Summary: In this study, a [bmim][Tf2N] loaded self-doped TiO2 nanotubes (ILs-RTNTs) composite photocatalyst was developed for the photoreduction of CO2 to acetic acid. The acetic acid yield of ILs-RTNTs reached as high as 88.1 mu mol gcat - 1h- 1,and there was no decrease after six cycles. Both the defects constructed by self-doping and the surface modification by ionic liquids strengthened the light utilization ability of the photocatalyst and enhanced the separation of photoinduced electron-hole pairs. Density-functional theory (DFT) calculations further revealed that the surface loading of ionic liquids introduced more active sites, strengthened the adsorption of CO2, changed the electronic structure, and lowered the energy barrier for electron transfer of the photocatalyst. This study will promote the versatile application of ionic liquids in the field of simultaneous capture and photoreduction of CO2.

Summary: A novel spinel-structured LaFe2O4 demonstrated high ORR electro-catalytic activity through a self-doping strategy. It showed excellent ORR activity in a PCFC at temperatures ranging from 350 to 500 degrees C. The high activity was attributed to the easy release of oxide and proton ions and improved synergistic incorporation abilities of multivalent Fe3+/Fe2+ and La3+ ions. A fuel cell using LaFe2O4 as a cathode achieved a high-power density of 806 mW/cm2 at 500 degrees C. Spectroscopic and calculations methods were used to screen the potential application of LaFe2O4 as a cathode material.

Summary: This study focuses on designing a Co/Fe-SrTiO3 semiconductor perovskite as an electrolyte membrane to enhance its ionic conduction. Through surface-enriched O-vacancies, the doped Co/Fe lowers the Fermi level, leading to improved ionic conductivity. The designed electrolyte exhibits high ionic conductivity (0.19 S/cm) and enables a fuel cell to achieve a maximum power density of 1016 mW/cm2 at 520 degrees C. The surface doping of Co/Fe facilitates enriched surface channels for quick ion transportation with lower activation energy, making it a suitable approach for developing advanced materials for wide bandgap semiconductors with high ionic conductivity for next-generation CFCs.

Summary: Heavy metals, resulting from human activities, are widely present in water bodies and accumulate in the body over time, posing serious health problems. Therefore, improving the sensing performance of electrochemical sensors for the detection of heavy metal ions (HMIs) is crucial. In this study, a cobalt-derived metal-organic framework (ZIF-67) was synthesized and incorporated onto the surface of graphene oxide (GO) using a simple sonication method. The synthesized material (ZIF-67/GO) was characterized and used to create a sensing platform for the individual and simultaneous detection of heavy metal ion pollutants (Hg2+, Zn2+, Pb2+, and Cr3+), with detection limits below the permissible limit set by the World Health Organization. This is the first report of HMIs detection using a ZIF-67 incorporated GO sensor, which can successfully determine Hg+2, Zn+2, Pb+2, and Cr+3 ions simultaneously with lower detection limits.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
