MXenes have emerged as a new kind of 2D transition metal carbides, nitrides and carbonitrides. Origined from the unique 2D structure with a luxuriant combination of elements, MXenes drive a series of the investigations related to energy storage and conversion, biometrics and sensing, lighting, purification and separation. For 2D layered MXene materials, the interspacing confined by the independent MXenes layers affords a distinct confinement space, which is similar to a nanoreactor that can be utilized for the storage of ions, nanoparticles, nanowires, and the materials with 2D or 3D structure. These fillings confined by MXene layers afford new opptunities for achieving improved properties and performance via complementary natural features, further the synergistic effect. Herein, we summarize the recent reports concerning with the confinded MXenes spacing and the fillings. The modification of interlayer distance lead by the intercalants were explored. We expect that our review may offer the route for a series of ongoing studies to address the MXenes.

MXene已成为一种新型的2D过渡金属碳化物，氮化物和碳氮化物。MXenes源自具有丰富元素组合的独特2D结构，它推动了一系列与能量存储和转换，生物识别和传感，照明，净化和分离有关的研究。对于2D层状MXene材料，由独立MXenes层限制的间隙提供了明显的限制空间，类似于可以用于存储离子，纳米粒子，纳米线以及具有2D或3D结构的材料的纳米反应器。这些由MXene层限制的填充物提供了新的机会，可通过互补的自然特征实现更高的性能和性能，并进一步发挥协同效应。在这里 我们总结了有关受限MXene间距和填充的最新报告。探索了嵌入剂对层间距离的影响。我们希望我们的审查可能会提供一系列正在进行的研究以解决MXene的方法。
