Inter-ligand concerted mechanismCatalytic benzene C-H activation toward selective phenol synthesis with O2 remains a stimulating challenge to be tackled. Phenol is currently produced industrially by the three-steps cumene process in liquid phase, which is energy-intensive and not environmentally friendly...

The number of species involved in the process, their XANES spectra and their concentration profiles as a function of the temperature were obtained by MCR and PCA. Mixed ligand ammonia solvated complexes [CuII(NH3)3(X)]+ (X = OH−/O− or NO3−) are present at the beginning of...
In the MoL3-edge X-ray absorption spectra of α-MoO3and Fe2(MoO4)3(Fig.2b), two peaks of α-MoO3are readily assigned to the Mo 2p3/2 → 4d(t2g0) and 4d(eg0) transitions, respectively, with a ligand-field splitting energy of∼3.1 eV for a MoO6octahedral symmetry (Oh)...

Typically, these compounds present a three-dimensional framework constructed from the formate ligand and metal ions, where a counter-ion is located in the cavities. The formate ligand has the ability to mediate ferro- or antiferro-magnetic interactions between the connected metal ions, depending on...

The trans effect series is argued to be dominated by the σ-donor ability of the trans ligand with strong σ donors having a labilizing effect on the trans position. π-Acceptor ligands which are not strong σ donors deactivate both the cis and trans sites. For the more limited cis ...
Tailoring the morphology of Pt nanocrystals (NCs) is of great concern for their enhancement in catalytic activity and durability. In this article, a novel synthetic strategy is developed to selectively prepare porous dendritic Pt NCs with different struc
The organic–inorganic hybrid perovskite compounds have been extensively studied since the dawn of a new era in the field of photovoltaic applications. Up to now, perovskites have proven to be the most promising in terms of power conversion efficiency; h
