Kun Qian,Brendan C. Sweeny,Aaron C. Johnston-Peck,Wenxin Niu,Jeremy O. Graham,Joseph S. DuChene,Jingjing Qiu,Yi-Chung Wang,Mark H. Engelhard,Dong Su,Eric A. Stach,Wei David Wei +11 more
TL;DR: This study clearly demonstrates the essential role played by Au NP size in plasmon-driven H2O reduction and reveals two distinct mechanisms to clarify visible-light photocatalytic activity under different excitation conditions.
Journal ArticleDOI
Large scale photochemical synthesis of M@TiO2 nanocomposites (M = Ag, Pd, Au, Pt) and their optical properties, CO oxidation performance, and antibacterial effect
TL;DR: In this paper, the authors showed that the presence of the TiO2 matrix enhances the antibacterial effect of silver nanoparticles, and the growth of E. coli can be completely inhibited even if the concentration of Ag in Ag@TiO2 nanocomposite is very low (10 μg/mL).
Journal ArticleDOI
Polyvinylpyrrolidone-induced anisotropic growth of gold nanoprisms in plasmon-driven synthesis
Yueming Zhai,Joseph S. DuChene,Yi-Chung Wang,Yi-Chung Wang,Jingjing Qiu,Aaron C. Johnston-Peck,Bo You,Wenxiao Guo,Benedetto DiCiaccio,Kun Qian,Evan Wenbo Zhao,Frances Ooi,Dehong Hu,Dong Su,Eric A. Stach,Zihua Zhu,Wei David Wei +16 more
TL;DR: It is revealed that the surfactant polyvinylpyrrolidone preferentially adsorbs along the nanoprism perimeter and serves as a photochemical relay to direct the anisotropic growth of gold nanoprisms.
Journal ArticleDOI
Influence of Speciation of Aqueous HAuCl4 on the Synthesis, Structure, and Property of Au Colloids
TL;DR: In this article, the pH-dependent speciation of aqueous HAuCl4 and its influences on the synthesis, structure, and property of Au colloids were studied, and it was shown that reduction of HAuCL4 at low pH leads to the synthesis of well-dispersed and uniform fine Au colloid.
Journal ArticleDOI
Bifunctional N-Doped Mesoporous TiO2 Photocatalysts
TL;DR: In this article, a mesoporous N-doped TiO2 (N-TiO2) photocatalysts were obtained by the precipitation of titanyl oxalate complex ([TiO(C2O4)2]2]−) by ammonium hydroxide at a low temperature followed by calcination at different temperatures.
