of this report and is included here only to assess the efficacy of our modified synthesis. The measured PXRD pattern for HKUST-1 shows good agreement with that simulated from the crystallographic model 37 (Figure ). The broad reflections at 2θ = 16.56°, 23.7°, 33.99°, 36.06°, 38.01°, and 39.86° can be attributed to copper hydroxide impurities generated during the synthesis of the MOF. These copper oxide impurities are not unexpected given the high water content of the solvent mixture used to synthesize the material, as well as exposure to ambient conditions during drying. The BET surface area 52 of the HKUST-1 sample was determined by N2 gas adsorption at 77 K (Figure ). The sample was activated at 65 °C for 15 h under reduced pressure (~50 mTorr) prior to analysis. The BET surface area was measured to be 1434 m 2 /g, typical for
