Summary: Hydrogen has the potential to be a green energy source for cars, but the lack of effective hydrogen storage materials is a major obstacle. This study explores the hydrogen storage capacity and reversibility of the Ti-functionalized metal carbyne framework (MCF) with carbyne as an organic linker and Mg4O as an inorganic moiety. The Ti-functionalized MCF can adsorb up to five H-2 molecules per Ti atom with adsorption energy within the range specified by the DOE. The proposed Ti-functionalized MCF shows high gravimetric density and reversibility, making it a potential hydrogen storage medium meeting DOE standards.

Summary: The effect of functional groups (O, F, or OH) on the hydrogen storage properties of Ti2X (X = C or N) monolayer was systematically investigated. It was found that Ti2X(OH)2 monolayer has a larger reversible hydrogen storage capacity than Ti2XO2 and Ti2XF2 monolayers. The binding energy of the OH group at the F site is stronger than the binding energy of H atom, indicating that H2 molecules will not dissociate on Ti2X(OH)2 monolayer. Molecular dynamic simulation showed stable adsorption and desorption of H2 molecules on Ti2X(OH)2 monolayer through Dewar-Kubas interaction at suitable temperatures. Therefore, Ti2X(OH)2 monolayer is a promising reversible hydrogen sorbent storage material under ambient conditions.

Summary: In this study, NaY-zeolites were modified by combining Cu ion-exchange and Na2O or CuO impregnation for adsorptive desulfurization. The results showed that Na2O promoted the adsorption of TBM, while CuO inhibited it. Among the tested samples, the Cu ion-exchanged Y-zeolite containing Na2O showed the most efficient adsorption performance with a 3.97 wt% uptake for TBM, which is 30% higher than that of the Cu ion-exchanged Y-zeolite. The Cu ion-exchanged Y-zeolite containing CuO showed the lowest adsorption ability with a 2.21 wt% uptake for TBM.

Bimetallic materials show higher electrocatalytic activity than monometallic materials, while carbon-coated and doped MOF catalysts exhibit stable and good OER activity. The synergistic interaction between polymetallic active sites effectively improves the intrinsic activity of MOF on OER.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
