Cu-MOF-74 (also known as Cu-CPO-27) was identified a sorbent having one of the highest densities Cu(ii) sites per unit volume. Given that in framework can be thermally activated to yield five-coordinate species, we this MOF potential candidate for maximal volumetric uptake ammonia. To end, kinetic breakthrough ammonia Cu-MOF-74/Cu-CPO-27 examined under both dry and humid conditions. Under conditions exhibited respectable performance (2.6 vs. 2.9 NH3 nm(3) current record holder HKUST-1), 80% relative humidity, outperformed HKUST-1 (5.9 3.9 nm(3), respectively).
