Synthesis and catalytic performance of a novel RuCuNi/CNTs nanocomposite in hydrolytic dehydrogenation of ammonia borane

Cu@Pd/C with Controllable Pd Dispersion as a Highly Efficient Catalyst for Hydrogen Evolution from Ammonia Borane

“…To reduce the consumption of noble metals, the addition of another non-noble metal was a useful option. The electronic structures of the noble metal catalysts could be modulated by the non-noble metal to obtain a more efficient bimetallic catalyst [ 30 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 ]. During the preparation of the bimetallic catalyst, burying the noble metal atoms in the metal nanoparticles should be avoided to get full utilization of the noble metals.…”

Interface design of environmentally friendly carbon nanotube-filled polyester composites: Fabrication, characterisation, functionality and application

“…The previous researches has used acid-etched carbon nanotubes to increase the number of -COOH groups on the surface side chains, thus increasing the polar groups on the carbon nanotube surface. For example, Chen et al [20] used a mixture of concentrated sulfuric and hydrochloric acids, Xiong et al [21] used recycled concentrated sulfuric and nitric acids, and Bajada et al [22] used concentrated hydrochloric acid with ultrasonic treatment. In the 1980s, the three-dimensional (3D) printing technologies have been gradually used in the field of rapid prototyping to accelerate commercial product research and development.…”

Hydrolysis of ammonia borane and hydrazine borane by poly($N$-vinyl-2-pyrrolidone)-stabilized CoPd nanoparticles for chemical hydrogen storage

“…Similarly, the average TOF value of CoPd @ PVP nanoparticles in the hydrolysis of HB is lower than that of Rh @ HAP NPs (115 min −1 ) 36 and RhCl 3 (100 min −1 ) 37 but higher than that of Ni 0.9 Pt 0.1 @ graphene (4 min −1 ) , 31 Pd @ PVP NPs (42.9 min −1 ), 32 NiPt @ CeO 2 (3.9 min −1 ), 33 PSSA-co-MA stabilized Co(0) NPs (6.2 min −1 ), 34 PSSA-co-MA stabilized Ni(0) NPs (3.1 min −1 ), 35 CeO x -RhNi @ rGO (11.1 min −1 ) , 38 and Cu @ SiO 2 (7.6 min −1 ) , 39 as seen from Table 2. The observed rate constants (k obs ) for hydrogen release from hydrolysis reactions of AB and HB were calculated from the linear parts of the plots given in Figure 6 and are shown in Tables 3 and 4 The energy of activation value of CoPd @ PVP nanoparticles in the hydrolysis of AB is higher than that of RuCuCo @ MIL-101 (48 kJ mol −1 ) , 6 RuCuNi @ CNTs (36.7 kJ mol −1 ), 11 AuCo @ CNT (38.8 kJ mol −1 ), 15 and NiAgPd/C (38.4 kJ mol −1 ), 21 but lower than that of Ru @ nanodiamond (50.7 kJ mol −1 ), 12 AgPd @ UIO-66-NH 2 (51.8 kJ mol −1 ), 13 and PdPt @ PVP NPs (51.7 kJ mol −1 ) , 18 as seen from Table 1.…”

“…The XPS spectrum of the CoPd @ PVP nanoparticles was obtained by SPECS spectrometer equipped with a hemispherical analyzer and using monochromatic Mg-Kα radiation (1250 eV, the X-ray tube working at 15 kV and 350 W). 11 B NMR spectra were recorded on a Bruker Avance DPX 400 MHz spectrometer.…”
