Description
技术领域
本发明属于固载化金属酞菁非均相催化剂技术领域,具体涉及一种同步合成与固载法制备的固载化金属酞菁催化剂及其制备和应用方法。
背景技术
金属酞菁化合物具有18个π电子的芳香共轭大环,这种大π键共轭体系结构使其拥有非常稳定的特性,耐酸、耐碱、耐水、耐热、耐光以及耐各种有机溶剂,化学性能稳定。金属酞菁及其衍生物除了具有独特的光、声、电、磁等性能外,还具有优良的催化性能(共轭分子为平面结构,催化反应可在轴向位置发生反应;所含芳香环既是供电子体又是电子受体),可以催化氧化反应、还原反应、分解反应、羰基化反应、脱羧反应、脱卤反应、聚合反应、傅克反应等多种反应,作为催化剂已在催化氧化脱硫、加氢和乙烯基化、苯乙烯液相氧化反应中得到了广泛应用。同时,金属酞菁化合物因其较窄的禁带宽度(2.0 eV),在可见光600‒800nm波段具有较强的吸收,加上金属酞菁本身具有的热稳定性能和化学稳定性能,对环境无毒无害且廉价易得,近年来有文献报道将其作为光催化剂处理水环境中的污染物。但不管作为何种催化反应的催化剂,金属酞菁化合物仍具有易形成二聚体、抗氧化能力差、不易分离回收和易造成二次污染等缺点,因此,金属酞菁化合物的负载化和固载化成为近年研究的热点。
金属酞菁的负载化主要是通过共混和浸渍的方法依靠物理吸附方式分散在载体的内外表面。负载化金属酞菁催化剂较容易制备,但存在着活性组分易流失、催化剂活性受到影响等问题。金属酞菁的固载化指将金属酞菁以共价键或者配位键的形式固载到载体上。与负载化相比,虽然制备较困难,但共价键或者配位键结合较牢固,能够减少催化剂活性组分流失,有效提高金属酞菁催化剂性能。通过键合法固载化金属酞菁催化剂是目前研究较多、具有广阔发展前景的催化剂固载化方法。陈文兴等将锌酞菁以共价键的形式固载在纤维素纤维上, 在可见光照射、氧气为氧化剂条件下, 该固载型锌酞菁催化剂能有效地催化氧化难生物降解的有机污染物苯酚[陈文兴,陈世良,吕慎水,姚玉元,徐敏虹. 负载型酞菁催化剂的制备及其光催化氧化苯酚,中国科学B辑: 化学,2007,37(4): 369~373]。李艳丽等通过共价键的形式制成活性炭纤维固载铁酞菁催化剂,在H2O2存在条件下,该固载化铁酞菁对4-硝基苯酚氧化降解反应表现出较好的催化活性[李艳丽,吕汪洋,郭桥生,等.活性碳纤维负载铁酞菁催化降解4-硝基苯酚,功能材料,2010,41: 246-249]。然而,传统的通过共价键固载的方法是先制备金属酞菁,然后通过金属酞菁上的活性基团与载体上的活性基团之间的化学反应实现金属酞菁在载体上的固载化。此方法受到金属酞菁产率低、提纯困难、在有机溶剂中溶解度低、负载底物在有机溶剂中对金属酞菁的化学键合困难等条件限制,所得催化剂负载量较低,一般不超过5%,限制了其应用范围。
发明内容
本发明针对现有技术中金属酞菁催化剂固载量低、制备过程困难的缺陷,提供:(1)一种聚合物/硅胶杂化材料固载化的金属酞菁催化剂,能在可见光照射下有效降解废水中的有机染料污染物,还能催化氧气氧化苯乙烯;(2)一种固载化金属酞菁催化剂的制备方法,(3)一种固载化金属酞菁催化剂的应用方法。
本发明中所用的杂化材料—聚甲基丙烯酸缩水甘油酯/硅胶(PGMA/SiO2),可以按照文献[章艳,王蕊欣,高保娇. 接枝微粒PGMA/SiO2固载的金属卟啉仿生催化剂的制备[J],化学研究与应用,2008, 20 (6) : 678-685]中所述方法制备,其表面PGMA的接枝度为26%。
本发明中所用的4-(4-羧基苯氧基)邻苯二甲腈(CPPN) 可以按照文献[毛利军.锌酞菁类化合物的合成、结构及性能研究[D]. 中北大学, 2013] 中所述方法制备。
本发明采用如下的技术方案实现:
一种同步合成与固载法制备的固载化金属酞菁催化剂,其结构如通式(I)所示,聚甲基丙烯酸缩水甘油酯/硅胶PGMA/SiO2固载化金属酞菁MPc催化剂MPc-PGMA/SiO2,由微米级二氧化硅和具有催化活性的金属酞菁功能化聚合物组成,其二氧化硅粒子尺寸为90~125μm,金属酞菁功能化聚合物的键合量为0.12~0.15mmol/g,
同步合成与固载法制备的固载化金属酞菁催化剂的制备方法,其步骤如下:
第一步,将1.0-1.2 g杂化材料PGMA/SiO2置于35-40 mL的溶剂中浸泡,充分溶胀后,加入0.30-0.35g 4-(4-羧基苯氧基)邻苯二甲腈(CPPN)和催化剂,在氮气保护下升温至90-110℃,恒温反应8-10h,过滤,无水乙醇和蒸馏水充分洗涤微球,真空干燥,得键合有邻苯二腈的改性微粒CPPN-PGMA/SiO2,
