Surface modification of ZnO nanocrystals

Nano-crystalline ZnO particles were synthesized using alcoholic solutions of zinc acetate dihydrate through a colloidal process. Five types of capping agents: 3-aminopropyl trimethoxysilane (Am), tetraethyl orthosilicate (TEOS), mercaptosuccinic acid (Ms), 3-mercaptopropyl trimethoxysilane (Mp) and polyvinylpyrrolidone (Pv) were added at the first ZnO precipitation time (first PPT) to limit the...

Analysis and design principles for shear-mode piezoelectric energy harvesting with ZnO nanoribbons

A comprehensive theory addresses the potential for nanoscale energy harvesting with an array of vertically aligned zinc oxide (ZnO) nanoribbons. Through shear-mode piezoelectric coupling, the nanoribbons are capable of generating electricity from elastic deformations induced by sliding friction or mechanical vibration. In contrast to current ZnO nanowire generators, nanoribbons exhibit a unique...

Heteroepitaxial growth of ZnO branches selectively on TiO2 nanorod tips with improved light harvesting performance.

A seeded heteroepitaxial growth of ZnO nanorods selectively on TiO(2) nanorod tips was achieved by restricting crystal growth on highly hydrophobic TiO(2) nanorod film surfaces. Intriguing light harvesting performance and efficient charge transport efficiency has been found, which suggest potential applications in photovoltaics and optoelectronics.

Flexible piezoelectric nanogenerators based on fiber/ ZnO nanowires/ paper hybrid structure for energy harvesting

We present a novel, low-cost approach to fabricate flexible piezoelectric nanogenerators (NGs) consisting of ZnO nanowires (NWs) on carbon fibers and foldable Au-coated ZnO NWs on paper. By using such designed structure of the NGs, the radial ZnO NWs on a cylindrical fiber can be utilized fully and the electric output of NG is improved. The electric output behavior of the NGs can be optionally ...

Complete surface coverage of ZnO nanorod arrays by pulsed electrodeposited CuInS2 for visible light energy conversion.

Well-aligned ZnO nanorods were uniformly coated with a layer of CuInS2 nanoparticle photosensitizers using a tailored sequential pulsed electrodeposition. The formation of CuInS2-ZnO heterojunction with well-matched band energy alignment and the superior electron mobility in ZnO nanorods led to a remarkable 3.75 times improved photoelectrochemical performance of the electrode under visible ligh...
