Summary: This study proposed a strategy to design a non-existent sulfide ZrO2(MgO)-(CaO-Al2O3) solid electrolyte using the vacuum ion infiltration method. The electrolyte was based on a (Ca2+, Al3+)-infiltrated ZrO2(MgO) porous backbone for direct sulfur determination in molten steel. The experimental results showed that the prepared electrolyte had a well-connected network and rafts, and exhibited excellent wettability with the molten steel, allowing for stable electrochemical signal and accurate sulfur determination. This achievement has great significance in the intelligent control of steel-making.

Summary: Calcium looping is a promising approach for decarbonization of carbon-intensive industries. This study focuses on the development of high-capacity and stable sorbents for commercialization of the process. CaO-based sorbents stabilized with CaZrO3 were synthesized using different fuels. Sorbents synthesized with citric acid showed higher surface area and CO2 uptake capacity. However, under harsh calcination conditions, the stability of the sorbents decreased due to sintering and loss of surface area. Spheronized sorbents exhibited lower uptake capacity and diffusion limitations.

Summary: Calcium looping is a promising method for reducing carbon emissions, and the development of sorbents with high CO2 uptake capacity and cyclic stability is crucial for its commercialization. In this study, CaO-based sorbents stabilized with CaZrO3 were synthesized using the solution combustion synthesis method. The use of different fuels (citric acid and beta-alanine) had an impact on the physical properties and carbon capture performance of the sorbents. The results showed that sorbents synthesized with citric acid had a higher surface area and CO2 uptake capacity compared to those synthesized with beta-alanine. The cyclic stability of the sorbents decreased under harsh calcination conditions, indicating the need for improvement in practical applications.

Summary: MOF materials with adjustable pore structure and polymetallic sites have been explored as electrocatalysts for OER. 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.

Summary: First principles calculations were used to investigate the pathway for methylation of benzene with methane catalyzed by MFI type zeolite-supported Co species. The strong adsorption of benzene on Co is found to lower the activation energy for methane dissociation and promote the formation of toluene precursor. The activation energy of methane dissociation is also affected by the Al-Al distance.
