The adsorption properties of CO2 and O2 on SiC nanosheets were fully investigated using the density functional theory method. CO2 molecule always acted as an acceptor regardless the existence of pre-adsorbed O2 on SiC nanosheet surface and attracted electrons from its surface. Theoretical results ...
本研究通过桥接氧原子连接还原性{CuI8}和氧化性{PMo8V6O42}簇,构建了一种晶体整体反应催化剂RO-4,使光生成的电子在氧化还原簇之间轻松转移。在光照射下,RO-4可以实现高效的人工光合作用,其CO生成活性高达20.06 μmol g-1h-1(选择性大于99.5%),同时释放出O2。...
高阻隔性能的NR/BR/pVTPR可以灵活调控pVTPR的交联密度,将半径较小的CO2与半径较大的N2、O2进行分离,使复合材料表现出出色的CO2选择性。随着pVTPR的交联密度增加,选择性逐渐提高,最后CO2/O2选择性达到了26.12,CO2/N2选择性达到了61.4...
All the calculations below are initially considered at sea level and atmospheric pressure. The densities of air and\({\mathrm{CO}}_{2}\)are 1.225 and\(1.98 \, \mathrm{kg}/{\mathrm{m}}^{3}\)at 20 °C, respectively. The density of the air and CO2mixture is computed as follows86: ...
(Supplementary Fig.16). In the presence of 50 mM HMF, the onset potentials for HMFOR are 1.30, 1.37, and 1.41 V for InOOH-OV, InOOH, and InOOH-O2, respectively. The potential needed to attain current density of 10 mA cm−2is 1.34 V for InOOH-OVelectrode, much ...
Both METs were operated in a three-electrode configuration with a potentiostat that monitored the current density and poised a cathode potential of − 0.8 V vs. Standard Hydrogen Electrode (SHE) to promote H2 production [27]. An Ag/AgCl electrode (+0.197 V vs. SHE, model SE11-S ...
where w is the fluctuation in vertical wind speed, C is the molar density of CO2 in air, ı13C (‰) is the stable isotopic composition of CO2 in air relative to a standard (Vienna PeeDee Belemnite), and (ı13C *C) is the fluctuation in the product of C and ı13C. Iso...
式中O2 也可能直接参与腐蚀,发生反应: 对于13Cr 不锈钢来说,在该环境下腐蚀一段时间后,会在局部表面膜薄弱区域发生点蚀,而在腐蚀坑附近也会附着较多的腐蚀产物。13Cr 基体中的 Fe、Cr 会失去电子进入溶液中,同时在腐蚀坑周围进行富集,形成具有一定...

A conceptual depiction of the emissions scaling protocol used to produce GCP-GridFED as described in section 2.2. Descriptions of the input datasets are provided in section 2.1. This figure does not depict the procedure used to calculate emissions uncertainty or O2combustion; however, the figure in...
