Ultrafine and highly dispersed Ru nanoparticles supported on nitrogen-doped carbon nanosheets: Efficient catalysts for ammonia borane hydrolysis

Ru Nanoparticles Embedded in Cubic Mesoporous Silica SBA-1 as Highly Efficient Catalysts for Hydrogen Generation from Ammonia Borane

“…The activities of the metal NPs confined in mesoporous supports also depend on the unique textural properties of the support, chemical nature of the surface, and interactions among the metal NPs and the oxides. The higher catalytic activity of the catalyst Ru/HPCM (hierarchically porous carbon material) was attributed to the ultrafine Ru NPs, high porosity, and abundant nitrogen and oxygen-rich groups in the hierarchically porous carbon material (HPCM) support that facilitated the stabilization of Ru NPs and prohibited them from aggregation [28]. Being the most active amongst all the catalysts investigated here, Ru(1)@S1B-C10 was selected to analyze the effect of reaction temperature on the performance of the catalyst.…”

“…The reaction takes place is expressed as [22,23] NH 3 BH 3 + 2H 2 O → NH + 4 + BO 2− + 3H 2 (1) The development of a proper catalyst with high catalytic performance for hydrogen release by means of AB hydrolysis has prompted significant research attention over the past decades. Noble metals, such as Pt [24], Pd [25], Ag [26], and Ru [27][28][29] based catalysts, can promptly generate hydrogen from AB and hence have been touted as greatly effective catalysts. However, the scarcity of resources and high cost of noble metals are the great challenges for their extensive application.…”

A simple and straightforward strategy for synthesis of N,P co-doped porous carbon: an efficient support for Rh nanoparticles for dehydrogenation of ammonia borane and catalytic application

“…We have reported that N or P-doped carbons as MNP supports enhanced catalytic activities for AB decomposition. [28][29][30] We have also been exploring a simple and effective method for N,P co-doped nanocarbon fabrication, which is promising from the viewpoints of both economical and environmental issues. In the choice of raw material enriched with N or P, adenosine triphosphate disodium (ATP) is an excellent candidate owing to the high abundance of N and P offered by one adenine structure and three phosphate groups, respectively.…”

Ultrafine Pd Nanoparticles Supported on Soft Nitriding Porous Carbon for Hydrogen Production from Hydrolytic Dehydrogenation of Dimethyl Amine-Borane

“…In addition, the removal of such protecting molecules under harsh conditions also results in the loss of catalytic activity [21]. Recent studies have indicated that the heteroatom-doped carbon materials can be used as ideal platforms to synthesize ligand-free metal NPs for catalytic applications [17,[22][23][24]. However, most of the synthetic strategies for heteroatom-doping of carbon matrixes are conducted by strong acid treatment and high temperature calcination, leading to the production of carbon materials with relatively low content of heteroatom, which are adverse to the preparation of metal NPs with ultrafine sizes [25].…”
