Electrochemical reduction of CO 2 (CO 2 RR) into valuable hydrocarbons is appealing in alleviating the excessive CO 2 level. We present the very first utilization of metallic bismuth–tin (Bi-Sn) aerogel for CO 2 RR with selective HCOOH production. A non-precious bimetallic aerogel of Bi-Sn is readily prepared at ambient temperature, which exhibits 3D morphology with interconnected channels, abundant interfaces and a hydrophilic surface. Superior to Bi and Sn, the Bi-Sn aerogel exposes more active sites and it has favorable mass transfer properties, which endow it with a high FE HCOOH of 93.9 %. Moreover, the Bi-Sn aerogel achieves a FE HCOOH of ca. 90 % that was maintained for 10 h in a flow battery. In situ ATR-FTIR measurements confirmed that the formation of *HCOO is the rate-determining step toward formic acid generation. DFT demonstrated the coexistence of Bi and Sn optimized the energy barrier for the production of HCOOH, thereby improving the catalytic activity.

Porous Tantalum Nitride Single Crystal at Two‐Centimeter Scale with Enhanced Photoelectrochemical Performance

引用

Angewandte Chemie 2020年第23期132卷

Porous tantalum nitride (Ta 3 N 5 ) single crystals, combining structural coherence and porous microstructure, would substantially improve the photoelectrochemical performance. The structural coherence would reduce the recombination of charge carriers and maintain excellent transport properties while the porous microstructure would not only reduce photon scattering but also facilitate surface reactions. Here, we grow bulk‐porous Ta 3 N 5 single crystals on a two‐centimeter scale with (002), (023), and (041) facets, respectively, and show significantly enhanced photoelectrochemical performance. We show the preferential facet growth of porous crystals in a lattice reconstruction strategy in relation to lattice match and lattice channel. We present the facet engineering to enhance light absorption, exciton lifetime and transport properties. The porous Ta 3 N 5 single crystal boosts photoelectrochemical oxidation of alcohols with the (002) facet showing the highest performance of >99 % alcohol conversion and >99 % aldehyde/ketone selectivity.

Full‐Spectrum Persistent Luminescence Tuning Using All‐Inorganic Perovskite Quantum Dots

Applications of persistent luminescence phosphors as night or dark‐light vision materials in many technological fields have fueled up a growing demand for rational control over the emission profiles of the phosphors. This, however, remains a daunting challenge. Now a unique strategy is reported to fine‐tune the persistent luminescence by using all‐inorganic CsPbX 3 (X=Cl, Br, and I) perovskite quantum dots (PeQDs) as efficient light‐conversion materials. Full‐spectrum persistent luminescence with wavelengths covering the entire visible spectral region is achieved through tailoring of the PeQD band gap, in parallel with narrow bandwidth of PeQDs and highly synchronized afterglow decay owing to the single energy storage source. These findings break through the limitations of traditional afterglow phosphors, thereby opening up opportunities for persistent luminescence materials for applications such as a white‐emitting persistent light source and dark‐light multicolor displays.

A New Class of Blue‐LED‐Excitable NIR‐II Luminescent Nanoprobes Based on Lanthanide‐Doped cas Nanoparticles

Lanthanide (Ln 3+ )‐doped luminescent nanoparticles (NPs) with emission in the second near‐infrared (NIR‐II) biological window have shown great promise but their applications are currently limited by the low absorption efficiency of Ln 3+ owing to the parity‐forbidden 4f→4f electronic transition. Herein, we developed a strategy for the controlled synthesis of a new class of NIR‐II luminescent nanoprobes based on Ce 3+ /Er 3+ and Ce 3+ /Nd 3+ co‐doped cas NPs, which can be effectively excited by using a low‐cost blue light‐emitting diode chip. Through sensitization by the allowed 4f→5d transition of Ce 3+ , intense NIR‐II luminescence from Er 3+ and Nd 3+ with quantum yields of 9.3 % and 7.7 % was achieved, respectively. By coating them with a layer of amphiphilic phospholipids, these NPs exhibit excellent stability in water and can be exploited as sensitive NIR‐II luminescent nanoprobes for the accurate detection of an important disease biomarker, xanthine, with a detection limit of 32.0 n m .

Tuning Shell Thickness of MnO/C Core-shell Nanowires for Optimum Performance of Lithium-ion Batteries

引用

Chemical Research in Chinese Universities 2017年第6期33卷 924-928页

作者： ZHANG Dan LI Guangshe FAN Jianming LI Baoyun LI Liping State Key Laboratory of Inorganic Synthesis and Preparative Chemistry College of Chemistry Jilin University Changehun 130012 P. R.

MnO/C core-shell nanowires with varying carbon shell thickness were synthesized via calcining resorci- nol-formaldehyde resin（RF） with different amounts of hydrothermally synthesized MnO2 nanowires. The relationship between the carbon shell thickness and the anode performance of the MnO/C materials was discussed. With a suitable carbon shell thickness（6.8 nm）, the MnO/C core-shell nanowires exhibit better cycling and rate performance than those with a smaller or larger thickness. The TEM results show that after 50 cycles, the core-shell structure with this thickness can be retained, which leads to superior performance. This contribution provides a significant guiding model for optimizing the electrochemical performance of MnO/C core-shell materials by controlling the thickness of carbon shells.
