Summary: Heterostructured catalysts combining titanium dioxide nanobelts with palladium oxide nanoparticles exhibited enhanced photocatalytic activity for the degradation of phenol and methyl orange. PdO-C-NB showed the highest degradation efficiency among the four catalysts tested, with a 61% degradation rate for phenol within 90 minutes, nearly double that of using NB. The enhanced photocatalytic property of PdO-C-NB was attributed to its large specific surface area, abundant photocatalytic active sites, and low recombination rate of electron-hole pairs.

Summary: A plant biomass mediated ecofriendly synthesis approach was used to design gold nanoparticles (gAuNPs) on reduced graphene oxide (RGO) using Averrhoa carambola leaf extract at room temperature. The combination of folded RGO sheets and polar biomolecules of the leaf extract helped enhance the growth inhibition effect and significantly reduce the size of gAuNPs in the nanocomposite. The synthesized compound was characterized using various techniques including XRD, TEM,STEMHAADF, Raman, FT-IR, and UV-Vis DRS spectra, revealing a size of 8±3 nm for gAuNPs on 2D-RGO sheets. The gAuNPs loaded on RGO exhibited high photocatalytic degradation rates for various pollutants under visible light irradiation.

Summary: Understanding interactions and stability in the gut microbiome is crucial for studying ecological issues in the gut ecosystem. This study examined the assembly and succession of gut microbiota in zebrafish and found that interactions and stability generally increased with fish development. This was attributed to the development of the immune system, increased colonization space, and stability of nutrients in adult zebrafish. Keystone taxa, even with low abundances, played significant roles in affecting interactions and stability. These findings have implications for managing gut microbial stability in fish and other animals.

Summary: Researchers achieved efficient photocatalytic conversion of CO2 to CH4 through a strongly coupled van der Waals heterostructure. The optimized structure, decorated with precious metal Pt, demonstrated a CH4 selectivity of 90.2% and an evolution rate of 11.79 mu mol g-1 h-1 without the need for sacrificial agents. By enabling photoelectron transfer and the presence of separate but cooperative reduction centers, CO2 was converted to CH4. This study offers a new perspective for selective tandem photocatalytic CO2 conversion by designing hybrid photocatalysts with spatially separated but cooperative active centers.

Summary: In this study, atomic-dispersed Sn-modified Cu nanowires (Cu@Sn NWs) were synthesized for selective electrocatalytic CO2 reduction reaction (CO2RR) to CO with an optimized FECO of 96.4%. Moreover, the formaldehyde oxidation half-reaction (FOR) at MnO2/CP anode was introduced to build a novel CO2RR/FOR system, further improving CO2RR efficiency and reducing energy consumption. Compared with the CO2RR/WOR system, the CO2RR/FOR system showed higher CO2RR performance and tunable selectivity of converting formaldehyde to formic acid. Furthermore, the working cell voltage and energy consumption could be significantly reduced over the CO2RR/FOR system, compared to the CO2RR/WOR system.
