Strain Engineering of ZrO2@TiO2 Core@shell Nanoparticle Photocatalysts

The development of better photocatalysts through composition- and structure-engineering.

Semiconductor photocatalysts that can effectively utilize solar irradiation hold great potential for harnessing renewable-energy sources, as well as for environmental protection and -remediation. Exploring advanced photocatalysts that have improved performance has been a central theme in photocatalysis research. Herein, we review the recent developments in the design- and fabrication of photoca...

Grain boundary engineering in electrospun ZnO nanostructures as promising photocatalysts

Nanoparticle superlattice engineering with DNA.

A current limitation in nanoparticle superlattice engineering is that the identities of the particles being assembled often determine the structures that can be synthesized. Therefore, specific crystallographic symmetries or lattice parameters can only be achieved using specific nanoparticles as building blocks (and vice versa). We present six design rules that can be used to deliberately prepa...

Engineering of nanoparticle size via electrohydrodynamic jetting

Engineering the physical properties of particles, especially their size, is an important parameter in the fabrication of successful carrier systems for the delivery of therapeutics. Here, various routes were explored for the fabrication of particles in the nanosize regime. It was demonstrated that the use of a charged species and/or solvent with high dielectric constant can influence the size a...

Highly-efficient cocatalyst-free H2-evolution over silica-supported CdS nanoparticle photocatalysts under visible light.

A silica-supported CdS nanoparticle photocatalyst exhibits excellent visible-light driven H2 evolution activity without the use of a cocatalyst. The apparent quantum yield can reach 42% under 420 nm light illumination.
