英文摘要	Mineral carbonation in aqueous solutions presents a pragmatic avenue for tackling the challenges associated with carbon capture, utilisation, and storage, particularly in limiting global temperature rise to 1.5 degrees C for climate change mitigation. The urgency to engineer the removal of atmospheric CO2 has driven the exploration of innovative methods for direct conversion into valuable products, with a specific emphasis on calcite as a promising approach for carbon dioxide sequestration. This investigation focuses on the biomimetic strategy of emulating the catalytic activity of carbonic anhydrase by synthesizing a zinc-based metal-organic framework. The MOF, synthesized with Zinc as the central metal coordinated by 1,2,3-benzene tricarboxylic acid, displays noteworthy structural adaptability, diversity, and an extensive surface area. The characterisation of synthesised materials through UV DRS, XRD, XPS, FTIR, SEM, and Raman analyses corroborates its structural features. A comparative study with a Nickel-based MOF (Ni-BTC-MOF) underscores the advantages of zinc over nickel in CO2 mineralisation experiments. Remarkably, Zn-BTC-MOF demonstrates superior catalytic activity, reusability, solvent compatibility, and thermal stability compared to Ni-BTC-MOF. The Zn-BTC-MOF catalyst achieves a mineralisation yield of 25 mg, comparable with the reported results for natural carbonic anhydrase (34.92 mg) and imidazole-carbonic anhydrase (21.55 mg). The Zn-BTC-MOF catalyst displays exceptional reusability, maintaining CO2 mineralisation activity across over a broad pH and temperature range. These findings underscore the potential of Zn-BTC-MOF as an effective biomimetic catalyst for carbon dioxide mineralisation, holding promising applications in carbon capture and utilization technologies.
