CO2的水合反应是CO2吸收（在水溶液中）和含水CO2矿化的速率限制步骤之一。镍纳米粒子（NiNPs）的催化活性CO2水合研究在不同的温度，pH值，和低CO2分压，以模拟真实的烟气条件。结果表明，NiNPs可以作为CO2水合的活性催化剂，用于CO2分离和CO2矿化等应用。NiNPs在20-30 ℃和pH值范围内表现出最佳活性
Hydration reaction of CO2 is one of the rate limiting steps for CO2 absorption (in aqueous solutions) and aqueous CO2 mineralization. The catalytic activity of nickel nanoparticles (NiNPs) for CO2 hydration is studied at different temperatures, pH, and low CO2 partial pressures to mimic the true flue gas conditions. Results show that NiNPs can work as active catalyst for hydration of CO2 in applications such as CO2 separation and CO2 mineralization. The NiNPs display optimum activity within 20-30 degrees C and at pH value
