紫外光照射下光催化水還原二氧化碳制取甲醇。此處最好的光催化活性響應(yīng)的釹負(fù)載量是0.2wt.%。8小時紫外光照射后甲醇的收率為184.8μmol/g-cat, Nd/TiO2比純二氧化鈦明顯增強(qiáng)了光催化的性能。
?
Nd/TiO2能使甲醇產(chǎn)率在短的照射時間和無空穴犧牲劑的情況下高達(dá)184.8μimol/g-cat。Ce4+因其f軌道的特殊性增強(qiáng)光催化效率。

Under UV irradiation, photocatalytic water reduction of carbon dioxide to produce methanol. The optimal loading of neodymium for photocatalytic activity response here is 0.2 wt.%. The yield of methanol after 8-hour UV irradiation was 184.8 μ mol/g-cat, Nd/TiO2 significantly enhances the photocatalytic performance compared to pure titanium dioxide.
Nd/TiO2 can achieve a methanol yield of up to 184.8 μ mol/g-cat in a short irradiation time and without hole sacrificial agents. Ce4+enhances photocatalytic efficiency due to its unique f-orbital.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a special chromatographic column for the determination of carbon dioxide to methanol using new technology. With only one packed column and constant temperature operation, the content of carbon monoxide, carbon dioxide, methanol, and water can be easily separated with high column efficiency and good separation.
This column is a characteristic product of Haohan Chromatography
