Abstract

Penelitian yang berjudul studi pengaruh temperatur solvotermal terhadap pembentukan struktur Fe3(PO4)2 yang bertujuan untuk mengetahui struktur Fe3(PO4)2 yang disintesis melalui metode solvotermal dan pengaruh variasi temperatur pemanasan yang diberikan. Proses sintesis material menggunakan bahan baku Sodium Dodecyl Sulfate (Nac12H25SO4), Asam Phospat (H3PO4), Urea (CH4N2O) dan Ammonium Ferrous Sulfate Hexahydrate ((NH4)2Fe(SO4)2•6H2O). Pada penelitian digunakan 3 variasi temperatur pemanasan yaitu temperatur 100̊C, 150̊C, dan 200̊C. Dari penelitian didapatkan hasil semakin tinggi temperatur yang digunakan semakin sedikit jumlah pengotor(fasa sekunder) yang muncul pada sampel. Ukuran partikel yang terbentuk pada sampel mengalami peningkatan berbanding lurus dengan temperatur, pada 100̊C dihasilkan partikel berukuran 617nm, 150̊C beukuran 805nm, dan pada 200̊C berukuran 994nm. Terbentuknya morfologi permukaan yang berbeda pada setiap temperatur, pada variasi 100̊C sampel memiliki bentuk menyerupai serpihan, kemudian pada 150̊C sampel berbentuk bongkahan, sedangkan pada 200̊C dihasilkan sampel berbentuk oval. Energy band gap setiap sampel memiliki nilai yang berbeda, pada variasi 100̊C dihasilkan energy band gap sebesar ~0,97eV, 150̊C sebesar ~0,7eV dan 200̊C sebesar ~0,31eV yang menunjukkan terjadinya penyempitan energy band gap seiring dengan meningkatnya temperatur yang digunakan. ==================================================================================================== The study entitled the study of the effect of solvotermal temperature on the structure of Fe3(PO4)2 which aims to determine the structure of Fe3(PO4)2 synthesized by the solvothermal method and the effect of variations in the given heating temperature. The material synthesis process uses Sodium Dodecyl Sulfate (NaC12H25SO4), Phosphoric Acid (H3PO4), Urea (CH4N2O) and Ammonium Ferrous Sulfate Hexahydrate ((NH4)2Fe(SO4)2•6H2O). In this study, three variations of heating temperature were used, namely temperatures of 100̊C, 150̊C, and 200̊C. From the research, it was found that the higher the temperature used, the less the amount of impurities (secondary phase) that appeared in the sample. The size of the particles formed in the sample increases in direct proportion to the temperature, at 100̊C the resulting particles are 617nm, 150̊C are 805nm, and 200̊C are 994nm. The formation of different surface morphology at each temperature, at variations of 100̊C the sample has a shape resembling a flakes, then at 150̊C the sample form like a lump, while at 200̊C the sample is oval. The energy band gap of each sample value is produced, at variations of 100̊C the energy band gap is ~0,97eV, 150̊C is ~0,7eV and 200̊C is ~0,31eV which indicates that the energy band gap is decrease with increased temperature.
