Heterostructured Tin oxide-pillared tetratitanate with enhanced photocatalytic activity.

Journal of colloid and interface science

Li B, Lin BZ, Zhang O, Fu LM, Liu H, Chen YL, Gao BF.
PMID: 22858048
J Colloid Interface Sci. 2012 Nov 15;386(1):1-8. doi: 10.1016/j.jcis.2012.07.003. Epub 2012 Jul 16.

An effective active heterostructured photocatalyst of porous SnO(2)-pillared tetratitanate nanocomposite is synthesized by assembling tetratitanate nanosheets with SnO(2) nanoparticles via an exfoliation-restacking route. The nanocomposite was characterized by powder X-ray diffraction, high-resolution transmission electron microscope, thermogravimetric analysis, UV-vis DRS,...

Facile synthesis and optical properties of polymer-laced ZnO-Au hybrid nanoparticles.

Nanoscale research letters

Wang X, Zhang X, Cheng W, Shao H, Liu X, Li X, Liu H, Wu J.
PMID: 24606946
Nanoscale Res Lett. 2014 Mar 07;9(1):109. doi: 10.1186/1556-276X-9-109.

Bi-phase dispersible ZnO-Au hybrid nanoparticles were synthesized via one-pot non-aqueous nanoemulsion using the triblock copolymer poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) as the surfactant. The characterization shows that the polymer-laced ZnO-Au nanoparticles are monosized and of high crystallinity and demonstrate excellent...
