“…Furthermore, they manufactured a membrane module by welding 18 membranes, which was applied to extract ultra-pure H 2 . Jo et al [67] adopted a Pd/Ta composite membrane for ammonia dehydrogenation, overcoming H 2 embrittlement and producing H 2 with a purity over 99.9999%, while the NH 3 concentration was reduced below 1 ppm. Additionally, they applied the Pd/Ta composite membrane to purify H 2 from the CO, CO 2 , H 2 O, and H 2 gas mixture, yielding a H 2 purity of more than 99.999% and a CO content of 10 ppm [68].…”

Nowadays, we face a series of global challenges, including the growing depletion of fossil energy, environmental pollution, and global warming. The replacement of coal, petroleum, and natural gas by secondary energy resources is vital for sustainable development. Hydrogen (H2) energy is considered the ultimate energy in the 21st century because of its diverse sources, cleanliness, low carbon emission, flexibility, and high efficiency. H2 fuel cell vehicles are commonly the end-point application of H2 energy. Owing to their zero carbon emission, they are gradually replacing traditional vehicles powered by fossil fuel. As the H2 fuel cell vehicle industry rapidly develops, H2 fuel supply, especially H2 quality, attracts increasing attention. Compared with H2 for industrial use, the H2 purity requirements for fuel cells are not high. Still, the impurity content is strictly controlled since even a low amount of some impurities may irreversibly damage fuel cells’ performance and running life. This paper reviews different versions of current standards concerning H2 for fuel cell vehicles in China and abroad. Furthermore, we analyze the causes and developing trends for the changes in these standards in detail. On the other hand, according to characteristics of H2 for fuel cell vehicles, standard H2 purification technologies, such as pressure swing adsorption (PSA), membrane separation and metal hydride separation, were analyzed, and the latest research progress was reviewed.

“…In addition, electrocatalytic ammonia decomposition to generate hydrogen gas can be achieved under low-temperature conditions (<450 C), which facilitates the large-scale implementation of this technology. 14,16,96 As shown in Figure 7A, the process from storing ammonia to release energy from hydrogen contains five steps: ammonia storage, ammonia decomposition, hydrogen separation and purification, hydrogen storage and compression, as well as last hydrogen use. 16 Among them, the ammonia decomposition process will be mainly discussed in this section.…”

“…Fortunately, ammonia is easier to store and transport and can decompose to hydrogen without carbon emission, which makes it a feasible medium of hydrogen storage. In addition, electrocatalytic ammonia decomposition to generate hydrogen gas can be achieved under low‐temperature conditions (<450°C), which facilitates the large‐scale implementation of this technology 14,16,96 …”

Nitrogen, one of most important elements on the Earth, plays an essential role in shaping the modern society. The natural nitrogen looping, however, is insufficient to satisfy the high demand of the large-scale human activities. To achieve a more sustainable and efficient utilization of nitrogen, artificial nitrogen looping by photo(electro)catalytic processes has been considered as a feasible strategy. In this context, the rational design on the high-performance catalysts for nitrogen looping becomes increasingly important and urgent. On this basis, herein, we provide a timely review on the recent progress, achievements, and essential challenges for the artificial nitrogen looping process, mainly including photo(electro)catalytic transformations among dinitrogen, ammonia, gaseous nitrogen oxides, nitrate, and so on. Especially, the photo(electro)catalysts used in various reactions involved in nitrogen looping, including nitrogen reduction reaction, nitrogen oxidation reaction, ammonia oxidation reaction, ammonia decomposition reaction, etc., are systematically introduced. Finally, we hope that this review will help us deepen the understanding of nitrogen looping-related photo(electro)catalysts, and further pave a way toward the sustainable development on energy and environment. K E Y W O R D Senvironmental protection, nitrogen looping, photo(electro)catalysis, sustainable energy Mengying Li and Xiaoqing Liu contributed equally to this study.

The integration of membranes inside a catalytic reactor is an intensification strategy to combine separation and reaction steps in one single physical unit. In this case, a selective removal or addition of a reactant or product will occur, which can circumvent thermodynamic equilibrium and drive the system performance towards a higher product selectivity. In the case of an inorganic membrane reactor, a membrane separation is coupled with a reaction system (e.g., steam reforming, autothermal reforming, etc.), while in a membrane bioreactor a biological treatment is combined with a separation through the membranes. The objective of this article is to review the latest developments in membrane reactors in both inorganic and membrane bioreactors, followed by a report on new trends, applications, and future perspectives.
