A review on platinum(0) nanocatalysts for hydrogen generation from the hydrolysis of ammonia borane

This review reports a survey on the progress in developing highly efficient platinum nanocatalysts for the hydrolytic dehydrogenation of ammonia borane (AB). After a short prelude emphasizing the importance of increasing the atom efficiency of high cost, precious platinum nanoparticles (NPs) which are known to be one of the highest activity catalysts for hydrogen generation from the hydrolysis of AB, this article reviews all the available reports on the use of platinum-based catalysts for this hydrolysis reaction covering (i) early tested platinum catalysts, (ii) platinum(0) NPs supported on oxides, (iii) platinum(0) NPs supported on carbonaceous materials, (iv) supported platinum single-atom catalysts, (v) bimetallic- and (vi) multimetallic-platinum NP nanocatalysts, and (vii) magnetically separable platinum-based catalysts. All the reported results are tabulated along with the important parameters used in the platinum-catalyzed hydrolysis of AB. In the section "Concluding remarks and a look towards the future" a discussion is devoted to the approaches for making high cost, precious platinum catalysts as efficient as possible, ultimately lowering the cost, including the suggestions for the future research in this field.


A comparative study of the influence of N, N '-dialkyl vs. N, N '-diaryl-based electron donor ancillary ligands on photocurrent and photovoltage in dye-sensitized solar cells (DSSCs)
Ashraf, Saba; Yıldırım, Erol; Akhtar, Javeed; Siddiqi, Humaira M.; El-Shafei, Ahmed (2017-08-21)
In this study, we report the synthesis of a novel heteroleptic Ru(II)-sensitizer, (Ru(2,2'-bipyridine-4,4'dicarboxylic acid)-4,4'-bis(4-piperidin-1-yl) phenyl ethenyl)-(2,2'-bipyridine) (NCS)(2), denoted as SD-1; moreover, its photophysical, electrochemical, and photovoltaic performances were compared with those of N719 and K77-7 (N, N'-diaryl Ru-sensitizer, namely Ru(2,2'-bipyridine-4,4'-dicarboxylic-acid)4,4'- bis(2-(4-N, N'-diphenylaminophenyl) ethenyl)-2,2'-bipyridine (NCS) 2). The photovoltaic performa...
A Study on development of machinable calcium phosphate based bio-composites with zirconia, boron oxide and lanthanum oxide
Khoshsima, Sina; Evis, Zafer; Özgül, Metin; Department of Biomedical Engineering (2015)
The aim of this study was to investigate the microstructure, mechanical and biological properties of pure hydroxyapatite and composites of hydroxyapatite with zirconia, boron oxide and lanthanum oxide. Hydroxyapatite was synthesized via precipitation method and sintered at 1100°C for 1 h. It was observed that relative density of the sintered composites including zirconia was increased while the density of composites including boron oxide decreased. For physical and structural analysis, X-ray diffraction, sc...
A review of research on steel eccentrically braced frames
Kazemzadeh Azad, Sina; Topkaya, Cem (2017-01-01)
This paper reviews the research conducted on steel eccentrically braced frames (EBFs). Both component level and system level responses for such braced frames are treated and discussed. For the component level response, a thorough review of the investigations on links, which are the primary sources of energy dissipation in EBFs, has been presented. The results of experimental and numerical studies on strength, rotation capacity, and overstrength of links are discussed. Furthermore, studies on the effects of ...

This paper describes a screening model for evaluating the migration of organic and inorganic contaminants leached from land-disposed wastes. The model is composed of a waste-zone release submodel, an unsaturated-zone transport submodel and a saturated-zone transport submodel. The waste-zone submodel assumes steady one-dimensional vertical flow through a uniform waste zone treated as a "stirred tank reactor". Soluble inorganic contaminants are assumed to exhibit a constant concentration in the leachate until...
How to increase the catalytic efficacy of platinum-based nanocatalysts for hydrogen generation from the hydrolysis of ammonia borane
Özkar, Saim (2022-01-01)
It reports how to increase the overall catalytic performance of precious platinum nanocatalysts in hydrolytic dehydrogenation of ammonia borane which requires enhancement of both catalytic activity and reusability of the nanocatalysts as well as the fraction of active sites over the total platinum atoms. The following approaches are reported for increasing the utilization efficiency of platinum-based nanocatalysts: (i) The use of colloidal nanoparticles is an efficient way of increasing catalytic activity. ...
