Abstract

Glukosa merupakan salah satu biomassa yang sangat mudah ditemukan dan bersifat ramah lingkungan serta dapat dikonversi menjadi energi listrik dan senyawa turunan lain melalui proses oksidasi pada glucose fuel cell dengan melibatkan reaksi fotoelektrokimia atas bantuan cahaya. Kombinasi antara glukosa dan perovskite CsPbBr3 pada glucose fuel cell diyakini dapat meningkatkan performa reaksi fotoelektrokimia sebab perovskite CsPbBr3 memiliki properti optik dan properti elektrokimia yang baik. Penelitian ini dilakukan dengan tujuan menganalisis pengaruh perubahan morfologi dari heat treatment perovskite pada berbagai konsentrasi glukosa terhadap sifat optik fotoanoda serta performa oksidasi glukosa dan produksi arus dalam sistem glucose fuel cell. Melalui eksperimen, penelitian ini dilakukan dengan sintesis CsPbBr3 melalui Ligan-Assisted Reprecipitation Process (LARP) yang selanjutnya diberi perlakuan heating treatment pada kondisi tanpa perlakuan, 90℃, dan 110℃ kemudian di-dropcasting sehingga terbentuk fotoanoda FTO/TiO2/CsPbBr3. Pengujian PL dan UV-Vis dilakukan untuk mengetahui properti optik dari CsPbBr3 serta SEM dan XRD untuk mengetahui pengaruh temperatur heating treatment terhadap morfologi material. Hasil menunjukkan bahwa seiring peningkatan temperatur, terbentuk struktur baru berupa CsPb2Br5 serta Cs4PbBr6 akibat penggabungan antarpartikel yang meningkatkan ukuran partikel dan hal ini berakibat pada terjadinya penurunan band-gap energy dan peningkatan wavelength sehingga mengurangi sifat photoluminescence. Performa fotoelektrokimia dan oksidasi glukosa dianalisis melalui uji CV dan LSV pada berbagai konsentrasi glukosa yaitu 0 M; 0,1 M; dan 0,3 M dalam 0,5 M KOH dilanjutkan dengan pengujian GC dan FTIR untuk mengidentifikasi produk turunan yang dihasilkan dari oksidasi glukosa. CH4 serta butyric acid ditemukan sebagai produk hasil oksidasi glukosa dalam fotoelektrokimia dengan proses paling optimal berada pada kondisi tanpa perlakuan dengan glukosa 0,3 M pada potensial 0,3 V.

Glucose is an abundant biomass that is environmentally friendly and can be converted into electrical energy and other derivative compounds through an oxidation process in a glucose fuel cell by photoelectrochemical reactions with the help of light. The combination of glucose and CsPbBr3 perovskite in a glucose fuel cell is believed to improve the performance of photoelectrochemical reactions because CsPbBr3 perovskite has good optical properties and electrochemical properties. This research was carried out to analyze the effect of morphological changes from perovskite heat treatment at various glucose concentrations on the optical properties of the photoanode and the glucose oxidation and current production performance in the glucose fuel cell system. Through experiments, this research was carried out by synthesizing CsPbBr3 via the Ligand-Assisted Reprecipitation Process (LARP) which was then given heating treatment at without treatment condition, 90℃, and 110℃. Through experiments, this research was carried out by synthesizing CsPbBr3 through the Ligand-Assisted Reprecipitation Process (LARP) which was then given heating treatment at temperatures of 25℃, 90℃, and 110℃ then drop casted to form an FTO/TiO2/CsPbBr3 photoanode. PL and UV-Vis tests were carried out to determine the optical properties of CsPbBr3 as well as SEM and XRD to determine the effect of heating treatment temperature on material morphology. The results show that as the temperature increases, new structures are formed in the form of CsPb2Br5 and Cs4PbBr6 due to interparticle mergers which increase the particle size and result in a decrease in band-gap energy and an increase in wavelength, thereby reducing the photoluminescence properties. Photoelectrochemical performance and glucose oxidation were analyzed through CV and LSV tests at various glucose concentrations; 0 M; 0.1 M; and 0.3 M in 0.5 M KOH followed by GC and FTIR testing to identify derivative products resulting from glucose oxidation. CH4 and butyric acid were found as products of glucose oxidation in photoelectrochemical with the most optimal process being untreated conditions with 0.3 M glucose at a potential of 0.3 V.
