Summary: Oil spills can cause significant water pollution, and the use of effective oil sorbents is one way to address this issue. Various synthetic sorbents made of graphene, carbon nanotubes, and polymers have been developed, but none of them fully meet the requirements of an ideal oil sorbent. In this study, a super oil sorbent with a porous structure was fabricated using an energy-efficient approach. The sorbent exhibited high oil uptake values, fast uptake kinetics, and sufficient mechanical strength. It also did not require expensive hydrophobic functionalization, resulting in lower energy consumption and carbon footprints.

Summary: This study introduces a facile method utilizing sodium dithionite to control the photoresponse characteristics of oxide semiconductors, leading to the fabrication of a diverse range of optoelectronic devices. The method allows for fine-tuning of photoresponse characteristics by adjusting the molarity of sodium dithionite, demonstrating superior applicability in various applications. The results show that reducing treatment can effectively control the photoresponse of oxide semiconductors without the use of a light absorption layer.

Summary: BiVO4 nanorods were synthesized using V2O5 nanorods as growth templates and vanadium sources. The uniform BiVO4 nanorods were fabricated through the outward diffusion of V2O5 nanorods and the ion-exchange reaction between V2O5 and Bi(NO3)(3). The morphology, crystal phase, and chemical states of the samples were characterized. The V2O5 nanorods were found to have a critical effect on the preparation of BiVO4 nanorods.

Summary: This research introduces two new modified Hummers' methods for pre-oxidizing graphite powder, resulting in increased oxygen functionalities on graphene oxide (GO) layers. Characterization techniques such as XPS, Boehm titration, Raman spectroscopy, XRD, DLS, and zeta potential analysis were utilized to analyze the GO samples. The study demonstrates that the oxidation degree of GO affects the properties of reduced GO (rGO), and the newly synthesized rGO shows potential as a H2O2 sensor electrode.

Summary: Integration of metalloporphyrin moieties into the porous organic polymer (POP) framework via conjugated linkages can enhance the hydrogen evolution reaction (HER) performance. In this study, a porous cobalt porphyrinic network (CoTPP-POP) with benzene linkages was synthesized for water reduction. CoTPP-POP exhibits excellent HER performance with a low overpotential, good long-term durability, and remarkable Faradaic efficiency in acidic medium. The findings demonstrate a facile approach to designing advanced electrocatalysts for energy applications.

Summary: Polymeric carbon nitride (CN), a metal-free semiconductor photoelectrode material, has gained significant attention in the field of photoelectrochemical (PEC) water splitting. By doping boron or phosphor into CN, the resulting films show improved charge injection properties, longer electron lifetime, and reduced flat band potential, leading to higher photocurrent density compared to pure carbon nitride samples.