第二步,将1.0-1.2 g CPPN-PGMA/SiO2置于25-30 mL溶剂中浸泡使微粒充分溶胀,然后加入0.5-0.6 g 取代邻苯二甲腈和金属盐,并加入催化剂,氮气保护下回流反应11-13 h,冷却过滤,并用甲醇反复冲洗产物微粒,再依次分别用浓硫酸浸泡和蒸馏水洗至中性,最后用N,N-二甲基甲酰胺微沸,乙醇洗涤,真空干燥,得键合有金属酞菁的固载化金属酞菁催化剂MPc-PGMA/SiO2(M=Co、Fe、Cu或Mn)。
第一步中所述的溶剂为N,N-二甲基甲酰胺或二甲基亚砜,催化剂为NaOH、NaHCO3、Na2CO3或三乙胺,催化剂的用量为CPPN的摩尔量的5-10倍。
第二步中所述的溶剂为正戊醇,金属盐为水合乙酸钴、乙酸亚铁、水合乙酸铜或水合乙酸锰,取代邻苯二甲腈为4-硝基邻苯二甲腈或CPPN,取代邻苯二甲腈和金属盐的摩尔比为2.4-2.7:1,催化剂为1, 8-二氮杂环[5, 4, 0]十一碳-7-烯(DBU),取代邻苯二甲腈和催化剂的比例为0.5-0.6g:2.4-2.6ml。
同步合成与固载法制备的固载化金属酞菁催化剂的应用方法,其步骤如下:在反应釜中,加入苯乙烯2 mL、N,N-二甲基甲酰胺30 mL和固载化金属酞菁催化剂MPc-PGMA/SiO2(M=Co、Fe、Cu或Mn),苯乙烯与固载化金属酞菁催化剂中所含金属酞菁的摩尔比为1195~1330,常压下通入氧气,于95~105℃反应5.5~6.5h,过滤,乙醇洗涤,回收固载化金属酞菁催化剂。
同步合成与固载法制备的固载化金属酞菁催化剂的应用方法,其步骤如下:在50mL的石英管中加入25 mL的 10 mg/L的亚甲基蓝水溶液和0.09-0.1g的CoPc-PGMA/SiO2,将石英管置于光催化反应装置中,石英管距离光源约15 cm,分别以500 W的汞灯和氙灯为光源,在氙灯外面使用滤光片滤掉紫外光,在磁力搅拌下常温进行光催化降解反应30-60min,过滤,水和乙醇洗涤,回收固载化金属酞菁催化剂。
为说明本发明的固载化催化剂MPc-PGMA/SiO2的化学结构,结合附图进一步说明如下:
图1是接枝微粒PGMA/SiO2、键合微粒CPPN-PGMA/SiO2和固体催化剂CoPc-PGMA /SiO2的红外光谱图。在PGMA/SiO2的谱图中,分别在1736 cm-1和908 cm-1处出现了PGMA上酯羰基C=O和其侧链上环氧键的特征振动吸收峰。PGMA/SiO2键合上CPPN后,1601 cm-1处出现苯环的峰,而且908 cm-1处的峰消失,表明环氧基已开环,且在2200 cm-1处出现了C≡N特征吸收峰,这些都表明CPPN成功键合在PGMA/SiO2上了,制得键合微粒CPPN-PGMA/SiO2。在微粒CPPN-PGMA/SiO2表面同步合成与固载酞菁,形成CoPc-PGMA/SiO2后,在1597 cm-1和1533 cm-1等处出现了酞菁环骨架伸缩振动吸收峰,表明在CPPN-PGMA/SiO 2上成功合成了钴酞菁。
图2为键合微粒CPPN-PGMA/SiO2与固体催化剂CoPc-PGMA-SiO2的固体紫外-可见光谱图。从图中清楚地看到,与CPPN-PGMA/SiO2相比,CoPc-PGMA-SiO2的紫外-可见吸收光谱图中在710 nm处出现了钴酞菁的特征吸收峰,是酞菁环a2u (π)向eg (π*)高能跃迁引起的B带,结合红外光谱,进一步说明在PGMA/SiO2上成功合成了钴酞菁。
图3为接枝微粒PGMA/SiO2与固体催化剂CoPc-PGMA/SiO2的热失重谱图。在图中,温度低于100 ℃时,接枝微粒PGMA/SiO2和固体催化剂CoPc-PGMA/SiO2都有微量失重,此现象是由吸附水的挥发失重所引起的。在240℃附近,接枝微粒PGMA/SiO2开始分解,至大约 800℃,接枝微粒PGMA/SiO2分解完毕,总失重约40.5%。而固体催化剂CoPc-PGMA/SiO2于约320℃左右时开始分解,至约 800 ℃分解完毕,总失重约50.5%,经推算,所制备的固体催化剂CoPc-PGMA/SiO2样品其表面CoPc固载量为0.15mmol/g(即11g/g)。
本发明与现有技术相比,其显著优点:(1) 采用本发明方法,能够将金属酞菁直接以共价键结合到载体上,避免金属酞菁的流失,且变均相催化剂为非均相催化剂,不但保留均相催化剂的活性与选择性,还带来了一系列优点,比如,提高了催化剂的热稳定性,便于催化剂从反应介质中的分离,使催化剂得到重复使用等,极大地提升了催化过程的效率;(2)本发明工艺简单,避免常规化学键合方法中需先制备游离金属酞菁过程中金属酞菁的产率低、分离提纯困难等缺点;(3)采用本发明方法金属酞菁的固载量高(达11%)、成本低、所选取的原料来源较为广泛,后处理较为简单,适合于工业化生产。
