Heteroatom-doped Cu-based catalysts have been found to show not only enhanced activity of electrochemical CO2 reduction reaction (CO2RR) but also the possibility tune selectivity CO2RR. However, complex and variable nature materials renders it difficult elucidate origin improved performance, which further hinders rational design catalysts. Here, we demonstrate that CO2RR can be tuned by manipulating lattice strain The combined operando ex situ spectroscopic characterizations reveal initial...
Abstract Understanding the structure-stability relationship of catalysts is imperative for development high-performance electrocatalytic devices. Herein, we utilize operando attenuated total reflectance surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS) to quantitatively monitor evolution Cu single-atom (SACs) during electrochemical reduction CO 2 (CO RR). SACs are converted into 2-nm nanoparticles through a reconstruction process RR. The rate highly dependent on substrates due...

Photonic topological valley kink states have become a significant research frontier with plethora of applications. Unlike the guided modes adjustable widths in conventional waveguides, are usually highly confined around domain walls. They thus lack mode width degree freedom (DOF), posing serious limitation to potential device Here, by adding photonic crystal (PhC) featuring Dirac points between two PhCs opposite valley-Chern numbers, we design and experimentally demonstrate valley-locked...

Abstract In the photothermal synergistic catalytic conversion of CO 2 and H O, catalyst harnesses solar energy to accumulate heat, thereby elevating reaction system’s temperature. The influence this temperature effect on surface chemical reactions remains an underexplored area. Here impact surface-level thermodynamic with O oxide semiconductors at atomic scale was investigated using first-principle calculations. 13 different metal oxides 5 transition clusters were used introduce functional...
Among all types of solar cells, multicrystalline silicon (Si) cells are the most widely produced. The enhancement efficiency Si may help broaden deployment worldwide. Here we show that state-of-the-art commercially produced can be enhanced by a simple inkjet printing Si-quantum-dot (Si-QD) ink at cell surface. It is found results from both down-shifting QDs and antireflection porous Si-QD films current demonstrate Si-based nanotechnology facilitate continuous development traditional cells.
