Summary: Developing a convenient, fast-response, and high-performance formaldehyde detection sensor is significant but challenging. In this study, various CeO2 phases, facets, and adsorption sites were selected as substrates, and transition metals were doped on CeO2 surfaces. The results showed that the cubic fluorite structure of CeO2 and TM-CeO2(100) (TM = Au, Hf, Nb, Ta, Zr) exhibited superior abilities in adsorbing formaldehyde. The mechanism of TM-doped CeO2 improving the performance of formaldehyde adsorption was clarified using various analysis methods. This work provides theoretical guidance and experimental motivation for the development of novel formaldehyde sensors based on metal oxide semiconductor materials.

Summary: The Cu/CeO2 nanoporous composite material was prepared using a one-step and energy-saving method known as solution combustion synthesis (SCS). The phase composition, surface morphology, and optical characteristics of Cu/CeO2 were investigated. The study found that the SCS products consisted of cubic fluorite CeO2 and Cu. The CeO2 synthesized via SCS exhibited a porous structure due to the generation and escape of gas during the reaction, with mesopores nested in the walls of large pores. XPS analysis revealed an increase in oxygen vacancy concentration in CeO2 with increasing Cu concentration. The presence of Cu greatly enhanced the catalytic activity of CeO2, and the 30 wt% Cu/CeO2 composite material exhibited the highest photocatalytic activity for the degradation of methyl orange (MO), approximately 4.3 times that of pure CeO2. UV-vis diffuse reflectance spectroscopy showed a reduction in the semiconductor band gap with the addition of metallic Cu, leading to enhanced photocatalytic activity. Free radical trapping experiments identified $O-2- and h(+) as the main active species in the photocatalytic degradation of MO. Based on the results, a proposed mechanism for the enhanced photocatalysis of Cu/CeO2 nanomaterials was suggested, involving the porous structure providing more reactive sites and channels for mass transfer, and the presence of metallic Cu improving oxygen vacancy concentration in CeO2 and promoting charge-carrier separation, thereby enhancing the photocatalytic performance of Cu/CeO2.

Summary: This study reports the development of a recyclable dual Z-scheme g-C3N4/BiVO4/CuFe2O4 heterojunction as an efficient photocatalyst for the activation of peroxymonosulfate (PMS) under visible light illumination. The novel photocatalyst exhibited enhanced photocatalytic degradation behavior for levofloxacin (LEV) compared to single-component counterparts. The addition of PMS further improved the removal efficiency, which was attributed to the synergistic effect between photocatalysis and PMS activation.

Summary: In this study, an eggshell-loaded CoFe2O4 catalyst was synthesized using a convenient hydrothermal method. The surface morphology and elemental composition of the composites were investigated. The performance of the CoFe2O4/eggshell-activated peroxymonosulfate (PMS) system was evaluated using florfenicol (FF) as a model pollutant, and the effects of operating parameters and water matrices on FF removal efficiency were studied. The main radicals involved in FF degradation were identified, and a possible mechanism was proposed. It was confirmed that the toxicity of FF was reduced during degradation, and dehalogenation and defluorination reactions were effectively carried out. The prepared CoFe2O4 polyvinylidene fluoride (PVDF) membrane improved material stability and reduced metal precipitation.

Summary: This study prepared nitrogen-doped carbon spheres (NCSs) with superior PMS activation ability from low-cost chitosan via a two-step hydrothermal carbonization pyrolysis method for removing organic pollutants. The hydrothermal carbonization process increased the content of pyridinic N, graphitic N, and sp2-hybridized carbon in NCS, significantly enhancing its catalytic performance and changing the catalytic mechanism from radical-dominant to non-radical-dominant process. The NCS with the highest amount of pyridinic N and C--C showed the best catalytic activity, which was 10.4 times higher than that without hydrothermal carbonization. Pyridinic N and C--C enhanced the SMET process by improving PMS adsorption capacity and facilitating electron transfer.

In this study, a facile hydrothermal method is used to construct a direct Z-scheme CdS/WO3 binary composite for photocatalytic coupled redox reaction, producing H-2 and selectively converting aromatic alcohols into aromatic aldehydes in one pot. The CdS/WO3 binary composite exhibits significantly enhanced performance compared to bare CdS and WO3, attributed to its extended light harvesting range, efficient charge carrier separation rate, and optimized redox capability. The feasibility of converting various aromatic alcohols to aldehydes coupled with H-2 evolution on the CdS/WO3 photocatalyst is demonstrated, along with a proposed reaction mechanism.
