Hanoi University of Science and Technology who enthusiastically guided, taught and helped me during the process of studying, researching and completing this thesis I also would like to thank Prof Dr Le Minh Thang and ROHAN Project - Rostock Hanoi DAAD SDG Graduate School and all colleagues at Technical Chemistry Group, University of Rostock for supporting and creating favourable conditions for me to attend the Master Research Exchange Program at the Institute for Chemistry, University Rostock, Germany Finally, my great gratitude is for my family and my friends who always believed and encouraged me so much during my years of study This achievement would not have been possible without them Author, Duong Nguyen Thi Thuy ABBREVIATION ABS Absorbance PMRs Photocatalytic membrane reactors MB Methylene blue XRD X-Ray Diffraction RC Regenerated Cellulose ICP-MS Inductively coupled plasma mass spectrometry UV Ultraviolet VIS Visible MW Molecular weight SPR Surface Plasmon Resonance PTFE Poly Tetra Fluorethylene TiO2 Titanium dioxide Au/TiO2 Gold nanoparticles deposited on titanium dioxide TABLE OF CONTENTS DECLARATION IN LIEU OF OATH .1 ACKNOWLEDGEMENT ABBREVIATION .3 TABLE OF CONTENTS TABLE OF FIGURES TABLE OF TABLES INTRODUCTION .8 Chapter Literature Review 10 Introduction about photocatalyst .10 1.1 Overview of photocatalyst 10 1.2 Introduction about titanium dioxide 11 1.3 Gold nanoparticle supported on titanium dioxide (Au/TiO2) .14 Photocatalytic membrane reactor 17 2.1 Definition .17 2.2 Research works on photocatalytic membrane reactor 18 Researches and application of Au/TiO2 in water treatment 23 Organic pollutant status .24 Chapter Experimental section .26 Experimental overview 26 1.1 Experiment process .26 1.2 Chemical and materials .28 Methods .29 2.1 Synthesis of Au/TiO2 photocatalyst 29 2.1.1 Synthesis method 29 2.1.2 Au/TiO2 characteristic analysis method 30 2.2 Coating photocatalyst into membrane surface 31 2.3 Design and construction of a PMR reactor 33 2.4 Evaluation of the system in removal of organic matter from feed water 34 2.4.1 Evaluation of batch reaction .34 2.4.2 Evaluation of suspended reaction .35 2.4.3 Evaluation of immobilized system 36 Chapter Results and Discussion 37 Characteristics of photocatalyst: 37 Coating Au/TiO2 on membrane surface 38 Evaluation of photocatalyst in batch reaction 39 Evaluation of suspended PMR 40 Evaluation of immobilized PMR .43 CONCLUSIONS .46 RECOMMENDATION 47 REFERENCES 48 ANNEX .51 TABLE OF FIGURES Figure Crystal structure of titanium dioxide phases of rutile, brookite and anatase (Janzeer, 2013) .12 Figure Mechanism of photocatalytic reaction (Xu, Rangaiah, & Zhao, 2014) 13 Figure Comparison between TiO2 and Au/TiO2 reaction .16 Figure The number of publications on the topic of PMR and PMR for water treatment (Zheng et al., 2015) 19 Figure Annual average BOD content in major rivers in Vietnam (2005-2009) 25 Figure Process of study experiment 28 Figure Diagram of Au/TiO2 synthesis process .30 Figure Spraying Au nanoparticles on membrane surface .32 Figure Schematic diagram of a lab-scale PMR system 33 Figure 10 Schematic diagram of (a) tangential (cross) flow filtration and (b) dead– end filtration (El–Safty & Hoa, 2012) 36 Figure 11 UV-VIS absorbance of Au/TiO2 photocatalyst .37 Figure 12 Performance of Photocatalyst in different concentration 40 Figure 13 Performance of different membrane MW at different amount of Au/TiO 41 Figure 14 Performance during the reaction time .42 Figure 15 Performance of different filtration mode in continuous flow 43 TABLE OF TABLES Table Classification of PMRs configuration 19 Table Advantages and disadvantages of different configurations of PMR 21 Table Experiments description 26 Table ICP result of Au/TiO2 sample 38 Table Mass of Au/TiO2 coated in membrane surface 38 Table Solutions used to avoid photo catalysts peeling off the membrane 44
