Enhanced Carbon Sequestration Performance and Mechanism of Adsorption-Catalytic Bifunctional ZIF‑8 Coupled Microalgae.

ABSTRACT: To support the development of a low-carbon economy and contribute to the achievement of carbon neutrality, this study synthesized bifunctional zeolitic imidazolate framework-8-based nanozymes (ZNZs) with dual functionality: CO₂ adsorption and carbonic anhydrase (CA)-mimetic catalytic activity. The influence of ZNZs at varying concentrations on the growth rate of microalgae, chlorophyll and carbohydrate content, and ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and CA activity were explored. Results indicated that after the addition of 5 mg/L ZNZs, the growth rate of microalgae increased by 7%. Furthermore, the maximum chlorophyll and carbohydrate contents reached 4.55 and 43.59 mg/L, respectively, which were 12.6 and 4.2% higher than those in the control group. Addit
