Molybdate-Templated Luminescent Silver Alkynyl Nanoclusters: Total Structure Determination and Optical Property Analysis.

Two novel MoO-templated luminescent silver alkynyl nanoclusters with 20-nuclearity ([(MoO)@Ag(C≡CBu)(PhPO)(tfa)]·(tfa) ()) and 18-nuclearity ([(MoO)@Ag(C≡CBu)(PhPO)]·(OH) ()) (tfa = trifluoroacetate) were synthesized with the green light maximum emissions at 507 and 516 nm, respectively. The nanoclusters were investigated and characterized by single-crystal X-ray crystallography, electrospray ionization mass spectrum (ESI-MS), X-ray photoelectron spectroscopy, thermogravimetry (TG), photoluminescence (PL), ultraviolet-visible (UV-vis) spectroscopy, and density functional theory calculations (DFT). The two nanoclusters differ in their structure by a supplementary [Ag(tfa)] organometallic surface motif, which significantly participates in the frontier molecular orbitals of , resulting in similar bonding patterns but different optical properties between the two clusters.

Boosting the lithium-ion storage performance of perovskite SrVO via Sr cation and O anion deficient engineering.

Perovskite SrVO has been investigated as a promising lithium storage anode where the V cation plays the role of the redox center, combining excellent cycle stability and safe operating potential versus Li metal plating, with limited capacity. Here, we demonstrate the possibility to boost the lithium storage properties, by reducing the non-redox active Sr cation content and fine-tuning the O anion vacancies while maintaining a non-stoichiometric SrVO perovskite structure. Theoretical investigations suggest that Sr vacancy can work as favorable Li storage sites and preferential transport channels for guest Li ions, contributing to the increased specific capacity and rate performance.

Cu/PCN Metal-Semiconductor Heterojunction by Thermal Reduction for Photoreaction of CO-Aerated HO to CHOH and CHOH.

g-CN-based materials show potential for photoreduction of CO to oxygenates but are subjected to fast recombination of photogenerated charge carriers. Here, a novel Cu-dispersive protonated g-CN (PCN) metal-semiconductor (m-s) heterojunction from thermal reduction of a CuO/PCN precursor was prepared and characterized using in situ X-ray diffraction, scanning transmission electron microscopy, X-ray photoelectron spectroscopy, ultraviolet-visible (UV-vis) spectra, photoluminescence (PL) spectra, transient photocurrent response, and electrochemical impedance spectroscopy (EIS). The Cu amount in Cu/PCN and the reduction temperature affected the generation of CHOH and CHOH from the photoreaction of CO-aerated HO.
