Abstract

Kelemahan dari sumber energi berbasis fosil mendorong pengembangan sumber energy baru dan terbarukan (EBT), salah satunya yaitu hidrogen. Produksi hidrogen melalui water splitting dengan sumber energi matahari dan tambahan Ti02 sebagai fotokatalis berpotensi untuk dikembangkan karena Namun, TiCb memiliki kelemahan berupa celah pita yang lebar sehingga membutuhkan energy yang kitosan melalui metode solvotermal sebagai bahan fotokatalis. Material fotokatalis yang sudah disintesis, dikarakterisasi dengan X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), UV-Diffuse Reflectance (UV-DRS) dan Fourier Transform Infrared (FTIR). Dilakukan pula uji aktivitas fotokatalitik untuk mengetahui produksi hidrogen dengan menggunakan sensor MQ8 yang terintegrasi dengan sistem mikrokontroler Arduino dan Personal Computer. Terdapat empat variasi yang digunakan yakni TiCb/NiSe/Kitosan, TiCb/NiSe+Kitosan, TiCb/NiSe/NC dan TiCb/NiSe+NC. Hasil karakterisasi UV-Vis DRS menunjukkan adanya penurunan celah pita dengan penambahan material karbon dan nitrogen. Nilai celah pita terendah diperoleh 2.9eV pada variasi TiCb/NiSe+NC. Hasil uji aktivitas fotokatalitik menunjukkan TiCb/NiSe+NC sebesar 79.24 ppm, di mana terjadi kenaikan produksi hidrogen lebih banyak 324.36% dibandingkan produksi hidrogen menggunakan fotokatalis TiCb

The weakness of fossil-based energy sources encourages the development of new and renewable energy sources (EBT), one of which is hydrogen. Hydrogen production through water splitting using solar energy and the addition of Ti02 as a photocatalyst has the potential to be developed because However, TiCb has a weakness in the form of a wide band gap so it requires energy that is chitosan through the solvothermal method as a photocatalyst material. The synthesized photocatalyst material was characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), UV-Diffuse Reflectance (UV-DRS) and Fourier Transform Infrared (FTIR). A photocatalytic activity test was also carried out to determine hydrogen production using the MQ8 sensor integrated with the Arduino microcontroller system and Personal Computer. There are four variations used, namely TiCb/NiSe/Chitosan, TiCb/NiSe+Chitosan, TiCb/NiSe/NC and TiCb/NiSe+NC. The results of the DRS UV-Vis characterization showed a decrease in the band gap with the addition of carbon and nitrogen materials. The lowest band gap value was obtained at 2.9eV for the TiCb/NiSe+NC variation. Photocatalytic activity test results showed TiCb/NiSe+NC of 79.24 ppm, where there was an increase in hydrogen production of 324.36% more than hydrogen production using TiCb photocatalyst
