HKUST-1 (CAS number: 222404-02-6) is a copper-based metal organic framework constructed from copper centers and benzene-1,3,5-tricarboxylate (BTC) linkers. The crystal structure of HKUST-1 is built up by secondary building units called paddlewheel units. The paddlewheel units, where two copper ions are bridged by four BTC linkers, not only contribute to the high surface area (1,350 m²/g) but also provide structural rigidity with thermal stability up to 240 °C.

HKUST-1 has multiple applications, including CO₂ capture, drug delivery and batteries. HKUST-1 can capture water pollutants (i.e. Cr³⁺ ion) with adsorption capacity of 84.3 mg/g. The purification process occurs via adsorption active sites and ionic exchange between copper and chromium ions. HKUST-1 is also applied in the direct air capture of CO₂. When incorporated with graphene oxide, it demonstrates CO₂ capture capacities of up to 6.92 mmol/g.
