“…In the C 1s spectrum, three peaks can be seen: the peak centered at 284.7 eV corresponded to sp 3 C–C bonds of graphitic carbon, the peak around 288.2 eV corresponded to sp 2 -bonded carbon in the heterocycle (N–CN) of aromatic CN, and the lesser one at 285.5 eV was assigned to C–O bonds. 41,42 The XPS spectra revealed that all of the samples possessed a tri- s -triazine structure, which was in good agreement with the XRD analysis. Four peaks at approximately 398.7 eV, 400.1 eV, 401.1 eV, and 404.4 eV were found in the N 1s spectrum (Fig.…”

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...

Among various kinds of photocatalytic semiconductors, graphitic carbon nitride (g-C 3 N 4 )-based photocatalysts have become the most attractive "celebrity" because of their stable chemical properties, appropriate band structure, and facile synthesis. Here, we provide a systematic review of g-C 3 N 4based photocatalytic materials based on the latest related research progress. The design ideas and preparation methods of g-C 3 N 4based photocatalysts are summarized, including morphology control of a three-dimensional structure, active site engineering, defect/vacancy engineering, and interface engineering. In addition, the typical applications of g-C 3 N 4 -based photocatalysts are also discussed in detail, involving water splitting (overall water splitting, H 2 evolution, O 2 evolution), organic transformation reactions (oxidation reaction, reduction reaction, coupling reaction), and degradation of organic pollutants. This perspective ends with a summary and perspectives on facing the challenges and directions of future development in this research field.
