Check out our new article published in ACS Langmuir. 😊 In this study, we present a facile preparation method for HfO2 hollow fibers through a unique integration of the sol−gel process and electrospinning technique. Initially, polystyrene(PS)fibers are fabricated by using electro-spinning, followed by dipping in an HfO2 precursor solution, resulting in HfO2-coated PS fibers. Subsequent thermal treatment at 800°C ensures the selective pyrolysis of the PS fibers and complete condensation of the HfO2 precursors, forming HfO2 hollow fibers. Application in the field of filtration, energy storage, and memory devices are expected.

Hot off the press. We are delighted to share our recent article published in the Journal of Materials Chemistry A (JMCA). Materials #RSCMat In this article, we demonstrated a solar energy derived hybrid electrolysis (overall methanol splitting) system using nickel phosphide nanocrystals with some amount of chromium. Our outcomes reveal the change in shape and crystal orientation of nickel phosphide nanocrystals after chromium doping, which favors the thermodynamics of dehydrogenation process in MOR and hydrogen adsorption in HER. Our work opens a new avenues for the design & development of catalysts for energy-efficient electrosynthesis of valuable chemicals coupled with clean hydrogen production.

 Heterojunction (BHJ)-type Organic Solar Cell is two components: p- and n-doped materials. Heterojunction technology (HJT) stands as the leading solution in the solar industry for maximizing efficiency and power output. By merging the superior characteristics of crystalline silicon with the advantages of amorphous silicon thin-film, HJT creates a high-power hybrid cell. However, careful design of the certain materials as third component is required to achieve optimal panchromatic absorption, suitable energy-level offset, balanced electron and hole mobility, and good light-harvesting efficiency.
