Abstract

Bahan bakar fosil sudah cukup lama diandalkan dalam kebutuhan manusia sehari-hari, akibatnya penyimpangan iklim mengancam lingkungan secara global. Energi terbarukan yang menjanjikan serta ramah lingkungan dibutuhkan yaitu Hidrogen. Oleh karena itu, Teknologi photoelectrochemical (PEC) dengan semikonduktor yang mampu menangkap sinar matahari untuk memproduksi hidrogen diperlukan. Perovskite CsPbBr3 hadir sebagai bahan semikonduktor yang mudah difrabikasi dan mempunyai stabilitas yang baik. Penelitian ini bertujuan untuk menganalisis pengaruh heat treatment fotoanoda CsPbBr3 terhadap produksi arus dan hidrogen fotoanoda CsPbBr3 melalui oksidasi glukosa. Prosedur untuk melakukan penelitian ini dimulai dengan pembuatan larutan CsPbBr3 dengan metode Ligan Assisted Reprecipitation (LARP) kemudian dilanjutkan dengan proses fabrikasi fotoanoda FTO/TiO2/CsPbBr3 dan dilakukan heat treatment 90oC serta 110oC. Fotoanoda CsPbBr3 yang telah dilakukan heat treatment dan tanpa perlakuan sebagai variasi perbandingan diuji XRD dan SEM. Hasil tersebut menunjukkan fotoanoda FTO/TiO2/CsPbBr3 tanpa perlakuan, partikel masih berbentuk spherical atau butiran lalu dilakukan heat treatment hingga temperatur 90oC bentuk cube dan rods sedang bertumbuh. Heat treatment hingga temperatur 110oC terlihat bahwa cube dan rods mendominasi bentuk partikel. Setelah itu, fotoanoda CsPbBr3 dilakukan pengujian CV, LSV dan GC dengan larutan konsentrasi glukosa 0,1 M, 0,2 M, dan 0,3 M serta larutan elektrolit 0,5 M KOH dibawah penyinaran dan tanpa penyinaran. Produksi arus memiliki performa yang baik pada fotoanoda FTO/TiO2/CsPbBr3 dengan perlakuan panas hingga 110oC kondisi dalam penyinaran. Hasil pengujian CV mendapatkan current density tertinggi yaitu 24,35 mA/cm2 dan potensial 0,310 V pada larutan glukosa dengan konsentrasi 0,2 M. Produksi hidrogen didapat 6,46 ml dengan pengujian GC dan hasil pengujian LSV didapatkan nilai onset potential -0,822 V dan current density yaitu -1,497 mA/cm2.

Fossil fuels have been relied on for quite a long time for human daily needs, as a result climate deviations threaten the environment globally. Renewable energy that is promising and environmentally friendly is needed, namely Hydrogen. Therefore, photoelectrochemical technology (PEC) with semiconductors capable of capturing sunlight to produce the required hydrogen. Perovskite CsPbBr3 is present as a semiconductor material that is easy to fabricate and has good stability. This study aims to analyze the effect of heat treatment of CsPbBr3 photoanode on current and hydrogen production of CsPbBr3 photoanode by oxidizing glucose. The procedure for conducting this study began with the preparation of a CsPbBr3 solution using the Ligand Assisted Reprecipitation (LARP) method, then continued with the FTO/TiO2/CsPbBr3 photoanode fabrication process and heat treatment at 90oC and 110oC. The CsPbBr3 photoanode that had been heat treated and untreated as a comparison variation was tested by XRD and SEM. These results show that the FTO/TiO2/CsPbBr3 photoanode without treatment, the particles are still spherical and then at 90oC the shape of cubes and rods are growing. Heat treatment to a temperature of 110oC shows that cubes and rods dominate the particle shape. After that, the CsPbBr3 photoanode was tested for CV, LSV and GC with glucose concentration solutions of 0.1 M, 0.2 M, and 0.3 M and electrolyte solutions of 0.5 M KOH under irradiation and without irradiation. Current production has good performance on FTO/TiO2/CsPbBr3 photoanodes with heat treatment up to 110oC in irradiation. The CV results obtained the highest current density of 24.35 mA/cm2 and a potential of 0.310 V in a glucose solution with a concentration of 0.2 M. Hydrogen production was obtained by 6.46 ml with the GC test and the LSV test results obtained an initial potential value of -0.822 V and a current density of -1.497 mA/cm2.
