1. This catalyst demonstrated the highest TOF value of 454.06 mol H2 mol Pt min -1 and the activation energy of 41.82 kJ mol -1 at 25 ?. Moreover, the excellent catalytic activity of NiTi-LDH@B 12 H 12 @Pt 2.4% can be attributed to several factors, including the mild reducibility of [closo-B 12 H 12 ] 2-, the small particle size and uniform distribution of Pt clusters (2.49 nm), large specific surface area (210.568 m 2 /g), and the synergistic catalytic effect of Pt and NiTi-LDH that accelerates electron transfer. Furthermore, the catalytic hydrolysis of AB are1.15-order and 0.24-order dependence on Pt and AB concentrations, respectively. Moreover, NiTi-LDH@B 12 H 12 @Pt 2.4% demonstrates excellent catalytic performance after five cycles. The facile preparation method, excellent catalytic and reusability make NiTi-LDH@B 12 H 12 @Pt 2.4% a green catalyst for AB hydrolysis with good application prospects. The strategy and method described here have good reference and inspiration for the design and application of catalysts;CRediT authorship contribution statement Haixu Zhao: Writing -original draft, Investigation.
