Abstract Size and shape controlled, in particular, scaling-down synthesis of uniform metal organic frameworks (MOFs) is a challenge. Importantly, MOFs derivatives have received great interest in energy fields owing to their highly porous structure and large surface areas. Here, we demonstrate the controllable large-scale synthesis of highly uniform cuboid-shape MOFs using an eco-friendly method at room temperature. The cuboid-shape ZIF-L is first synthesized until now. We have also explored its derivatives, which are applied in the fields of lithium-ion batteries. As a result, ZnCo 2 O 4 cuboids demonstrate high discharge capacity of 995 mA h g −1 at 100 mA g −1 for the second cycle, high rate capacity of 482 mA h g −1 at 3 A g −1 , and long-term cyclic stability up to 250 cycles at 500 mAg −1 . The porous ZnO cuboids exhibit good photocatalytic activity by degrading dyes (MB, RhB, and MO). The results demonstrate that ZIF-L cuboids and their derivatives have a good application prospect.
