“…The Pd 3d results (Figure a) can be deconvoluted into four peaks which indicated that Pd was present in two states as both Pd 2+ and metallic Pd. The peaks at 335.5 and 340.7 eV were attributed to Pd 0 , whereas the peaks at 337.6 eV and 342.9 eV were associated with Pd 2+ . It was found that Ag 1 Pd 2 /CN had a higher percentage of electron‐deficient Pd (Pd 2+ ) than the pure Pd/CN (Figure a).…”

Highly dispersed bimetallic AgPd alloy nanoparticles with various ratios have been supported on carbon nitride by using a co‐reduction method and then tested for catalytic dehydrogenation of formic acid without base addictive. It was found that the activity of the catalyst depended directly on the AgPd ratios of the catalyst and the reaction temperature. The Ag1Pd2/CN catalyst exhibited excellent catalytic activity for hydrogen generation from formic acid with the initial TOF of 621 h−1 at 348 K. The synergetic interaction between the bimetallic AgPd nanoparticles and the carbon nitride support, the AgPd ratio and the dispersion of AgPd nanoparticles on the support contribute to the high catalytic performance of the AgPd/CN catalysts.

“…An et al investigated the catalytic behaviour of amine-functionalized SBA-15 (SBA-15-Amine)-supported bimetallic AgPd nanoparticles [78]. According to the experimental methodology used in that study, 3-aminopropyltriethoxysilane (APTES) was used as amine source and the resulting SBA-15-Amine was loaded with Ag and Pd precursors in different proportions to obtain Pd/SBA-15-Amine, Ag 1 Pd 9 /SBA-15-Amine, Ag 3 Pd 7 /SBA-15-Amine, Ag 5 Pd 5 /SBA-15-Amine, Ag 7 Pd 3 /SBA-15-Amine, and Ag/SBA-15-Amine catalysts.…”

The production of H 2 from the so-called Liquid Organic Hydrogen Carriers (LOHC) has recently received great focus as an auspicious option to conventional hydrogen storage technologies. Among them, formic acid, the simplest carboxylic acid, has recently emerged as one of the most promising candidates. Catalysts based on Pd nanoparticles are the most fruitfully investigated, and, more specifically, excellent results have been achieved with bimetallic PdAg-based catalytic systems. The enhancement displayed by PdAg catalysts as compared to the monometallic counterpart is ascribed to several effects, such as the formation of electron-rich Pd species or the increased resistance against CO-poisoning. Aside from the features of the metal active phases, the properties of the selected support also play an important role in determining the final catalytic performance. Among them, the use of carbon materials has resulted in great interest by virtue of their outstanding properties and versatility. In the present review, some of the most representative investigations dealing with the design of high-performance PdAg bimetallic heterogeneous catalysts are summarised, paying attention to the impact of the features of the support in the final ability of the catalysts towards the production of H 2 from formic acid.Energies 2019, 12, 4027 2 of 27 fact, it is challenging not only for developed countries in which the living standard requires large energy supplies, but also for those developing countries that experience a high population growth.Among greenhouse gases, carbon dioxide (CO 2 ) is considered the most important because, even though its global warming potential (GWP) is much lower than that of other gases, the emissions of CO 2 are far more abundant. GWP parameter was developed to compare the global warming impacts of different gases and it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period, relative to the emissions of 1 ton of CO 2 , which is used as the reference. Then, CO 2 has a GWP of 1 regardless of the time used, while GWP is 28-36 and 265-298 times that of CO 2 for methane (CH 4 ) and nitrous oxide (N 2 O), respectively [1]. Such considerations, that are nowadays central scientific and social concerns, have a long historical background within the research community. Arrhenius was among the first to hypothesise about the impact of CO 2 on the Earth's climate [2], but his hypothesis was overlooked until the 1950s [3]. Now, after more than half a century, there is not yet a chemical process able to efficiently clean the growing volumes of CO 2 in the atmosphere. Some interesting actions taken so far are related to the production of hydrocarbon fuels by recycling H 2 O and CO 2 with renewable energy sources or the CO 2 capture and sequestration (CCS) technology [4][5][6][7].In such energy and environmental context, the search for alternative carbon emission-free energy sources is required to avoid further disastrous consequences. Hydrogen (H 2 ), a carbon-free fuel, is consi...

“…Searching efficient and safe hydrogen storage materials has regarded as one of the most difficult troubles for the realization of hydrogen‐based economy from the fossil fuel‐based economy in the future . Among various hydrogen storage materials investigated, hydrous hydrazine(H 2 NNH 2 ⋅H 2 O), which is believed to be one of the most attractive liquid hydrogen carriers owing to the characteristic of high hydrogen content of 8% and easy recharging in the form of liquid phase, can give a feasible approach for safe hydrogen storage . However, the decomposition of hydrazine follows the two routes, namely, a complete decomposition route to produce hydrogen in addition to nitrogen (

{normalH}_{2} NN {normalH}_{2} (normall) \to {normalN}_{2} (normalg) + 2 {normalH}_{2} (normalg)

) and the undesired way to generate nitrogen and ammonia ((

) .…”

Hydrogen generation through catalytically hydrous hydrazine has recently emerged as a promising strategy to meet the everincreasing demand for sustainable energy. However, it remains a challenging obstacle to design highly active catalysts as well as low-cost. In this work, we designed a series of NiPt/CNTs catalysts, which were prepared via a facile wet chemical reduction method, employed it in the dehydrogenation of hydrous hydrazine. The crystalline structure, chemical states and morphology of the catalysts were also characterized in detail. Among these catalysts, Ni 0.4 Pt 0.6 /CNTs exhibits highest activity with a turnover frequency (TOF) of 1725.3 h À 1 at 50°C and a low E a of 36.3 kJ/mol. Considering its cost-effective and high performance, the Ni 0.4 Pt 0.6 /CNTs represent a promising catalyst to hydrolyze hydrous hydrazine for hydrogen generation.[a] Dr.
