Black TiO2 nanotubes formed by high energy proton implantation show noble-metal-co-catalyst free photocatalytic H2-evolution
Ning Liu, Volker Häublein, Xuemei Zhou +8
We apply high-energy proton ion-implantation to modify TiO2 nanotubes selectively at their tops. In the proton-implanted region we observe the creation of intrinsic co-catalytic ce…
Hydrogenated anatase: Strong photocatalytic H2 evolution without the use of a co-catalyst
Ning Liu, Christopher Schneider, Detlef Freitag +8
In the present work we show, how a high pressure hydrogenation of commercial anatase or anatase/rutile powder can create a photocatalyst for hydrogen evolution that is highly effec…
muSR Investigation of magnetically ordered states in A-site ordered perovskite manganites RBaMn2O6 (R = Y and La)
Y. Kawasaki, T. Minami, M. Izumi +9
The magnetically ordered states of the A-site ordered perovskite manganites LaBaMn2O6 and YBaMn2O6 have been investigated by muon spin relaxation in zero external magnetic field. O…
Stabilization of charge and orbital ordered states by antiferromagnetism in the A-site ordered YBaMn2O6
X. N. Zhang, K. -Y. Choi, P. Lemmens +2
We report on Raman scattering measurements of the A-site ordered YBaMn2O6 in the wide temperature range of 10-650K. Upon cooling almost all phonon modes show pronounced temperature…
Phase Separation in A-site Ordered Perovskite Manganite LaBaMnO Probed by La and Mn NMR
Y. Kawasaki, T. Minami, Y. Kishimoto +5
La- and Mn-NMR spectra demonstrate that the ground state of the A-site ordered perovskite manganite LaBaMnO is a spatial mixture of the ferromagnetic (FM) an…
A-site Randomness Effect on Structural and Physical Properties of Ba-based Perovskite Manganites
T. Nakajima, H. Yoshizawa, Y. Ueda
The discovery of novel structural and physical properties in the -site ordered manganite BaMnO ( = Y and rare earth elements) has demanded new comprehension ab…
