    In article number 1902170, Hong Wang, Geoffrey A. Ozin, and co‐workers present a hetero‐nanostructure, oxygen vacancy, electronic band alignment and carrier lifetime engineering strategy of In2O3−x(OH)y@Nb2O5, enabling the solar‐powered, reverse water gas shift reaction to operate at a 44‐fold higher conversion rate than pristine In2O3−x(OH)y, with high selectivity and long‐term operational stability, an advance that augers well for the metal oxide hetero‐nanostructure engineering approach to the industrialization of gas‐phase CO2 photocatalysis [Link]

    In this work, we report the synthesis of flexible, highly conductive and robust N, S co-doped graphitic hollow carbon fibers (CFs) by vacuum carbonization of “human hairs”. By engineering those cost-effective CFs with polydiacetylene (PDA), a new family of ultrasensitive, reversible electrochromatic fibers that display switchable color transition (bluered) upon current and UV-light stimuli was successfully created.

    Heterostructure Engineering of a Reverse Water Gas Shift Photocatalyst, which enables the gas-phase, photocatalytic, heterogeneous hydrogenation of CO2 to CO with high performance metrics. The catalyst is comprised of indium oxide nanocrystals, In2O3-x(OH)y, nucleated and grown on the surface of niobium pentoxide (Nb2O5) nanorods.

  • Aug. 24th 2019: We designed the Cover picture of our Hydrazine fuel cell paper on Angewandte Chemie!

    A hierarchically structured porous carbon membrane containing atomically dispersed semi‐metallic selenium atoms was prepared. In their Research Article (DOI: 10.1002/anie.201907752), W. Zhou, H. Wang, and co‐workers show that the membranes can be utilized as electrodes for the hydrazine oxidation reaction in practical hydrazine fuel cells [Link].

    We report a class of electrochemically active, hierarchically porous carbon membranes containing atomically dispersed semi-metallic Se (denoted SeNCM). It represents the archetype of single semi-metallic atom heterogenous catalyst in which the isolated Se atoms were stabilized by carbon atoms in the form of a hexatomic ring structure, locating at the edges of graphitic domains in SeNCM. The positively charged Se, enlarged graphitic layers, robust electrochemical nature of SeNCM endow them with excellent catalytic activity that is even superior to commercial Pt/C catalyst, and long-term operational stability towards hydrazine oxidation reaction in practical hydrazine fuel cell.

    We report the fabrication of CPMs exclusively from poly(ionic liquid)s, and their pore size and wettability were precisely tailored by rational choice of anions. Specifically, a stepwise subtle increase in hydrophobicity of the anions by extending the length of fluorinated alkyl substituents, i.e. from Tf2N to Pf2N and Hf2N, decreased the average pore size gradually from 1546 to 157 and 77 nm, respectively. Meanwhile, the corresponding water contact angles increased from 90° to 102° and 120°. The sensitive control over the porous architectures and surface wettability of CPMs by variation of anion hydrophobicity provides solid proof of the impact of PIL anions on CPM structures.

    We introduce a straightforward, scalable and technologically relevant strategy to manufacture charged porous polymer membranes (CPMs) in a controllable manner. The pore sizes and porous architectures of CPMs are well-controlled by rational choice of anions in PILs. Continuously, heteroatom-doped hierarchically porous carbon membrane (HCMs) can be readily fabricated via morphology-maintaining carbonization of as-prepared CPMs. These HCMs being as photothermal membranes exhibited excellent performance for solar seawater desalination, representing a promising strategy to construct advanced functional nanomaterials for portable water production technologies.

    Hierarchically porous carbon membranes have been successfully developed by H. Wang, J. Yuan, G. A. Ozin et al.; the membranes can be utilized as high-performance gas-diffusion electrodes to electrochemically convert N2 into NH3 at room temperature and atmospheric pressure in an acidic aqueous solution [Link].

    In this paper, hierarchically structured nitrogen-doped nanoporous carbon membranes (NCMs) are reported to electrochemically convert N2 into NH3 at room temperature and atmospheric pressure in an acidic aqueous solution. The Faradaic efficiency and rate of NH3 production using the metal-free NCM electrode in 0.1 M HCl solution are as high as 5.2% and 0.08 g m-2 h-1, respectively. Upon functionalization of the NCM electrode with Au nanoparticles, the efficiency and rate achieve a remarkable 22% and 0.36 g m-2 h-1, respectively. These performance metrics are unprecedented for the electrocatalytic production of NH3 from N2 under ambient conditions.
