摘要

氨硼烷（AB）水解是一种可持续的高效氢能转换和运输方法。设计一种具有高催化活性的非贵金属硼烷水解催化剂被认为前景广阔但极具挑战性。在此，通过在过渡金属碳化物（Ti3C2Tx）上采用传统的湿化学共还原法，成功制备了高度分散的 Cu0.9Ni0.1 合金纳米颗粒（NPs），从而促进了 AB 水解过程中的氢气进化。优化后的 Cu0.9Ni0.1/Ti3C2Tx 催化剂在 323 K 条件下进行 AB 水解时的翻转频率 (TOF) 高达 2429 h-1，氢选择性为 100%，优于大多数非贵金属催化剂。这种性能的提高归因于铜和镍之间的协同效应，以及 Ti3C2Tx 和 Cu0.9Ni0.1 NPs 之间强烈的电子金属-支撑相互作用。这项研究为合成高效的非贵金属 AB 水解催化剂提供了一种通用而简单的方法。

Two-dimensional titanium carbide-supported ultrafine non-noble bimetallic nanocatalysts for remarkable hydrolytic evolution from ammonia borane†

Ammonia borane (AB) hydrolysis is a sustainable and efficient method for hydrogen energy conversion and transportation. Designing a non-precious AB hydrolysis catalyst with high catalytic activity is considered to be promising but challenging. Herein, highly dispersed Cu_0.9Ni_0.1 alloy nanoparticles (NPs) were successfully fabricated via a conventional wet-chemical co-reduction method on transition metal carbides (Ti₃C₂T_x), facilitating hydrogen evolution during AB hydrolysis. The optimized Cu_0.9Ni_0.1/Ti₃C₂T_x catalyst exhibits an impressive turnover frequency (TOF) of 2429 h⁻¹ at 323 K for AB hydrolysis, with 100% hydrogen selectivity, outperforming those of most non-precious metal catalysts. This enhanced performance is attributed to the synergistic effect between Cu and Ni, as well as the strong electronic metal–support interaction between Ti₃C₂T_x and Cu_0.9Ni_0.1 NPs. This study provides a general and simple method for synthesizing highly efficient non-precious metal AB hydrolysis catalysts.
