The electrochemical CO2 reduction reaction towards value-added fuel and feedstocks often relies on metal-based catalysts. Organic molecular catalysts, which are more acutely tunable than metal catalysts, are still unable to catalyse CO2 to hydrocarbons under industrially relevant current densities for long...
近日,电子科技大学董帆教授在国际顶级期刊Angewandte Chemie International Edition上发表题为“Crystal plane is not the key factor for CO2-to-methane electrosynthesis on reconstructed Cu2O microparticles”的研究工作。作者采用电化学原位拉曼和原位表面增强红外光谱(SEIRAS)技术,并结合DFT理论计算揭示了原位重构形成的...
此外除了单取代,二取代硫酚底物在该体系中也能很好地兼容。 a) Reaction conditions:1a(0.2 mmol),2(1.5 equiv.), LiOtBu (2.0 equiv.), DMF (2 mL), irradiation by 30 W blue LEDs at room temperature (rt) under CO2(1 ...

All rate models included the reverse water gas shift reaction as the most important side reaction at these reaction conditions. The best agreement was obtained with a rate model based on the stepwise mechanism, where in the rate-determining step methane is decomposed to hydrogen and active carbon...

2016年,Klankermayer等人使用均相催化剂(P3)Ru(TMM) (TMM = trimethylene methane) 和酸催化剂实现了CH3OH溶液中CO2加氢制备DMM (图1(b))。这一反应为CO2资源化利用制柴油替代品提供了思路和基础。随后,Klankermayer等人发现使用廉价...
In addition, tetrafluoroborate (BF4-) and trifluoromethanesulfonate (OTF-) anions play a role in the conversion of CO2 to methanol. 3.3. Effect of temperature and pressure In addition to electrocatalysts and electrolytes, other operating conditions, such as temperature and pressure, influence yield ...
Ce0.96Ru0.04O2 and Ce0.95Ru0.05O2 perform best, converting 55% of CO2 with a 99% selectivity for methane, at a temperature of 450 °C. This is comparable to the best catalysts found previously for this reaction. Ce0.95Ru0.05O2 was characterized by XRD, electron microscopy, BET, XPS, IR...
(M=Rh, Ir). The results show that Rh@d-NC shows the best performance in terms of both activity and stability, which is very favorable for methane production (* + CO2 + 8H+ → C*OOH + 7H+ → CO* + 6H+ → CHO* + 5H+ → CH2O* +...
