X = CH2, O) has been investigated by their reaction with (η5-C5H5)2Mo2(CO)4 (2) and (η5-C5H5)Mo(CO)3Cl (3). Reaction of the former led to complexes (η5-C5H5)Mo(CO)2(S2CR) (R = N(CH3)2, N(CH2)4X) and the new compounds [(η5-C5H5)Mo(CO)2(S2C-CR2)]+. X-ray structure analyses of 1d and ((η5-C5H5)Mo(CO)2(S2C-C(N(CH2)5)2)]⊕PF6⊖ (10b) are described.

Abstract:

The α-iminocarboxylato chelate complexes RuH(CO)[OOC-C(R1)=N-R2](PPh3)2 (1), η6-p-cymene)RuCl[OOC-C(R)=N-CH2CO2Me] (3) and Cp*CoI[OOC-C(R1)= N-R2] (4) have been obtained from RuHCl(CO)(PPh3)3, [(η6-p-cymene)RuCl2] and Cp*Co(CO)I2, respectively and 2-oxocarboxylate/amine. The structure of (η6-p-cymene)RuCl[OOC-C(CH3)= N-CH2CO2Me] (3a) has been determined by X-ray diffraction. By use of diamines the corresponding dinuclear cobalt and iridium complexes (5, 6) are formed from 2-oxocarboxylate and Cp*Co(CO)I2 or [Cp*IrCl2]2.

Abstract:

The new [(teeda)CdFe(CO)4]2 complex has been isolated from the reaction of [(NH3)2CdFe(CO)4]n with tetraethylethylenediamine. Unlike previous structural reports of ligand adducts of [L2CdFe(CO)4]x complexes, which have all been trimeric species composed of six-membered Cd3Fe3 rings, the teeda complex crystallized as a dimer, analogous to [(2,2-bpy)ZnFe(CO)4]2. As in the zinc dimer, significant distortion arises from steric interactions between the axial carbonyl ligands on opposing iron centers. The complex sits on an inversion center, leading to two independent Cd–Fe distances, 2.7244(6) and

Polyazomethine (PAM) prepared from the polycondensation between p-phenylene diamine (PDA) and p-terephthalaldehyde (PTAl) via Schiff reaction can physically crosslink (complex) with Co ions. Co-complexed PAM (Co-PAM) in the form of gel is calcined to become a Co, N-co-doped carbonaceous matrix (Co-N-C), acting as cathode catalyst of an anion exchange membrane fuel cell (AEMFC). The obtained Co-N-C catalyst demonstrates a single-atom structure with active Co centers seen under the high-resolution transmission electron microscopy (HRTEM). The Co-N-C catalysts are also characterized by XRD, SEM,

In the cation, the CoIIatom is coordinated by six N atoms of two C(py)4ligands in a distorted octahedral geometry. In the anion, the CoIIatom is coordinated by the N atoms of four NCS−ligands in a distorted tetrahedral geometry.

Abstract:

Single-atom catalysts (SACs) within carbon matrix became one of the most promising alternatives to noble metal-based catalysts for oxygen reduction reaction (ORR). Although SACs have significant benefits in reducing the total catalyst cost, it also has the disadvantages of weak interaction between atoms and poor stability. Hence, there is still much room for improvement for the catalyst activity. In response, we designed a Fe-Co-Pt ternary metal single atom catalyst anchored on covalent organic framework (COF)-derived N-doped carbon nanospheres (Pt, Fe, Co/N-C).
