    摘要: The present disclosure discloses a nickel-iron catalytic material, a preparation method thereof, and a use thereof in the hydrogen production through water electrolysis and the preparation of a liquid solar fuel (LSF). The nickel-iron catalytic material is prepared by using a soluble iron salt as a raw material and growing on a modified nickel substrate under mild conditions, and the nickel-iron catalytic material can be used in the industrial alkaline water electrolysis under harsh conditions. The nickel-iron catalytic material includes a nickel metal substrate and a catalytically-active layer with iron and nickel. When used to promote a water splitting reaction, the nickel-iron catalytic material of the present disclosure can reduce the energy consumption per m 3 of hydrogen production through industrial alkaline water electrolysis from 4.4 kWh to 4.01 kWh, thereby increasing the conversion of solar energy to methanol by 9.7%. The nickel-iron catalytic material involves a simple preparation process and low cost, and can easily realize the industrial scale-up preparation. Through this process, solar energy can be converted into a conventional fuel that can be conveniently stored and transported, which provides a new way to solve energy and environmental problems, and brings huge economic and social benefits.

    摘要: A short-wavelength laser-excitation chiral Raman Spectrometer (A short-wavelength laser-excitation Raman Optical Activity Spectrometer) comprises a laser-excitation light source between 325nm and 532nm, the linear polarized homogeneous system, circularly polarized light converter, sample cell holder, circularly polarized light splitter, double beam bifurcated optical fiber, Rayleigh line filter, imaging spectrometer, CCD sensitive to short-wavelength range and data processing system. The laser coming from laser-excitation light source goes through the linear polarized homogeneous system then exposures to the sample cell, or the laser coming from laser-excitation light source goes through the linear polarized homogeneous system and circularly polarized light converter then exposures to the sample cell. The left/right circularly polarized Raman signals coming from sample cell go through the Rayleigh line filter, then enter into the incidence end of Y-type double-beam optical fiber, divided into two beams of polarized light via circularly polarized light splitter, present as a linear array on the other end of the optical fiber, then enter into the incident slit of imaging spectrograph. The Raman signals are separated by the imaging spectrograph then enter the CCD on the exit of spectrograph which is sensitive in a wide range of short wavelength, and incident upon the top half and the bottom of it. CCD's acquisition system collects the light signals of the top half and the bottom half, that is, the right and the left ciculaly polarized Raman signals, converting them into electrical signals and transmitting the signals to the computer. After data processing, the sum of right and left circularly polarized Raman signals is counted as the total Raman signal, and the difference between right and left circularly polarized Raman signals as the circularly polarized Raman difference signal, that is, the Raman optical activity signal, and One acquisition when normalized difference of circular polarization intensity is computed as the circularly polarized Raman difference signal divided by the total Raman signal. The short-wavelength chiral Raman Spectrometer that can be applied to confirmation of chiral molecules' and biomolecules' absolute configurations, is a powerful tool for determination of absolute configuration and conformation of chiral molecules in wide region of chemistry, biology and medicine.
