Synergistic Catalysis of Binary RuP Nanoclusters on Nitrogen-Functionalized Hollow Mesoporous Carbon in Hydrogen Production from the Hydrolysis of Ammonia Borane

Abstract: Exploring highly efficient nanocatalysts for hydrogen (H 2 ) production from catalytic hydrolysis of ammonia borane (AB) under ambient conditions and further unveiling their catalytic mechanism are of critical importance for renewable energy conversion technologies but remain big challenges. Herein, ultrafine binary RuP alloy nanoclusters homogeneously encapsulated onto nitrogen-functionalized hollow mesoporous carbon supports (RuP@NHMCs) are reported as a high-performance platinum (Pt)free nanocatalyst for ca… Show more

“…The corresponding TOF value is 111.1, 238.2, 325.1, 331.8 min −1 when the NaOH concentration is 0, 0.4, 0.8 and 1.2 M, respectively (Figure 10b). This can be ascribed to the coordination of OH − ions with the surface of Ru NPs, providing more electron for the Ru/CS catalysts, thus accelerating the oxidation of the O−H bond of water [46] . On the other hand, when further increasing the NaOH concentration to 1.6 M, an opposite behavior happens, and the corresponding TOF value reduces to 263.1 min −1 .…”

“…Literature reveals that the cleavage of the O−H bond of water is the rate‐determining step of AB hydrolysis [Eqs. (3–6)] [46] . To further improve the reaction rate, we studied the effect of different NaOH concentrations, and the results are shown in Figure 10.…”

“…In our case, Cu 2 + being strongly electron deficient readily react with BÀ H bond of AB. [37][38][39][40] In subsequent step, [CuH] + Cl can undergo disproportionation reaction to give CuH, CuCl and HCl. As Cl[H 2 BNH 3 ] is not a stable species in water, it readily undergoes hydrolysis to B(OH) 3 and H 2 .…”

“…23,[33][34][35][36][37][38] However, limited success has been achieved in applying the geometric effect of (hollow) mesoporous metals to adjust the selectivity of the products in hydrogenation reactions, although supported metal nanoclusters within mesoporous matrixes have been studied to enhance catalytic activity. [39][40][41] Hollow mesoporous metal nanocrystals were synthesized through templating strategies. Their mesoporous frameworks are formed by nucleation and growth of metal atoms around the self-assembled surfactants, while their interior nanocavity is generated by sequential removal of the sacrificial templates.…”
