在400°C, H2/CO=1.5, 2.5 MPa反应条件下, CO转化率为17%, 低碳烯烃选择性达到80%. 他们提出烯酮(CH2CO)是该催化体系的中间体. 这一新路径被称为OX-ZEO. 近期, 该研究团队基于OX-ZEO体系, 设计了ZnCrOx/MOR双功能催化剂, 成功实现了合成气直接高选性制乙烯, 乙烯选择性高达80%[40]. 与此同时, ...
A magneto-trapped carrier effect induced by BaFe12O19 hard-magnetic nanoparticles (NPs) is discovered, which can lower the carrier concentration of n-type Bi2Te2.5Se0.5 matrix by 16%, and increase the Seebeck coefficient by 16%. Meanwhile, BaFe12O19 NPs provide phonon scattering centers and ...
1.Because different units are used in the calculation carried out in China and that carried out outside of China, the unit conversion, which may affect the calculation, is necessary.在自控工程计算中气体温度、压力补偿及常用单位换算是重要的。 英文短句/例句 1.conversion of arc to time角度、时间...
The compressive modulus is 2.4 MPa and the electrical conductivity is 220.3 ± 16.8 S/m when the solid content was 5%. Anisotropic Ti3C2T x MXenes hydrogels facilitate fast water transport within vertical microchannels, bringing a competitive performance in solar steam generation (1.90 kg m−2 ...
