Summary: In this study, n-p Bi2O2CO3/alpha-Bi2O3 heterojunction microtubes were successfully prepared via a one-step solvothermal route, and Ag nanoparticles were loaded onto the microtubes. The results showed that the carbonatization of alpha-Bi2O3microtubes on the surface led to the formation of a Bi2O2CO3/alpha-Bi2O3 heterostructure. The photocatalytic activity evaluation demonstrated that Bi2O2CO3/alpha-Bi2O3 with a Bi2O2CO3 mass fraction of 6.1% exhibited the highest activity, and loading with Ag nanoparticles significantly enhanced the photocatalytic activity of Bi2O2CO3/alpha-Bi2O3.

Summary: A modified sol-gel process using Pluronic F-127 as the surfactant successfully synthesized bismuth oxide (Bi2O3). By incorporating mesoporous Bi2S3 nanoparticles onto the surface of Bi2O3, heterojunctions that enhance charge transfer and visible light absorption were formed. The content of Bi2S3 determined the effectiveness of the heterojunctions, with 3.0 wt% achieving the best photocatalytic activity for tetracycline degradation.

Summary: The La2Ti2O7/Bi5O7I (LB) composite photocatalyst was synthesized by an in-situ growth method. The optimal photocatalytic efficiency was achieved by the LB-2 composite photocatalyst, showing higher activity than the individual components La2Ti2O7 and Bi5O7I mainly due to the heterojunction formed between them. The charge transfer mechanism and degradation mechanism of CIP were proposed based on data analysis and energy band theory.

Summary: The study suggests that depositing hydrothermally synthesized ZnO onto ZnS-containing industrial waste can significantly enhance UV-light-induced photocurrent. This enhancement is achieved through the formation of a ZnS-IW@ZnO heterojunction. Molecular modeling calculations demonstrate that the incorporation of ZnO promotes the adsorption of water molecules, leading to the formation of a monolayer and further enhancing the effect of the heterojunction.

Summary: Lopinavir and ritonavir, commonly used antiviral drugs for COVID-19, increase in concentration in wastewater and hospital effluents. Conventional treatment plants have low removal efficiency for these drugs. Lopinavir is highly toxic to aquatic organisms, highlighting the need for thorough monitoring and removal. Photolysis and photocatalysis processes can reduce the toxicity of ritonavir-containing water and wastewater.

Summary: This study introduces oxygen vacancies and Pt clusters on the surface of In2O3 to reduce the optimal operating temperature of formaldehyde gas detection and improve its long-term stability. Experimental results confirm that the adsorbed water on the sensor surface is consumed via a chemical reaction between the oxygen vacancies and Pt clusters. Theoretical calculations reveal that the excellent performance of Pt/In2O3-x sensor is due to the electron enrichment from surface oxygen vacancies and the molecular adsorption and activation ability of Pt clusters. The developed sensor shows potential in ultraefficient, low-temperature, highly sensitive, and stable detection of indoor formaldehyde at room temperature.

Summary: An original strategy of heteroatom (P and S) doping was reported to manipulate ORR selectivity of N-doped hollow mesoporous carbon spheres (N-HMCS). Heteroatom doping can modulate the electronic structure and the proportion/configuration of doped N in N-HMCS, as well as regulate the pathway of ORR. The presence of rich-graphitic N sites and electron-rich C-P bond domains in N,P-HMCS act as electron donors, making *OOH more unstable and easier to desorb into H2O2. Conversely, the introduction of highly electronegative S hinders the desorption of *OOH through a strong interaction with the electron-deficient C-S bond domain, leading to the breakage of the O-O bond and promoting four-electron ORR along with the rich-pyridinic N receptor site. The activity and kinetics mechanism of the reaction show a positive correlation with the proportion of graphitic N, indicating that graphitic N is the primary active site with a much faster electron transfer capacity.

Summary: Water is considered an inhibitor of CO oxidation. The practical application of CO oxidation is investigated by coupling Au nanoparticles and defective CuO to form metal-support interactions and oxygen vacancies. The introduction of Au creates new CO adsorption sites, solving the competitive adsorption problem with H2O and O2. The coupling of metal-support interactions and oxygen vacancies enhances the catalyst's ability and oxygen activation and migration. Au-CuO exhibits stable CO oxidation at room temperature under humid conditions. Theoretical calculations confirm the competitive adsorption and the influence of metal-support interactions and oxygen vacancies on catalyst performance, explaining the mechanism of water resistance in CO catalytic oxidation.

Summary: In this study, the photocatalytic activity of bismuth tungstate (Bi2WO6) for the degradation of perfluoroalkyl substances (PFAS) was enhanced by partially substituting Zn2+ for Bi3+ in the crystal lattice. The partial substitution of Zn2+ influenced the crystal structure, optical properties, and morphology of the nanoparticles of Bi2WO6, resulting in enhanced photocatalytic activity. The photodegradation of PFAS was mainly attributed to the photo-excited holes and superoxide radicals generated during the process.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
