Driven by renewable or excess electrical energy,electrochemical CO_(2)reduction reaction(eCO_(2)RR)represents a promising carbon-neutral approach to generating valuable low-carbon fuels by consuming CO_(2)and H_(2)O.C_(2+)products are one of the most economically valuable products among the reduction species of eCO_(2)RR,but there are still some challenges,such as low selectivity or low current *** this work,we showed that a copper-based metal-azolate framework(MAF),denoted as MAF-203,exhibits the high performance of eCO_(2)RR to yield C_(2+)products with the Faradaic efficiency(C_(2+))of 52.5%and a current density of 660 mA/cm^(2)at-1.2 V *** in a flow cell device under alkaline *** experiment,in situ infrared spectroscopy and the density functional theory(DFT)calculations showed that the electron donating effect of methyl substituents on organic ligands of the copper-based MAF could enhance the ligand field and activation of key intermediates(*CO and*CHO species),thus promoting the coupling of*CO and*CHO for yielding C_(2+)products.

作者： Ze-yuan Tang jun-Jie Feng jun-Hui Fan School of Mathematics and Information Science Guangzhou University Center for Astrophysics Guangzhou University Astronomy Science and Technology Research Laboratory of Department of Education of Guangdong Province Key Laboratory for Astronomical Observation and Technology of Guangzhou

A warm corona has been widely proposed to explain the soft excess （SE） in X-ray above the 2–10 ke V power law extrapolation in Active Galactic Nuclei （AGNs）.In actual spectral fittings,the warm coronal seed photon temperature（Ts） is usually assumed to be far away from the soft X-ray,but kTscan reach close to 0.1 ke V in the standard accretion disk *** this study,we used Monte Carlo simulations to obtain radiation spectra from a slab-like warm corona and fitted the spectra using the spherical-geometry-based routine THCOMP or a thermal *** findings reveal tha high Tscan influence the fitting results.A moderately high kTs（around 0.03 ke V） can result in an apparent low-temperature and flat SE,while an extremely high kTs（around 0.07 ke V） can even produce an unobserved blackbody-like *** conclusions indicate that,for spectral fittings of the warm coronal radiation （SE in AGNs）,kTsshould be treated as a free parameter with an upper limit,and an accurate coronal geometry is necessary when kTs>0.01 ke V.
