Summary: In this study, self-supported Co3N nanowire arrays with different Mo doping contents were synthesized by hydrothermal and nitridation processes, and they exhibited robust electrocatalytic activity for overall water splitting. The optimal Co3N-Mo-0.2/Ni foam electrode showed a low overpotential of 97 mV at a current density of 50 mA cm(-2) for the hydrogen evolution reaction. Theoretical calculations confirmed that Mo doping could effectively modulate the electronic structure and surface adsorption energies of Co3N, leading to improved reaction kinetics and catalytic activity.

Summary: The removal of refractory contaminants such as tetracycline antibiotics from wastewater has attracted significant attention. In this study, semi-ionic mesoporous F-doped g-C3N4 photocatalysts with different doping amounts were successfully fabricated. Among them, GCN-F0.50 exhibited the highest TC removal performance under visible light irradiation, achieving a removal rate of 99.8% (0.0207 min(-1)) in 180 min. Furthermore, GCN-F0.50 showed a COD removal rate of 75.9% for TC, attributed to the high polarity of the semi-ionic C-F bond.

Summary: Metal geometrical structure engineering of composite catalysts is powerful to enhance their photocatalytic performance. By loading transition metal phosphides (TMPs) on P doped g-C3N4 (PCN), catalytic performance of TMPs/PCN is optimized and a geometry-site-dependent photocatalytic hydrogen evolution is determined. Tri-metallic FeCoNiP/PCN catalysts with high occupancy of tetrahedral cobalt sites show superior photocatalytic activity compared to mono-metallic and bi-metallic TMPs/PCN, as well as Pt/b-g-C3N4 and Pt/PCN.

Summary: A two-step method was used to prepare B-doped g-C3N4 nanosheets. The multi-layer porous morphology increases the transmission pathway of visible light, enhancing its capture ability. B doping decreases the bandgap and increases the sensitivity of g-C3N4 to visible light. The best performing photocatalyst for nitrogen fixation was found to be 2 wt% B/g-C3N4, which exhibited a nitrogen fixation efficiency 2.44 times higher than g-C3N4 (81.56 mol/L-1.h-1 vs 33.52 mol/L-1.h-1). Additionally, 2 wt% B/g-C3N4 showed strong photocatalytic stability.

Summary: Loading co-catalysts effectively enhances the photocatalytic activity by breaking the confinement of bulk carbon nitride. In this study, N-doped g-C3N4 decorated with CoSx was synthesized through a photochemical route. The optimized hydrogen evolution rate of N-CN-CoSx-4 was 1757 μmol g(-1)h(-1) under visible light irradiation. The enhanced photocatalytic activity of N-CN-CoSx-4 can be attributed to its superior interfacial carrier transfer properties and improved light absorption. This research provides a reference for the development of high-efficiency, stable, and affordable photocatalysts.

Summary: The performance of the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) were enhanced by synthesizing the BiOI/graphitic carbon nitride nanotubes (g-C3N4 nanotubes) heterojunction. The stable heterojunction prevented rapid recombination between photoexcited electrons and holes, resulting in optimized electronic transmission pathway and faster surface reaction rates. Additionally, the composite exhibited outstanding OER and HER activities under illuminated conditions.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
