题目：Photo-catalytic reduction of carbon dioxide with in-situ synthesized CoPc/TiO2 under visible light irradiation 摘要：CO2 is photo-catalytically reduced to produce formic acid, methanol, formaldehyde in an aqueous solution using visible light irradiation and in-situ synthesized CoPc/TiO2. CoPc/TiO2 nano-composite is in-situ synthesized through the annulations of 1,2-dicyanobenzene on the surface of TiO2 with Co(II) as template. The prepared catalysts are characterized by means of XRD, DTA–TG, UV–vis and FT-IR methods. The photo-catalytic activity of these catalysts under visible light is discussed. The experimental results indicate that cobalt-phthalocyanine (CoPc) and TiO2 are indeed synthesized by the in-situ method. Under the visible light irradiation, CoPc molecules are excited first and the excited electrons are injected into the conduction band of TiO2, then the separation of electron–hole pairs is increased so that the photo-catalytic efficiency is increased. The results show that the in-situ CoPc/TiO2 out performed physical absorbed CoPc/TiO2. The total organic carbon (TOC) yield of 0.7 wt.% in-situ CoPc/TiO2 is 1714.9 mmol/ g catal. following 10 h of visible light illumination. The yield is much higher than those of TiO2 and physical absorbed CoPc/TiO2. |

题目：用原位生成的酞菁／TiO2可见光照射下的光催化还原二氧化碳 摘要：光催化还原CO2制取甲酸，甲醇，甲醛在水溶液中使用可见光照射和原位合成的酞菁／TiO2。COPC /二氧化钛纳米复合材料是通过1,2 -二氰基苯对TiO2与CO的表面原位合成了环（II）为模板。所制备的催化剂进行了表征，通过XRD，DTA–TG，紫外可见和红外光谱的方法–。在可见光下的光催化剂的光催化活性进行了讨论。实验结果表明，钴酞菁（酞菁）和TiO2确实是由原位法合成。在可见光照射下，酞菁分子被激发，激发的电子注入到TiO2导带的电子空穴对，然后–分离增加，从而提高了光催化效率。结果表明，原位COPC / TiO2进行物理吸收COPC /二氧化钛。总有机碳（TOC）0.7重量%的原位COPC / TiO2收率为1714.9毫摩尔/克催化剂。在可见光照射的H 10。产量比TiO2和物理吸收COPC / TiO2高得多。 |
