1)SnS2具有较强且均匀分布的Sn-S键,能够有效抑制S溢出,形成有利于CO2RR的Sn/SnS2异质界面;而SnS的Sn-S键强较弱,导致其在CO2RR过程中快速还原成惰性金属Sn。而具有混合键强的Sn2S3则从最弱的Sn-S键开始断裂,引发了更加快速的组分还原,表现出较差的CO2RR性能。 2)SnS2表现出最高的甲酸盐法拉第效率93.8%±0...
Herein we develop a proton-exchange membrane system that reduces CO2 to formic acid at a catalyst that is derived from waste lead–acid batteries and in which a lattice carbon activation mechanism contributes. When coupling CO2 reduction with hydrogen oxidation, formic acid is produced with over ...
The number of lags is chosen to cover the relevant, informative observations of the past, which may also be pertinent considering the degree of freedom. When the lags are added, the degree of freedom decreases directly with the addition of the lags. Thus, to assess the statistical significance...
Interaction of ethynyliron (FpC.tplbond.CH and Fp*C.tplbond.CH) and ethynediyldiiron complexes (Fp*C.tplbond.CFp*) with Co2(CO)8: formation of a cluster compound which is fluxional via a metal-metal bond scission and recombination process ...
Fly ash is the by-product of coal combustion, which accounts for about 60%–88% of the total combustion residues in coal-fired power plants. About 0.75–1 billion tons of fly ash are produced every year globally [52]. However, the global average utilization rate is still below 30% [53...
and 552 mV at 10 and 50 mA ∙cm −2, respectively. Detailed physical characterization and electrochemical tests demonstrated that CoMn1O exhibited over four times the stability of Mn-free Co 3O 4 (CoMn 0O). This enhanced stability can be attributed to the introduction of Mn, which ...
and lnXCO2COSMO−RS is 32.2%, and the prediction is higher than the experimental result as shown in Fig. 1a. This may because the formation of nanoscopic structures in ILs [79,80], which is different from the solvation properties of molecular solutes at the microscopic scale [21]. From ...
Since the energy barrier for the dissociation of the second C-O bond of CO2 on single-atom sites is very high, these catalysts can give high selectivities toward CO or formate products. Thanks to SACs, the conversion of CO2 has become much easier in various chemical environments. 展开 ...
重庆大学重庆大学硕士学位论文英文摘要 PAGE PAGE VI ABSTRACT -The carbonic anhydrase (CA) can effectively catalyze the reversible hydration reaction of CO2 to HCO3 , which is one of the highest catalytic rates of all known CO2 hydration enzymes. Applying CA enzyme to CO2 catalytic absorption can ...
which conditions the RWGS and CO2methanation reactions are also thermodynamically favorable. Cu/ZnO/Al2O3is an industrial catalyst for traditional methanol synthesis from syngas (CO + H2). This catalyst is also applied to methanol synthesis from CO2hydrogenation. However, Cu/ZnO/Al2O3is also...
