In situ TPR removal: a generic method for fabricating tubular array devices with mechanical and structural soundness, and functional robustness on various substrates

Highly efficient visible-light driven photocatalysts: a case of zinc stannate based nanocrystal assemblies

“…In this work, the populated visible defect energy states have been conrmed to be responsible for their visible-light driven catalytic activities. Considering the tunability of defect states and concentration, controllability of crystallinity, and possible heterojunction induced synergistic effect, 6,[42][43][44] the DZS-SnO 2 composite has been chosen for further exploration of their photocatalytic behavior. As a control strategy, post-thermal treatment was found to enable further controlled DZS-SnO 2 composites with tunable catalytic performance.…”

Nanostructured cerium oxide: preparation, characterization, and application in energy and environmental catalysis

“…[132] In the past few decades, ceria has been promised as a good candidate material for oxygen and water vapor gas sensors. [133][134][135][136] Barreca et al reported a simple catalyst-free chemical vapor deposition process for preparation of supported columnar ceria nanostructures at low temperature (623 K), as shown in Fig. 14(i).…”

Hierarchically nanostructured materials for sustainable environmental applications

“…The solution in this case therefore, lies in the removal of ZnO after the deposition of perovskite. We recently proposed temperature-programmed hydrogen reducing (TPR) method to successfully remove the ZnO interior in the hierarchical composite nanowires leaving perovskite nanotube arrays on the substrate (Zhang et al, 2012a ). The reducing temperature of ZnO is determined to be 550°C which is far lower than that of the perovskite.…”
