New Findings in Photoelectrochemicals Described from University of Texas Pan American (Facile and Scalable Synthesis of "Caterpillar-like" ZnO Nanostructures with Enhanced Photoelectrochemical Water-Splitting Effect)

By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Biotechnology have been published. According to news reporting originating from Edinburg, Texas, by NewsRx correspondents, research stated, "In an effort to replace conventional multistep seeding methods to produce multidimensional ZnO nanostructures with high spatial occupancy of nanowires (NWs), a rational and facile synthesis protocol for 'caterpillar-like' branched ZnO nanofibers (BZNs) is reported. This process combined the scalable forcespinning technology with a hydrothermal process to efficiently develop BZNs to substantially enhance surface area and roughness factor."

Our news editors obtained a quote from the research from the University of Texas Pan American, "Specifically, unbranched ZnO nanofibers were first prepared by spinning polyvinylpyrrolidone (PVP)/zinc nitrate hexahydrate (Zn(NO3)(2)center dot 6H(2)O) composite fibers, followed by calcination at 500 degrees C. These fibers were deposited on flat substrates to serve as nonwoven netlike seed sites for hydrothermal growth of ultradense and uniform NW branches to form 'caterpillar-like' BZNs. Their usage as photoanodes in photoelectrochemical water-splitting cells was evaluated, resulting in a photon-to-hydrogen conversion efficiency of 0.165%, an enhancement of 147% when compared to ZnO NW arrays with similar dimensions."

According to the news editors, the research concluded: "An enhanced light-harvesting process coupled with a facile and scalable synthetic procedure is presented."
