[资源] 最新nature material光催化两篇

第一篇讲便宜的光催化剂剂TiO2的,深入解释其带边对齐锐钛矿和金红石混合相的好处。
The most widely used oxide for photocatalytic applications
owing to its low cost and high activity is TiO2. The discovery
of the photolysis of water on the surface of TiO2 in 19721
launched four decades of intensive research into the underlying
chemical and physical processes involved2–5. Despite much
collected evidence, a thoroughly convincing explanation of
why mixed-phase samples of anatase and rutile outperform
the individual polymorphs has remained elusive6. One longstanding
controversy is the energetic alignment of the band
edges of the rutile and anatase polymorphs of TiO2 (ref. 7).
We demonstrate, through a combination of state-of-the-art
materials simulation techniques and X-ray photoemission
experiments, that a type-II, staggered, band alignment of
0.4 eV exists between anatase and rutile with anatase
possessing the higher electron affinity, or work function. Our
results help to explain the robust separation of photoexcited
charge carriers between the two phases and highlight a route
to improved photocatalysts.
第二篇,众所周知铂电极催化昂贵,作者研究WS2的,制作单层薄片高催化活性的exfoliated WS2,增强了电催化活性,说是由于high concentration of the strained metallic 1T (octahedral) phase。
Efficient evolution of hydrogen through electrocatalysis at low overpotentials holds tremendous promise for clean energy.
Hydrogen evolution can be easily achieved by electrolysis at large potentials that can be lowered with expensive platinumbased
catalysts. Replacement of Pt with inexpensive, earth-abundant electrocatalysts would be significantly beneficial for
clean and efficient hydrogen evolution. To this end, promising results have been reported using 2H (trigonal prismatic) XS2
(where XDMo or W) nanoparticles with a high concentration of metallic edges. The key challenges for XS2 are increasing the
number and catalytic activity of active sites. Here we report monolayered nanosheets of chemically exfoliatedWS2 as efficient
catalysts for hydrogen evolution with very low overpotentials. Analyses indicate that the enhanced electrocatalytic activity of
WS2 is associated with the high concentration of the strained metallic 1T (octahedral) phase in the as-exfoliated nanosheets.
Our results suggest that chemically exfoliatedWS2 nanosheets are interesting catalysts for hydrogen evolution.最新nature material光催化两篇
