    摘要： The present application discloses an aqueous iodine-based battery based on multi-electron transfer, the main structure of which comprises a positive electrode, a negative electrode, a current collector, an electrolyte, and a separator. A porous carbon felt is used as the electrode material on both sides of the positive and negative electrodes, and a polymer film is used as the membrane material. Both the positive and negative electrolytes are stored in the porous carbon felt electrodes. Both the positive and negative electrolytes are acidic mixed solutions containing I- and Cd2+; during charging, I- at the positive electrode is charged to Cd(IO3)2, which realizes a electrochemical reaction of six-electron transfer; and the negative electrode involves the deposition of Cd2+ as a Cd metal; and the process is reversed during discharging. The energy densities of the battery calculated based on the volume of the positive electrolyte can reach about 1100 Wh/L. In order to improve the kinetics and reversibility of the multi-electron transfer process, additional additives are added to the solution to improve the electrochemical reversibility of the overall reaction, so that the battery can achieve an energy efficiency of more than 77% at a current density of 80 mA/cm2 and operate stably for more than 500 cycles.

    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： The present application discloses a method for preparing a hierarchical porous TS-1 molecular sieve, which uses a silicon-titanium ester polymer as both titanium source and silicon source. In the method, silicon and titanium are uniformly connected to a same polymer, and the hydrolysis rates thereof are equivalent during hydrolysis, which can prevent TiO 2 precipitation and reduce the generation of non-framework titanium. Further, the silicon-titanium ester polymer is not only used as both silicon source and titanium source, but also can be used as mesoporous template in the synthesis process. The obtained TS-1 molecular sieve has mesoporous structure with narrow pore size distribution, which plays an important role in promoting the application of TS-1 molecular sieve in the field of catalysis.
