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: A facile and supercritical drying-free synthesis strategy is developed for rapid preparation of resorcinol formaldehyde resin organic xerogel. Hierarchical porous carbon xerogel with both amorphous and graphitic regions is obtained via pyrolysis as prepared organic xerogel. The carbon xerogel possesses a high specific surface area of 587 m(2) g(-1) and abundant surface oxygen functional groups. The present work paves a new way for rapid preparation of resorcinol-formaldehyde resin (xero)gel and extends their applications in energy storage devices.

Summary: In this study, a new porous carbon material adsorbent was prepared by assembling carbon microspheres inside hollow carbon spheres using a hydrothermal method. The adsorbents were characterized using various techniques. It was found that increasing the glucose concentration promoted the diameter of carbon microspheres, but coarse microspheres could not be loaded into the mesopores or macropores of hollow carbon spheres. The C0.1@HCS adsorbent showed the highest surface area and pore volume, and had a suitable ratio of micropores and mesopores for providing adsorption sites and volatile organic compound diffusion channels.

Summary: Melamine formaldehyde resin (MF) has limitations in industrial application due to its high cost, high content of free formaldehyde and susceptibility to cracking. Biomass modification of MF offers a solution to these problems. The synthesis of sucrose melamine-formaldehyde copolymer resin (SMF) using sucrose, melamine, and formaldehyde as raw materials under alkaline conditions was studied. The findings revealed that the sucrose content and curing agent had significant impacts on the thermal stability and curing behavior of SMF.

Summary: In this study, a novel type of hollow hierarchical porous TiO2/Ag composite microsphere with tunable microstructure was successfully prepared. Compared with hollow hierarchical porous TiO2 microspheres, the composite microspheres showed a shift in excitation wavelength towards visible light direction, improved response range and light utilization rate. The optimal addition amount of Ti and Ag resulted in specific surface area of 177 m2/g, pore volume of 0.37 cm3/g, and primary and secondary pore sizes of 4.04 nm and 7.74 nm, respectively. They exhibited the highest photocatalytic activity towards 365 nm and 395 nm ultraviolet light, with degradation rates of methyl orange solution reaching 96.84% and 98.65%, respectively. Their excellent performance was attributed to the unique combination of hierarchical pores and hollow structures, as well as the synergistic effect of Ag and TiO2.
