Ammonia-borane (AB) is one of the most promising fuel forms for the hydrogen economy, but the reaction requires a good catalyst to accelerate this hydrolysis reaction under ambient conditions. Here, H2 evolution upon hydrolysis of ammonia-borane catalyzed by tetra-(p-hydroxyphenyl) porphyrin (THPP) stabilized transition metal nanoparticles (RhNPs/THPP, RuNPs/THPP, PtNPs/THPP) has been reported for the first time. The as-synthesized nanocomposites (TMNPs/THPP) show high catalytic activity in the AB hydrolysis. Among these TMNPs/THPP, the RhNP-3/THPP exhibits the best catalytic activity with a TOF of 213.64 molH2 molcata−1 min−1. In addition, tandem reaction for 1,1-diphenylethylene hydrogenation has also confirmed the H2 evolution upon hydrolysis of ammonia-borane.

卟啉稳定的纳米催化剂催化氨硼烷水解时的 H2 释放

氨硼烷 (AB) 是氢经济中最有前途的燃料形式之一，但该反应需要良好的催化剂才能在环境条件下加速这种水解反应。在这里，首次报道了由四（对羟基苯基）卟啉（THPP）稳定的过渡金属纳米粒子（RhNPs/THPP、RuNPs/THPP、PtNPs/THPP）催化氨硼烷水解时产生的 H2。合成的纳米复合材料 (TMNPs/THPP) 在 AB 水解中显示出高催化活性。在这些 TMNPs/THPP 中，RhNP-3/THPP 表现出最好的催化活性，TOF 为 213.64 molH2 molcata−1 min−1。此外，1,1-二苯基乙烯加氢的串联反应也证实了氨-硼烷水解时会放出H2。
