The direct construction of a C(sp.)-S-P(O) moiety from unactivated terminal alkynes remains highly challenging. Alkynyl phosphorothioates are obtained by coupling terminal alkynes and P(O)SH. Using com. available and inexpensive Ru(bpy)₃Cl₂ and copper as a catalyst, this cross dehydrogenative coupling reaction is first performed under photoirradiation Direct use of stable P(O)SH and terminal alkynes without the need to prepare unstable S-X and P-X derivatives represents a prominent advantage of this method. More attractively, this operationally simple reaction avoids the use of odorous thiols and poisonous alkynyl bromides.

It is vitally important to develop high-efficiency low-cost catalysts to boost oxygen reduction reaction (ORR) for renewable energy conversion. Herein, an A-CoN₃S₁@C electrocatalyst with at. CoN₃S₁ active sites loaded on N, S-codoped porous carbon was produced by an at. exchange strategy. The constructed A-CoN₃S₁@C electrocatalyst exhibits an unexpected half-wave potential (0.901 V vs. reversible hydrogen electrode) with excellent durability for ORR under alk. conditions (0.1 M KOH), superior to the com. platinum carbon (20 weight% Pt/C). The outstanding performance of A-CoN₃S₁@C in ORR is due to the pos. effect of S atoms doping on optimizing the electron structure of the at. CoN₃S₁ active sites. Moreover, the rechargeable zinc-air battery in which both A-CoN₃S₁@C and IrO₂ were simultaneously served as cathode catalysts (A-CoN₃S₁@C &IrO₂) exhibits higher energy efficiency, larger power d., as well as better stability, compared to the compound Pt/C&IrO₂-based zinc-air battery. The present result should be helpful for developing lower cost and higher performance ORR catalysts which is expected to be used in practical applications in energy devices.

A novel, environmentally friendly electrocatalytic process was developed to prepare α,α-gem-dihalide (F, Cl, and Br) ketones from α-mono-halide ketones in an aqueous solution containing alkali halide salts. The gem-dihalides had the same or different halogens on the same carbon, depending on the reactant and inorganic halide salt used. An electron-withdrawing group, such as carbonyl, located at the α-site of mono-halogenated carbon, was essential to the reaction. The electrosyntheses were performed under ambient conditions without inert gas protection and displayed yields of about 80%. This method avoided the classical haloform elimination reaction. However, when the aqueous solution contained NaOH, two α-mono-halide ketone mols. had a special dimer condensation. The reaction mechanisms were explored by conducting GC-MS, EPR, and CV with DFT calculations These revealed that in situ generation of a halogen radical initiated electrocatalytic halogenation, while the dimer condensation involved a hydroxyl radical-mediated C1 fragment elimination.

Zhou, Wu;Ye, Zhiping;Nikiforov, Anton;Chen, Jun;Wang, Jiade;Zhao, Liang;Zhang, Xiuwen research published 《 The influence of relative humidity on double dielectric barrier discharge plasma for chlorobenzene removal》, the research content is summarized as follows. The influence of relative humidity on the elec. characteristics, the generation of the active species and the chlorobenzene removal performance was studied. The results show that both the peak-to-peak current and the discharge power decreased with the increase of relative humidity under the same peak-to-peak voltage. A reduction of electron temperature was observed with the addition of water vapor, affecting the electron impact processes. It was observed that excited states of N2 and O were affected by the water due to the quenching effect. A decrease of chlorobenzene removal efficiency was achieved from 81.7% to 70.7% as the increase of humidity. However, carbon balance anal. depicts the yields of CO2 in humid air were higher than that in dry air due to the help of radical OH, especially in RH = 40%, and highest energy efficiency with 4.4 g kW-1 h-1 was also achieved at RH = 40%. Chlorine balance indicates that the product HCl is more easily generated in the presence of H2O. A difference in the chlorobenzene degradation pathway was revealed. Fewer kinds of benzenoid byproducts were found in dry air, which was in agreement with the plasma diagnostics results. Radicals generated in humid air promoted the total oxidation process, resulting in fewer kinds of ring-open byproducts and higher CO2 yield.

Zhu, Lei;Liang, Gaolei;Guo, Chuanpan;Xu, Miaoran;Wang, Minghua;Wang, Changbao;Zhang, Zhihong;Du, Miao research published 《 A new strategy for the development of efficient impedimetric tobramycin aptasensors with metallo-covalent organic frameworks (MCOFs)》, the research content is summarized as follows. Two bimetallic CoNi-based metallo-covalent organic frameworks (MCOFs) were prepared and explored as the sensitive platforms of impedimetric aptasensors for efficient detection of tobramycin (TOB). The two CoNi-MCOFs were constructed using metallophthalocyanine tetra-amine (MPc-TA, M = Co²⁺ or Ni²⁺) and 4,4′-(1,10-phen-anthroline-2,9-diyl) dibenzaldehyde (PTD) as building units and further coordinating to the secondary metal ions (Ni²⁺ or Co²⁺) by phenanthroline. Interestingly, the immobilization ability of CoPc-TA-PTD(Ni) to TOB-targeted aptamer is higher than that of NiPc-TA-PTD(Co) due to its stronger binding interactions to aptamer. As a result, the CoPc-TA-PTD(Ni)-based aptasensor shows the superior TOB detection ability, giving a low detection limit of 0.07 fg mL^-1 and satisfied sensing performances, such as high selectivity, good reproducibility, and excellent stability. Also, the aptasensor shows the acceptable applicability for detecting TOB in milk or chicken egg. This MCOFs-based sensing strategy could be extensively applied to detect other analytes by anchoring the corresponding probes.

A key matter in heavy metal removal technol. is to develop the adsorbents with efficient adsorption sites. In this study, an oxygen-rich covalent organic framework (JUC-505) was functionalized by carboxyl (-COOH) groups to form synergetic effects aiming for the removal of Cd(II) and Pb(II) ions. JUC-505-COOH shows a high Cd(II) uptake of 504 mg·g^-1 surpassing most of the reported porous adsorbents. Meanwhile, the kinetics study shows a rapid adsorption process at a high initial concentration (100 mg·L^-1), and the equilibrium can be reached within 5 min. We investigated the adsorption mechanism in-depth by d. functional theory calculations, proving the synergistic effects of surface complexation and hydrogen-bond, which are from the post-modified -COOH groups and the in-situ oxygen atoms of JUC-505, resp. Moreover, under the interference of common ions in natural water, the removal efficiency of Cd(II) is almost insusceptible, which sheds lights on the potential for the application in the natural water purification In addition, the Pb(II) uptake (559 mg·g^-1) and the adsorption kinetics also surpass most of the reported porous adsorbents.
