Summary: In this study, NiCo2O4 double-shelled hollow spheres (DHSs) with porous surfaces were successfully synthesized using a self-templating strategy, with a large specific surface area of up to 93.5 m² g⁻¹, outstanding gas permeability, and more reactive sites. The sensitivity and response time of NiCo2O4 DHSs to 100 ppm xylene at the optimal working temperature of 240 degrees C were 23.3 and 15.4 s, respectively.

Summary: Novel Tb-doped TiO2 hollow spheres (HSs) have been synthesized for the first time in the range of 0.0-2.0 at.%, revealing a significant impact of Tb presence and morphology on the anatase-to-rutile transition temperature. Contrary to expectations, Tb doping reduces the transition temperature and favors rutile phase formation in HSs. XPS measurements confirm the presence of Tb3+ and Tb4+ in both HSs and NPs, with Tb4+ contributing to weakened f-f emission intensity and destabilization of the anatase phase.

Summary: RAFT mediated dispersion polymerisation in scCO2 is an efficient method for synthesising block copolymer microparticles with complex internal nanostructures. In this study, phase separated triblock terpolymer microparticles were successfully synthesized using a simple two-pot sequential synthesis procedure, showcasing high monomer conversions and no purification steps. The P4VP block in the microparticles was then utilized as a structure-directing agent for the fabrication of TiO2 microparticles, leading to increased surface area and enhanced photocatalytic efficiencies when compared to traditional porous TiO2 particles.

Summary: In this paper, CdS QDs@ZrO2-TiO2 hollow spherical composites with double Z-scheme heterostructure modified by CdS QDs were prepared. The composites exhibited a hollow sphere structure with uniform size and orderly arrangement. The double Z-scheme heterojunction formed between CdS QDs, ZrO2, and TiO2 in the composite can optimize the charge transfer path and improve the charge separation efficiency. The CdS QDs@ZrO2-TiO2 composites showed superior photocatalytic performance compared to other systems, with high photo catalytic degradation rate and photocatalytic hydrogen production rate under simulated sunlight.
