  • Sequential Self-Reconstruction of Localized Mo Species in Hierarchical Carbon/Co–Mo Oxide Heterostructures for Boosting Alkaline Hydrogen Evolution Kinetics and Durability Reviewed International journal

    Surface self-reconstruction processes in alkaline hydrogen evolution reaction (HER), especially regarding the explicit structure–activity relationships, remain elusive. Here, we first design a hierarchical Co@NCNT/CoMoOx precatalyst constituted by defective CoMoOx nanosheets grafted with flexible Co@NCNT arrays, followed by a delicate anodic treatment for fast dissolution balance. Benefiting from the multi-level Co@NCNT arrays as a stable micro-environment, the resultant Co@NCNT/CoMoyOx displays excellent electrocatalytic activity with a low overpotential of 195 mV at −100 mA cm−2 and stable 600 h operation for the HER in alkaline media, including natural seawater, which is better than most reported carbon/transition metal-based catalysts. In situ Raman analyses disclose a local high-resolution self-reconstruction evolution of localized Mo species at controllable negative potentials. Density functional theory calculations further demonstrate that the ultimate Mo–Mo surface state accelerates reaction kinetics to promote H2 generation in alkaline media. Our findings provide a unique insight into the mechanism of the structural evolution in the alkaline HER process to pave a new avenue guiding the design of durable and efficient catalysts.

  • Artificial visual systems enabled by quasi–two-dimensional electron gases in oxide superlattice nanowires Reviewed International journal

    Language:English   Publishing type:Research paper (scientific journal)  

    Rapid development of artificial intelligence techniques ignites the emerging demand on accurate perception
    and understanding of optical signals from external environments via brain-like visual systems. Here, enabled by
    quasi–two-dimensional electron gases (quasi-2DEGs) in InGaO3(ZnO)3 superlattice nanowires (NWs), an artificial
    visual system was built to mimic the human ones. This system is based on an unreported device concept
    combining coexistence of oxygen adsorption-desorption kinetics on NW surface and strong carrier quantumconfinement effects in superlattice core, to resemble the biological Ca2+ ion flux and neurotransmitter release
    dynamics. Given outstanding mobility and sensitivity of superlattice NWs, an ultralow energy consumption down
    to subfemtojoule per synaptic event is realized in quasi-2DEG synapses, which rivals that of biological synapses
    and now available synapse-inspired electronics. A flexible quasi-2DEG artificial visual system is demonstrated to
    simultaneously perform high-performance light detection, brain-like information processing, nonvolatile charge
    retention, in situ multibit-level memory, orientation selectivity, and image memorizing.
