This report describes the aims, methods, and findings of the research, with a particular emphasis on the forms and determinants of DSD and the responses to it. We are particularly concerned with moving beyond previous research on DSD, which has had a tendency to focus only on individual cases...
Metal alloys, which are composed of different types of metals, commonly exhibit better performance than their individual components because of synergistic effect [130]. Recently, transition metal alloys have been widely investigated for their application in oxygen electrocatalysis because of their satisfacto...
解析 Ans. Zinc, cadmium and mercury of group 12 have full d10 configuration ( d orbitals arecompletely flled ) in their ground state as well as in their common oxidation states and hence,are not regarded as transition metals 反馈 收藏 ...
In addition to group 6 transition metals (Cr, Mo, and W), Ti (4 valence electrons), V (5), Mn (7), and Fe (8) also form (η6-C6H6)2M complexes. The metal exists in a zero-oxidation state and such compounds are highly covalent due to the large degree of electron delocalization...
0D TMC materials refer to structures with all dimensions being in the range of 1 ~ 100 nm, which typically consist of transition metals from Group IB to Group IIB and chalcogens, with a composition ratio of M:X ranging from 1:1 to 1:2 [43,44,45]. Their unique physical and che...
3). Seminal studies by Yamaguchi and Itami20, and more recently Newman21 established the synthetic utility of O–C(acyl) cleavage in aryl esters by transition metals. The engagement of phenyl esters in transition-metal-catalyzed protocols allows the bench-stable, orthogonal ester moieties to be ...
Low-valent early transition metals are often intrinsically highly reactive as a result of their strong propensity toward oxidation to more stable high-valent states. Harnessing these highly reducing complexes for productive reactivity is potentially powerful for C–C bond construction, organic reductions,...
indicating different catalytic mechanisms [49]. Wang studied the influence of the electron structure on adsorption ability and catalytic performance of SmMn2O5, which was doped with major-group metals Mg, Ga and transition metals V, Cr, Fe, Mo at Mn site. The results showed that the binding ...
Metallocene catalysts, in general, consist of transition metal complexes, most commonly based on Group IV metals, ligated with cyclopentadienyl(Cp)-type groups. A wide range of structures of this type of catalysts is known, including those with substituted, linked and/or heteroatom-containing Cp gr...
