二维层状结构MXenes因其优异的电学性能、可调控的表面官能团而被广泛应用于钾离子超级电容器领域，但其有限的双电容存储容量严重限制了MXenes材料在电极材料的应用。本工作采用“路易斯酸熔盐预刻蚀-液相刻蚀-原位水热复合”策略，制备出以Ti3C2为基体，表面包覆MnO2的Ti3C2基异质结构，以提高电极材料对钾离子的储存。采用基于密度泛函的第一性原理计算方法，研究了Ti3C2基异质结界面之间的连接方式、电学性质以及钾离子吸附规律的变化。结果表明构建的Ti3C2基异质结对钾离子的最大吸附量扩大3倍左右，且Ti-O-H-O连接通道使MnO2内部的自由电子数目增多，导致Ti3C2基异质结表现出优异的电学性能。三电极体系下的电化学测试结果表明Ti3C2基异质结在1 A·g–1的电流密度下能够提供431 F·g–1的比电容，远远高于Ti3C2(128F·g–1)。并通过的动力学分析阐述Ti3C2基异质结的赝电容储能机理，在100 mV·s–1的电压扫描速率下，其赝电容贡献度高达89%，此外Ti3C2基异质结表现出较小的电化学阻抗，从而提高钾离子传输速率、电子转移速率。本研究通过构筑Ti3C2基异质结，提高了基体Ti3C2的电化学性能，并阐述相应的储能机理，这为其他MXenes基电极材料的设计提供了理论基础。

Metal organic frameworks(MOFs) have been considered as compelling precursor for miscellaneous applications. However, their unsatisfied electrocatalytic performance limits their direct application as electrocatalyst. Herein, by incorporating the cobalt-oxide bonds and polyaniline(PANI) with two-dimension zeolitic imidazolate frameworks(ZIFs), a novel bifunctional catalyst(Co-O-ZIF/PANI) for Zn-air battery was designed based on a facile and eco-friendly method. This Co-O-ZIF/PANI with optimized surface adsorption effect and suitable Co^(3+)/Co^(2+)ratio, exhibits eminent electrocatalytic activity toward both oxygen reduction and evolution reaction. The as-assembled liquid ZABs based on Co-O-ZIF/PANI achieves a remarkable maximum power density of 123.1 m W cm^(-2) and low discharge-charge voltage gap of 0.81 V at 5 m A cm^(-2) for over 300 cycles. Operando Raman spectroscopy reveals that the excellent performance origins from the optimized surface chemisorption property of O_(2) and H_(2)O brought by Co–O bonds and PANI. This work provides a novel prospect to develop efficient MOF derived bifunctional electrocatalysts by optimizing surface chemisorption properties.
