Herein, we report a ternary electron donor-acceptor complex photocatalytic system that utilizes O 2 to construct multiple C–O bonds successively in a single-step operation, enabling the facile assembly of alkyl aryl ethers. Mechanistic investigation shows that the ternary aryl halide/2- tert -...
In this synergistic system, photogenerated electrons from a photocatalyst with a higher conduction band (CB) can transfer to another photocatalyst with a lower CB, and subsequently migrate to the surface of MWCNTs. Here, they react with O2 to generate reactive superoxide radicals (O2• −), ...
In and shown in Fig. 6d. The addition, time-resolved photoresponse behavior of the device exhibits an obvious current change (~180 nA) and good stability after a long-time operation with alternated turn-on and turn-off process. The long rsianeusscriplIfmuanodcnpesilsnueeagmnotiddmnmee...
The exact speciation depends on the specific physico-chemical properties of the elements, and the conditions on burnup (as well as isotopic composition of the fuel and neutron flux spectrum), temperature, and oxygen potential under normal operation and accidental conditions. Among those fission ...
Cd-Te-Hg by heating the elements and passing the vapours with a transport gas, which does not react with the vapours, e.g. hydrogen, argon or a mixture thereof, over the substrate, the temperature of the vapours being such as to inhibit binary reactions. In an example hydrogen from a ...
Simultaneously, the method has the advantages of good low-temperature in situ growth repeatability, convenient operation, no further post-treatment, environmental-friendliness and convenience for industrial production.何伟伟李品将李大鹏杨风岭贾会敏赵红晓...
The widespread use of antibiotics in veterinary and medical applications has increased the possibility of water contamination, which causes adverse effects such as increased bacterial resistance in humans and other organisms. This study, investigates the
The mixing on the highest efficiency of ratio of used components in the syn- naproxen degradation under the same operation conditions. The best ratio was achieved (4:8:1) of the ZrO2, TiO2, Fe3O4 compounds. Photocatalyst characterization. The mineralogical analysis of the ...
In spite of the practical importance of DRM, as discussed above, this process has not been industrialized yet due to challenges in the development of robust catalysts that can sustain coke-free operation and high resistance to metal sintering at the operational temperatures (ca. > 700 °C) [2...
In general, the phases contained in the alloy reacted with the nital solution to different degrees thereby resulting in different reliefs. So, the different Conclusions Based on the microstructures and the EDS–SEM analyses of the nine alloys, the phase equilibria at the Zn-rich corner in the ...
