Summary In this study, the water recovery performance from flue gas with ceramic membrane tubes of different pore sizes 30, 50, and 200 nm was experimentally studied. The effects of flue gas temperature, flue gas flow rate, water coolant temperature, and water coolant flow rate on the water recovery performance were analyzed. In addition, in the experimental study of SO2 permeability, the pH of the water coolant inlet and outlet was measured using a pH meter to analyze the SO2 permeability of ceramic membranes during the water recovery process. The results show that the water recovery performance of the 50 nm pore size ceramic membrane is better than that of the other two types of ceramic membrane in most cases. The maximum amount of reclaimed water and the highest water recovery rate are 4.82 kg/(m2·h) and 80.3%, respectively. Under the same SO2 concentration condition, the SO2 permeation flux of the 30 nm pore size ceramic membrane is smallest, and that of the 200 nm membrane is the largest. When the SO2/N2 mixed gas flow rate is 6 L/min, the SO2 permeation flux of the 30 and 200 nm membranes is 0.407 and 0.635 mmol/(m2·h), respectively. The ceramic membrane with smaller pore size can block more SO2 permeation, while the ceramic membrane with larger pore size can remove SO2 better.

“…116,122 Significant researched have been conducted to investigate the hydrogen storage of MOFs at cryogenic and ambient temperature. [124][125][126][127][128][129][130][131] Latroche et al, 132 133 Other researchers have also reported the reduction in hydrogen storage capacity at elevated or ambient temperature. This problem has been attributed to the presence of weak adsorption sites on the MOFs and hydrogen.…”

Metal-organic frameworks (MOF) have emerged as a promising material for green engineering applications due to their attractive properties. But the successful implementation of this material in the field of fuel cell technologies is still a challenge. Researchers have reported more than 50% reduction in experimental bulk density of compacted MOFs relatively to their theoretical crystal density. This has resulted in reduction of gravimetric and volumetric H 2 storage capacities of MOFs. Significant experimental research should be directed toward the consolidation of MOFs to meet (6.5 wt%; 50 g/L) 2025 DoE target for onboard H 2 storage systems. We present an overview of green engineering materials for hydrogen storage systems. The review also summarizes recent advancement in the consolidation of MOFs as absorbents for hydrogen storage. The influence of densification techniques on MOFs textural properties, mechanical stability were discussed. Hydrogen storage capacity of both powder and densified high-performance MOFs were presented.

SUMMARY Li‐O2 battery has attracted much attention due to its ultra‐high theoretical energy density in the field of electrochemical energy storage. The introduction of efficient electrocatalyst can effectively accelerate the reaction rate of ORR and OER, so as to improve the coulomb efficiency and poor cycle stability of Li‐O2 battery. In this work, a novel hollow N‐doped carbon sphere is prepared by using MOF and polystyrene as template, and act as highly efficient oxygen electrocatalyst for rechargeable Li‐O2 batteries. The hollow structure can provide enough oxygen diffusion channel, deposition and decomposition space for reduction products. N doping into the hollow carbon structure can increase the charge density of adjacent carbon atoms and enhance its catalytic activity of ORR/OER. As a result, the Li‐O2 battery using the hollow N‐doped carbon sphere as air cathode exhibited an high specific capacity of 18 762 mAh/g (at a current density of 500 mA/g) and remarkable cycling stability of 212 cycles (at a current density of 500 mA/g and limited capacity of 1000 mAh/g), outperforming the carbon material with common structure. This work highlights the importance of air cathode structure and efficient catalyst, provides a new idea for the design of air cathode of Li‐O2 battery, and expands the scope of future research.
