The oxidative dehydrogenation of propane is an attractive reaction for propylene production, but the overoxidation leads to low selectivity at considerable conversions. Here, we report by oxygen in presence hydrogen chloride. CeO2 was found be efficient catalyst conversion (O2 + HCl). structure-sensitive, and catalytic behavior depended on exposed facet nanocrystals. nanorod exposing {110} {100} facets showed highest activity, whereas nanocube enclosed most selective formation. modification...
To determine the prevalence of dry eye syndrome, analyze relationship between symptoms and signs, identify associated risk factors for syndrome in an elderly Tibetan population at high altitude.A population-based survey was conducted from October 2006 to December 2006. A stratified, clustered, random sampling procedure used select 2632 native people >or=40 years age. Symptoms were assessed by using a 6-item validated questionnaire. Dry diagnosed those subjects having 1 or more often all...
Highly efficient photocatalytic reduction of 4-nitroaniline to p-phenylenediamine over a commercial CdS photocatalyst was observed under visible light irradiation (λ ≥ 420 nm) in water. The conversion and the selectivity were ∼100% ∼98% after 9 min irradiation, respectively. photoreduction efficiency remained above 95% 5th cycle testing. Its activity much higher than those nitrogen-doped TiO2 photocatalysts. Further experimental results revealed that ammonium formate N2 atmosphere...
Tetracyclines are refractory pollutants that cause persistent harm to the environment and human health. Therefore, it is urgently necessary develop methods promote efficient degradation conversion of tetracyclines in wastewater. This report proposes a photobiocatalytic synergistic system involving coupling GeO2/Zn-doped phosphotungstic acid hydrate/TiO2 (GeO2/Zn-HPW/TiO2)-loaded photocatalytic optical hollow fibers (POHFs) an algal-bacterial biofilm. The GeO2/Zn-HPW/TiO2 photocatalyst...
A novel orthorhombic LaCO3OH photocatalyst is synthesized by a facile hydrothermal method. The prepared sample exhibits high photocatalytic activity for hydrogen evolution from aqueous methanol solutions under UV light irradiation, which about 3 times higher than that of anatase TiO2. Mott–Schottky plot shows the VCB −0.87 V vs. RHE at pH 7. Theoretical calculations electronic structures reveal top valence band (VB) and bottom conduction (CB) are mainly composed O 2p La 4f states,...
Abstract An acidic gas is an important basic chemical raw material used for synthesizing fertilizers, insecticides, explosives, dyes, and salts. Alternatively, inorganic gases that leak into the air have harmful effects on human health, infrastructure, cultural relics. Therefore, demand sensors quality monitoring management has continuously increased, enabling development of various sensing technologies. Among them, fiber-optic are promising detection because their excellent in-situ...

Abstract Microorganisms can colonize stone surfaces and metabolize them to produce pigments corrosive products, thus causing the weathering of cultural relics. Herein, we show that caused by a representative microorganism ( Scenedesmus obliquus ) be prevented coating with films comprising semiconducting photocatalytic nanocomposite, BiVO 4 /Ti 2 NT x -TiO . The compositing (a narrow-bandgap semiconductor) Ti -doped TiO two-dimensional layered results in an extended visible light absorption...
Mosses are one of the most widespread and dominant biological diseases that damage stone cultural relics. This has resulted in discoloration, cracking, even collapse rocks, which have severely impacted inheritance outstanding traditional cultures. The basis effective preventive conservation is to determine nondestructive accurate detection key parameters related development on Therefore, detect moss coverage rate growth rate, we constructed a semantic segmentation model for rock surfaces....
Photoelectrochemical (PEC) water splitting is gaining recognition as an effective method for producing green hydrogen. However, the absence of in situ, continuous decoding hydrogen generation tools hampers a detailed understanding physics and chemistry involved within PEC systems. In this article, we present quantitative, spatiotemporally resolved optical sensor employing fiber Bragg grating (FBG) to probe formation temperature characteristics system. Demonstrating principle, observed...
