Summary: In this study, hierarchical CuO hollow microspheres were synthesized using a simple hydrothermal method. The synthesized samples were characterized using X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The results showed that the hierarchical CuO hollow microspheres, composed of primary nanorods with diameters of about 20 nm, self-assembled into uniform spheres with a diameter of 3 μm. The hollow microspheres had a wall thickness of about 200 nm. The hierarchical CuO hollow microspheres exhibited excellent sensing performance in H2S and ethanol detection, with high selectivity and low detection limit.

Summary: The increasing demand for hazardous gas detections has led to the development of mesoporous materials for gas sensors. This study successfully synthesized mesoporous structures for semiconductor oxides using a universal method. The gas sensing response to ethanol can be regulated by adjusting the morphology and thickness of the mesoporous nanosheets. Furthermore, the method shows excellent repeatability and can be applied to various oxide materials.

Summary: In this study, hierarchical porous hydroxyl aluminum oxide hollow microspheres with controllable structure and morphology were prepared. The CO2 trapping performance of potassium carbonate-based adsorbents prepared using these microspheres as supports was evaluated. The results showed that the loading of potassium carbonate, the pore structure, and the surface basic site of the adsorbent significantly influenced its CO2 trapping performance.

Summary: This study reports a cost-effective and simple process to create strong, highly porous ceramics via direct ink writing of suspensions of hollow microspheres into cellular architectures with pores at three hierarchical levels. X-ray diffraction, rheological measurements, scanning electron microscopy, and mechanical tests are conducted to thoroughly study the processing steps and morphology of the printed hierarchical porous ceramics. The presence of pores at multiple length scales significantly increases the mechanical strength of the porous structure, providing a useful platform for the manufacturing of lightweight ceramics from inexpensive and widely available feedstock materials.

Summary: This study investigated the stabilization mechanism of Pickering emulsion using mesoporous hollow silica microspheres (MHSMs) as stabilizers. The results showed that smaller particle size and shell thickness of MHSMs can improve the stability of Pickering emulsion, and MHSMs with intermediate hydrophobicity and suitable oil/water ratio are favorable for stability. Increasing the concentration of MHSMs within a certain range can enhance the stability of Pickering emulsion, with the optimal concentration being 1.25 mg/mL. This research opens up possibilities for the fabrication of functional materials through Pickering emulsions.

Summary: The authors designed and synthesized Mn selectively doped CoP hollow microspheres to trap LiPSs and enhance Li-S reaction kinetics in lithium-sulfur batteries. The selective doping of Mn improved the adsorption capacity for LiPSs and inhibited the shuttle effect, while also accelerating the reduction kinetics of sulfur redox conversion. The optimal electrode exhibited excellent cycling stability.

Summary: The issue of narrow micropores in traditional protonic type Zeolite Socony Mobil-5 (HZSM-5) catalysts, which restrict the diffusion of large-molecular reactants/products, was tackled by preparing hollow HZSM-5 with a mesoporous shell. The efficient catalyst of Hollow(30)-TP showed significantly higher aromatic hydrocarbon yields for cellulose and hemicellulose compared to traditional HZSM-5, and exhibited excellent reusability and regeneration due to increased accessibility to acid sites.
