Bimetallic cost-effective CoNi nanoparticles (NPs) are conveniently supported on titanium carbides (MXene) by a simple one-step wet-chemical method. The synthesized CoNi/MXene catalysts characterized XPS, TEM, STEM-HAADF and ICP-AES. as-prepared NPs with size of 2.8 nm well dispersed the MXene surface. It is found that among bimetallic system, Co0.7Ni0.3 shows best performance toward catalyzing ammonia borane (AB) decomposition turnover frequency value 87.6 molH2 molcat -1 min-1 at 50 °C. remarkable catalytic attributed to mild affiliation NPs, which not only stabilizes maintain good dispersion but also leaves sufficient surface active sites facilitate reaction.
