| 中文摘要: |
| 制备了三种皂土固载金属酞菁(ZnPc,CoPc,NiPc),研究了它们在可见光照射下,对CO2还原反应的催化作用.MPc/皂土作为P-型半导体,光照下可产生电子转移得到MPc. .研究结果表明,皂土固载金属酞菁比未固载金属酞菁具有更好的催化性能和重复使用性能,而且与酞菁中心配位的金属对其催化性能有影响,本实验中ZnPc/皂土较好,其负载量为1.0%. |
| 英文摘要: |
| The metal phthalocyanine(MPc) adsorbed bentonite are prepared(MPc/bentonite) and used as photocatalysts for the photoreduction of carbon dioxide(CO_ 2 ). The MPc/bentonite behave as a p-type semiconductor. The irradiation leads to formation of holes(MPc ) and HCOOH by electron transfer. The OH - acts as sacrificial electron donor and scavenges the holes. It is found that the bentonite-supported phthalocyanine are more effective catalysts for CO_ 2 reduction than unsupported metallophthalocyanine. At the same time the central metal of phthalocyanine is important for the photoreduction of CO_ 2 . The yield of 1.0% ZnPc/bentonite catalyst gave the highest value. |
