| 1 | Visible light-induced synthesis of biomass-derived quinoxaline by using Co phthalocyanine immobilized on pyridine-doped g-C_(3)N_(4)显示文摘Visible light-driven valorization of biomass has recently been a pioneering field for nitrogen-containing heterocyclics syntheses due to its sustainable features.Herein,various aromatic ring-doped g-C_(3)N_(4) nanosheets(Ar-g-C_(3)N_(4);Ar=Py,Pm,Ph)were precisely designed to modulate their intrinsic electronic and band structure,which involves pyridine(Py),pyrimidine(Pm),and benzene(Ph)-doped g-C_(3)N_(4).Photocatalysts(CoPc/Ar-g-C_(3)N_(4)) of cobalt(II)phthalocyanine(CoPc)-fabricated Ar-g-C_(3)N_(4) were then developed for oxidative cyclization of furoin with 1,2-phenylenediamines for syntheses of various biomass-derived quinoxalines under visible-light irradiation.The catalytic activity(in terms of TOFs)of serial CoPc/Ar-g-C_(3)N_(4) samples increased with their transient photocurrents with CoPc/Py-g-C_(3)N_(4) as the most active one.For CoPc/Py-g-C_(3)N_(4),CoPc species functioned as both sensitizer and catalytic sites;while,doped Py led to a narrowed bandgap energy.Mechanism research further demonstrated that O_(2) was activated to superoxide radical(·O_(2)^(-)) by photoexcited high-level-energy electron(HLEE)transfer from Py-g-C_(3)N_(4) to CoPc for the subsequent aerobic oxidation. | Mingren Jin Seyed Mohsen Sadeghzadeh Jinzhu Chen | 2023 | Journal of Energy Chemistry2023，，7： | 0 |
| 2 | Determination of Photoelastic Constant Ratio of the Two Components in Ge_(x)Si_(1-x)/Si Superlattice显示文摘From the intensity ratio of the folded longitudinal acoustic phonons with respect to the longitudinal acoustic phonon in a Ge_(0.51)Si_(0.49)/Si superlattice(SL),we obtained a photoelastic constant ratio of 6.6 for Ge_(0.51)Si_(0.49) alloy with respect to Si in the SL at wavelength 5145 A,which is 2.6 times greater than that obtainedby[He Phys.Rev.B 39(1989)5919]in a Ge_(0.5)Si_(0.5)/Si SL. | JIN Ying ZHANG Shulin ZHOU Guoliang YU Mingren QIN Guogang | 1992 | Chinese Physics Letters1992，9，4： | 0 |
