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].
