Pada penelitian ini dilakukan sintesis nanopartikel TiO2 menggunakan metode sol-gel dengan pelarut air. Pada proses sintesis ditambahkan kitosan dengan konsentrasi 0; 2,5; 5; dan 10% v/v. TiO2hasil sintesis kemudian dikarakterisasi dengan menggunakan SEM, XRD, dan BET  untuk mengetahui morfologi,  struktur kristal, dan karakteristik pori. Selain itu keempat variasi TiO2diaplikasikan sebagai foto elektroda DSSC. Karakterisasi DSSC dilakukan dengan menggunakan solar simulator AM 1,5 untuk mengetahui karakteristik I-V DSSC. Hasil karakterisasi menunjukkan penambahan kitosan pada konsentrasi rendah (2,5% v/v) mengurangi fasa anatase pada kristal  TiO2dan cenderung memperbesar ukuran kristalit. Penambahan kitosan melebihi 5% meningkatkan fasa anatase dan memperkecil ukuran kristalit. Konsentrasi kitosan 2,5% memperkecil luas permukaan spesifik partikel dan volume total pori. Peningkatan konsentrasi kitosan memberi hasil sebaliknya. Performa DSSC terbaik didapat pada TiO2 dengan konsentrasi kitosan 2,5% saat sintesis, dengan Voc = 0,58 V, Jsc = 0,74 mA/cm , dan η = 0,51%.Kata kunci: titanium dioksida, Dye Sensitized Solar Cell, kitosan

Introduction: The utilization of biodiesel as an alternative fuel is turning out to be progressively famous these days because of worldwide energy deficiency. The enthusiasm for utilizing Jatropha as a non-edible oil feedstock is quickly developing. The performance of the base catalyzed methanolysis reaction could be improved by a continuous process through a microreactor in view of the high mass transfer coefficient of this technique. Materials & Methods: Nanozirconium tungstovanadate, which was synthetized using sol-gel preparation method, was utilized in a complementary step for biodiesel production process. The prepared material has an average diameter of 0.066 &µm. Results: First, the NaOH catalyzed methanolysis of Jatropha oil was investigated in a continuous microreactor, and the efficient mixing over different mixers and its impact on the biodiesel yield were studied under varied conditions. Second, the effect of adding the nanocatalyst as a second stage was investigated. Conclusion: The maximum percentage of produced methyl esters from Jatropha oil was 98.1% using a methanol/Jatropha oil molar ratio of 11 within 94 s using 1% NaOH at 60 &°C. The same maximum conversion ratio was recorded with the nanocatalyst via only 0.3% NaOH.
