note: Hidrogen salah satu energi alternatif pengganti bahan bakar fosil yang dapat menimbulkan emisi gas rumah kaca. Proses produksi hidrogen yang masih mengandalkan energi tak terbarukan memerlukan metode aletrnatif lainnya yang ramah lingkungan. Selain itu, permasalahan pencemaran lingkungan perairan sangat menjadi perhatian masyarakat luas. Salah satu pencemaran lingkungan perairan diakibatkan zat warna methylene blue yang memiliki struktur sulit diuraikan. Adapun metode untuk memproduksi hidrogen sekaligus dapat menguraikan limbah methylene blue yaitu dengan menggunakan elektrokoagulasi, fotokatalisis, dan kombinasi keduanya. Fotokatalis yang digunakan pada metode ini yaitu TiO2 Nanotube Array dengan sensitizer graphitic carbon nitride (TNTAs/g-C3N4), dimana g-C3N4 tersintesis dari urea dan tiourea. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan metode elektrokogulasi, fotokatalisis, maupun kombinasi pada proses produksi hidrogen serta degradasi limbah methylene blue. Fotokatalis TNTAs dilakukan sintesis dengan menggunakan metode anodisasi, kemudian dilapisi dengan sensitizer g-C3N4 sehingga menjadi fotokatalis TNTAs/g-C3N4 melalui proses impregnasi. Mengamati pengaruh penggunaan fotokatalis dan perbedaan metode pada produksi hidrogen dan degradasi limbah methylene blue. Melakukan karakterisasi menggunakan spektrofotometri Vis, SEM EDX, dan XRD. Hasil SEM menunjukkan morfologi TNTAs memiliki diameter 178 nm dan tebal 89 nm. Kinerja fotokatalis terbaik dihasilkan oleh TNTAs/g-C3N4 tersintesis tiourea dengan kemampuan produksi H2 sebesar 10,678 μmol dan kemampuan degradasi methylene blue mencapai 64%. Proses kombinasi elektrokoagulasi dan fotokatalisis dilakukan dengan menggunakan fotokatalis TNTAs/g-C3N4, anoda alumunium, dan katoda stainless steel 316 pada tegangan 50 V selama 3 jam menunjukkan kondisi optimum proses produksi H2 hingga 1554,830 μmol dan persentase total degradasi methylene blue sebesar 82%.
abstract: Hydrogen is one of the alternative energy sources to replace fossil fuels that can cause greenhouse gas emissions. The hydrogen production process that still relies on non-renewable energy requires other alternative methods that are environmentally friendly. In addition, the problem of water pollution is a major concern for the wider community. One of the water pollution is caused by the dye methylene blue which has a structure that is difficult to decompose. The method for producing hydrogen while also being able to decompose methylene blue waste is by using electrocoagulation, photocatalysis, and a combination of both. The photocatalyst used in this method is TiO2 Nanotube Array with graphitic carbon nitride (TNTAs/g-C3N4) sensitizer, where g-C3N4 is synthesized from urea and thiourea. This study aims to determine the effect of using electrocoagulation, photocatalysis, or a combination of methods on the hydrogen production process and the degradation of methylene blue waste. TNTAs photocatalysts are synthesized using the anodization method, then coated with g-C3N4 sensitizer to become TNTAs/g-C3N4 photocatalysts through the impregnation process. Observing the effect of photocatalyst use and different methods on hydrogen production and degradation of methylene blue waste. Characterization using Vis spectrophotometry, SEM EDX, and XRD. SEM results show that the morphology of TNTAs has a diameter of 178 nm and a thickness of 89 nm. The best photocatalyst performance is produced by thiourea-synthesized TNTAs/g-C3N4 with an H2 production capacity of 10.678 μmol and a methylene blue degradation capacity of 64%. The combination process of electrocoagulation and photocatalysis was carried out using TNTAs/g-C3N4 photocatalyst, aluminum anode, and 316 stainless steel cathode at a voltage of 50 V for 3 hours showing optimum conditions for the H2 production process of up to 1554.830 μmol and a total percentage of methylene blue degradation of 82%.
