Microwave-assisted hydrothermal synthesis of Cu-doped titanate nanotubes: photoluminescence and photocatalysis properties

Manfroi D.C., Andrade L.P., Cavalheiro A.A., Jos A.A., Teixeira G.F., Perazolli L.A., Varela J.A., Zaghete M.A., Universidade Estadual Paulista, BR

Alkali titanates have been intensively investigated mostly because of their properties. And the interest for transition metal doping of 1D titanate nanostructures is enormous, especially copper. In the present work we report the synthesis of [...]

Copper Oxide–Cobalt Oxide Nanoscale Heterostructures for Photocatalysis

Shi W., Chopra N., The University of Alabama, US

The research work discussed here will be focused on development of multifunctional nanoscale heterostructured photocatalysts comprised of oxides of copper and cobalt. Two fabrication approaches are described: a) solution and b) dry processing route. The [...]

Photocatalytic Performance of Cu/TiO2-xNx Nanotube Arrays Enhanced by Surface Plasmon Resonance and Application in Hydrogen Evolution by Water Splitting

Kang L., Liu E., Hu X., Fan J., Fan X., Wu F., Wu H., Fan J., Fan X., Hou W., Wu F., Wu H., Wang Q., Northwest University, CN

Studies revealed that noble metal (Au, Ag, Pd) nanoparticles can improve the photoresponse property of TiO2 in the visible region based on the surface plasmon resonance (SPR) effect, and enhance the activity of TiO2 photocatalyst. [...]

TiO2-based photocatalytic and antimicrobial coatings: comparison between sol-gel and electrodeposited silver/TiO2 nano-composites

Diamanti M.V., Magagnin L., Del Curto B., Candiani G., Pedeferri MP., Politecnico di Milano, IT

Among possible ways to improve air quality in urban atmospheres, the use of nanostructured TiO2 films as photocatalysts is an excellent way to mitigate the problem, although it cannot offer a complete solution. TiO2 also [...]

Integrated Photocatalytic and Microbial Degradation of Kraft Lignin

Shende A., Shende R.V., Hussein M., Bhosale R., Harder-Heinz D., Shende A., Shende R.V., South Dakota School of Mines & Technology, US

Kraft lignin (KL), a waste product of paper and pulp industry is recalcitrant to biochemical degradation. In our attempt to overcome KL recalcitrance, we coupled photoreforming of Kraft lignin (KL) with microbial degradation. It is [...]
