Facile Synthesis of Carbon‐Supported Ultrasmall Ag@Pd Core‐Shell Nanocrystals with Superior Electrocatalytic Activity for Direct Formic Acid Fuel Cell Application

Chinese Journal of Chemistry (2016)

Jianyu Cao Zhentao Zhu Weifang Zhao Juan Xu Zhidong Chen

Abstract To design electrocatalysts with excellent performance, morphology, composition and structure is a decisive influential factor. In this work, ultrasmall Ag@Pd core‐shell nanocrystals supported on Vulcan XC72R carbon with different Ag/Pd atomic ratios are synthesized via a facile successive reduction approach with formaldehyde and ethylene glycol as reducing agents, respectively. The Ag‐core/Pd‐shell nanostructures are revealed by high‐resolution transmission electron microscopy (HRTEM). Ag@Pd core‐shell nanocrystals possess a narrow size distribution with an average size of ca . 4.3 nm. In comparison to monometallic Pd/C and commercial Pd black catalysts, such Ag@Pd core‐shell nanocrystals display excellent electrocatalytic activities for formic acid oxidation, which may be due to high Pd utilization derived from the formation of Ag@Pd core‐shell nanostructure and the strong interaction between Ag and Pd.

o,o-Difluorination of aromatic azide yields a fast-response fluorescent probe for H₂S detection and for improved bioorthogonal reactions

Organic & Biomolecular Chemistry (2017)

Jie Zhang Yasi Gao Xueying Kang Zhentao Zhu Zhiqian Wang

The development of efficient bioorthogonal reactions for sensing of endogenous biomolecules and for bioconjugation should be of paramount importance in the field of chemical biology. In this work, the o,o'-difluorinated aromatic azide was firstly employed to develop a new fast-response fluorescent probe 1 for H2S detection and for bioorthogonal reactions. Compared with non- and mono-fluorinated probes, 1 showed faster reaction toward H2S, the third gasotransmitter, in buffer (pH 7.4), implying that the reaction rate could be enhanced by the dual-fluorine groups. Furthermore, such enhanced reaction rates of 1 were also observed in the Staudinger reaction and strain-promoted azide-alkyne cycloaddition (SPAAC) based on the comparison studies of the non-fluorinated probe. Our results firstly highlight that the o,o'-difluorinated aromatic azide group should be useful for fast bioorthogonal reactions and H2S detection.

Multi‐Fluorinated Azido Coumarins for Rapid and Selective Detection of Biological H₂S in Living Cells

Chemistry - An Asian Journal (2015)

Zhentao Zhu Yanyan Li Chao Wei Xin Wen Zhen Xi

Hydrogen sulfide (H2 S) is an endogenously produced gaseous signaling molecule with multiple biological functions. In order to visualize the endogenous in situ production of H2 S in living cells in real time, here we developed multi-fluorinated azido coumarins as fluorescent probes for the rapid and selective detection of biological H2 S. Kinetic studies indicated that an increase in fluorine substitution leads to an increased rate of H2 S-mediated reduction reaction, which is also supported by our theoretical calculations. To our delight, tetra-fluorinated coumarin 1 could react with H2 S fast (t1/2 ≈1 min) and selectively, which could be further used for continuous enzymatic assays and for visualization of intracellular H2 S. Bioimaging results obtained with 1 revealed that d-Cys could induce a higher level of endogenous H2 S production than l-Cys in a time-dependent manner in living cell.

Preparation of Fe-N-Carbon Nanocoils as Catalyst for Oxygen Reduction Reaction

International Journal of Electrochemical Science (2015)

Shuihua Tang Haixin Huangfu Zhen Dai Leping Sui Zhentao Zhu

Carbon nanocoil (CNC) with large specific surface area of 398 m2g-1 was synthesized by heat-treatment of resorcinol and formaldehyde resin, and Fe-N-CNC and Fe-N-XC72 catalysts with variously nominal Fe contents were prepared by carbonization of in-situ polymerized polyaniline in the presence of CNC or XC72 and Fe species. The Fe-N-C catalysts were characterized by Fourier Transformation Infrared Spectroscopy, X-ray Photoelectron Spectroscopy, Transmission Electron Microscopy, and then oxygen reduction reaction (ORR) activity and stability were determined by cyclic voltammetry (CV) and linear sweep voltammetry. Fe-N-CNC catalyst with Fe nominal content of 5 wt% indicates more pyridinic and graphitic nitrogen, less pyrrolic nitrogen and total N/C ratio, it also demonstrates 30 mV more positive of half-wave potential compared to Fe-N-XC72 catalyst, and after 1000 CV cycles at scan rate of 50 mVs-1, the half-wave potential of Fe-N-CNC catholically shifts 20 mV respect to 40 mV of Fe-N-XC72. This is mainly due to CNC with unique morphology and higher electron conductivity, which facilitate oxygen transportation and further reduction reaction. The ORR activities indicate that the type of nitrogen incorporating in carbon is far more important than the total content of nitrogen.
