Thermostability indicated that after incubation at 50 ℃ for 6 hours, DAADH-ZIF-8/RGO/Ni-DAADH maintained 70% activity (Fig. 11). The enhancement of activity is consistent with previous literature that a novel multi-metallic system was reported to exhibit higher catalytic efficiency compared with individual metal-based hybrid materials [30]. Bimetal-based MOF displays potential in immobilization with high enzyme loading capacity, stability, and recyclability [31].
