Summary: This study compared the photocatalytic activities of active photocatalysts, including AgBr, ZnO, BiOI, and Cu2O, in the presence of a-MoO3. The results showed that a-MoO3 strongly inhibited the photocatalytic activity of TiO2, BiOI, Cu2O, and ZnO, but had no effect on AgBr. Therefore, a-MoO3 could be an effective inhibitor for evaluating newly explored photocatalysts.

Summary: Nanorod-supported (Pt-Pd)/CeO2 catalysts were synthesized by dealloying Al91.7Ce8 PtXPd0.3-X (X = 0, 0.075, 0.1, 0.15, 0.2, 0.3) alloy ribbons. SEM and TEM characterization showed that the resulting catalysts had interspersed nanorod structures with nanopores. The (Pt-0.1-Pd-0.2)/CeO2 catalyst calcined at 300 degrees C exhibited the highest activity for CO oxidation at a low temperature of 100 degrees C, attributed to its stable framework structure and collaborative effect of the noble Pt and Pd metals.

Summary: The charge state of a catalyst has a significant impact on its catalytic activity. This study focused on molecular electrocatalysts of fullerene C-60 with doped transition metals and investigated the effect of charge state on the cathodic nitrogen reduction reaction and anodic oxygen evolution reaction. The results show that the charge state has a strong influence on the cathodic reaction, while it has a relatively weak effect on the anodic reaction. Furthermore, the study highlights the importance of tailoring a specific charge state for effective catalytic activity.

Summary: This study presents a silicon dielectric metamaterial (SDM) composed of two outer symmetric semi-circular rings and two inner symmetric split-ring resonators (SRRs). The electromagnetic responses of the SDM device in different modes were studied through numerical simulations and experiments. Increasing the structure height of the SDM device resulted in red-shifted resonances and stronger intensities. This study provides a new design strategy for the development of frequency filtering, polarization switching, and resonance modulation characteristics in THz-wave applications.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
