Nanomeshes with highly regular, permeable pores in plane, combining the exceptional porous architectures with intrinsic properties of 2D materials, have attracted increasing attention in recent years. Herein, a series of 2D ultrathin metal–organic nanomeshes with ordered mesopores is obtained by a self‐assembly method, including metal phosphate and metal phosphonate. The resultant mesoporous ferric phytate nanomeshes feature unique 2D ultrathin monolayer morphologies (9 nm thickness), hexagonally ordered, permeable mesopores of 16 nm, as well as improved surface area and pore volume. Notably, the obtained ferric phytate nanomeshes can directly in situ convert into mesoporous sulfur‐doped metal phosphonate nanomeshes by serving as an unprecedented reactive self‐template. Furthermore, as advanced anode materials for Li‐ion batteries, they deliver excellent capacity, good rate capability, and cycling performance, greatly exceeding the similar metal phosphate‐based materials reported previously, resulting from their unique 2D ultrathin mesoporous structure. Therefore, the work will pave an avenue for constructing the other 2D ordered mesoporous materials, and thus offer new opportunities for them in diverse areas.

二维有序介孔铁基金属有机纳米网格的一般构造。

近年来,具有在平面中高度规则,可渗透的孔的纳米网格结合了出色的多孔结构和2D材料的固有特性,引起了越来越多的关注。在此,通过自组装方法获得了一系列二维的有序介孔的超薄金属有机纳米网格,包括金属磷酸盐和金属膦酸盐。将得到的介孔铁植酸纳米网拥有独特的2D超薄单层形态( 9纳米厚)六边形有序的,可渗透的孔的,16 nm,以及改善的表面积和孔体积。值得注意的是,所获得的植酸铁纳米晶可以作为前所未有的反应性自我模板,直接原位转化为介孔的硫掺杂金属膦酸酯纳米晶。此外,作为锂离子电池的高级阳极材料,它们具有出色的容量,良好的倍率性能和循环性能,其独特的二维超薄介孔结构使其大大超过了以前报道的类似的金属磷酸盐基材料。因此,这项工作将为构建其他2D有序介孔材料铺平道路,从而为他们在不同领域提供新的机会。
