    Discrete chiral organic nanotubes by stacking pillar[5]arenes using covalent linkages - 1 year(s) ago

    Shi and Fa et al. report covalent organic nanotubes with 5-fold symmetry by stacking two pillar-shaped macrocycles through dynamic covalent linkages. Three different chiral nanotubes are separated, providing one-dimensional channels with different chirality. When binding with guest molecules, two pillar[5]arene cavities communicate with each other, resulting in allosteric binding affinities.

    Medium-independent hydrogen atom binding isotherms of nickel oxide electrodes - 1 year(s) ago

    The O–H bond dissociation free energies (BDFEs) and their distribution are reported for nickel oxide electrode surfaces. These BDFEs and the H-atom binding isotherms are remarkably independent of any changes in the solvent in contact. The unprecedented medium independence establishes these as important intrinsic parameters to describe metal oxide redox reactivity.

    In operando investigations of oscillatory water and carbonate effects in MEA-based CO2 electrolysis devices - 1 year(s) ago

    Membrane electrode assembly CO2 electrolyzers allow commercially relevant current densities. However, there is limited understanding on why or how CO2 electrolysis shifts toward hydrogen production. Herein, operando X-ray scattering reveals a direct observation of salt precipitation and electrolyte flooding in the copper gas diffusion electrode (GDE). The observed oscillations in selectivity and…

    Chlorine-promoted copper catalysts for CO2 electroreduction into highly reduced products - 1 year(s) ago

    Chlorine modification of copper electrocatalysts can be beneficial for conversion of carbon dioxide selectively into highly reduced products, but poor understanding overshadows the potential to tailor catalysts. Here, Zou and Veenstra et al. reveal how the copper phase and chlorine interact to create a promotional effect, providing design guidelines for copper catalysts.

    Full-volatility emission framework corrects missing and underestimated secondary organic aerosol sources - 1 year(s) ago

    Organic aerosol is an important air pollutant worldwide that influences both human health and climate. The concentration and constituents of organic aerosol have long been poorly reproduced by air-quality models. To tackle this problem, Chang et al. focused on organic emission inventory, the primary input of air-quality models. By introducing a new emission framework with a full volatility…

    Stepwise photoassisted decomposition of carbohydrates to H2 - 1 year(s) ago

    Biomass photoreforming is an advanced way of providing sustainable H2, whereas a maximized H2 yield relies on high extent of C–C bond breaking. Here, relying on a “C–C bond first” strategy that C–C bonds of carbohydrates are broken first over Ta-CeO2, carbohydrates are converted to C1 liquid hydrogen carriers (LHCs, consisting of HCOOH and HCHO), which release H2 in high yield when degrading….
