| 1 | High-performance liquid-phase catalytic purification of phosphine in tail gas using Pd(Ⅱ)/Cu(Ⅱ)composite显示文摘Pd/Cu liquid-phase composite was utilized as the catalyst in this study to remove PH_(3) at low temperatures.The anti-heterotoxicity of catalysts in the PH_(3) catalytic oxidation purification process was carefully explored and pioneered.The catalytic performance,thermodynamics,kinetics,and catalytic oxidation mechanism of Pd/Cu liquid-phase catalyst catalytic oxidation of PH_(3) were thoroughly investigated.The results showed that Pd/Cu has a superior catalytic effect on the removal of PH_(3) in the gas mixture under low temperature.With CO as the carrier gas,the removal efficiency of PH_(3) could be maintained at 100%for nearly 450 min,indicating that the Pd/Cu liquid phase catalyst has good resistance to heterotoxicity.According to the thermodynamic,kinetic,and related characterization results of the PH_(3) purification process,the kinetic region of the gas–liquid reaction of PH_(3) absorption by Pd/Cu solution was an interfacial reaction.Pd was the primary catalyst and Cu was the secondary catalyst,and the adsorption of PH_(3)was a primary reaction.PH_(3) was spontaneously oxidized to H_(3)PO_(4) in the Pd/Cu catalytic system during the removal process.Pd was regenerated by O_(2) and Cu,increasing the activity and stability of the Pd/Cu catalyst in the sustain and efficient purification of PH_(3) in tail gas. | Chenyang Zhao Yinhan Cheng Guangfei Qu Yongheng Yuan Fenghui Wu Ye Liu Shan Liu Junyan Li Ping Ning | 2023 | Chinese Journal of Chemical Engineering2023，57，5： | 0 |
| 2 | Recent progress in carbon-based electrochemical catalysts:From structure design to potential applications显示文摘Advances in research and development of carbon-based metal-free electrocatalysts(C-MFECs)have provided potential alternatives to precious metal catalysts for various reactions important to renewable energy and environmental remediation.This timely but critical review provides an overview of recent breakthroughs(within the past 5 years or so)on C-MFECs in all aspects,including the design and regulation of intrinsic catalytic active sites,design and synthesis of carbon composite and hybrid carbon catalysts,mechanism understanding,and potential applications in clean energy storage and energy/chemical conversion.Current challenges and future opportunities in the field of metal-free carbon electrocatalysis are also discussed to provide forward-looking opportunities for their potential applications in various catalytic processes of practical significance. | Jixin Yan Fenghui Ye Quanbin Dai Xinyue Ma Zhihai Fang Liming Dai Chuangang Hu | 2023 | Nano Research Energy2023，2，2： | 0 |
| 3 | The allosteric gating mechanism of the MthK channel显示文摘Allostery is a fundamental element during channel gating in response to an appropriate stimulus by which events occurring at one site are transmitted to distal sites to regulate activity.To address how binding of the first Ca^(2+)ion at one of the eight chemically identical subunits facilitates the other Ca^(2+)-binding events in Mth K,a Ca^(2+)-gated K^(+)channel containing a conserved ligand-binding RCK domain,we analysed a large collection of Mth K structures and performed the corresponding thermodynamic and electrophysiological measurements.These structural and functional studies led us to conclude that the conformations of the Ca^(2+)-binding sites alternate between two quaternary states and exhibit significant differences in Ca^(2+)affinity.We further propose an allosteric model of the Mth K-gating mechanism by which a cascade of structural events connect the initial Ca^(2+)-binding to the final changes of the ring structure that open the ion-conduction pore.This mechanical model reveals the exquisite design that achieves the allosteric gating and could be of general relevance for the action of other ligand-gated ion channels containing the RCK domain. | Fenghui Guan Tianyu Li Wei Dong Rui Guo Hao Chai Zhiqiu Chen Zhong Ren Yang Li Sheng Ye | 2022 | National Science Review2022，9，8： | 0 |
