Kemampuan katalis zeolit dapat ditimgkatkan melalui modifikasi zeolit dengan pengembanan logam. Pada penelitian ini telah dilakukan modifikasi zeolit alam melalui pengembanan besi (Fe) dan kobalt (Co) untuk katalis oksidasi fenol. Modifikasi zeolit alam dilakukan melalui tahap pencucian asam menggunakan HF, HCl, dan NH 4 Cl dilanjutkan pengembanan logam. Karakterisasi produk dilakukan menggunakan x-ray diffraktometer, surface area analyzer, dan uji katalitik dilakukan terhadap sampel fenol. Hasil karakterisasi menunjukkan komposisi mineral komponen utama penyusun zeolit adalah mordenit, keasaman total katalis Fe 2 O 3 -zeolit yang diperoleh sebesar 2,7 mmol/g dan katalis CoO-zeolit sebesar 2,5 mmol/g, katalis Fe 2 O 3 -zeolit dan katalis CoO-zeolit memiliki luas permukaan spesifik dan volume pori total secara berurutan, yaitu 38,3918 m 2 /g, 16,6569 cm 3 /g dan 28,6209 m 2 /g, 12,5072 cm 3 /g serta katalis mampu meningkatkan kemampuan hidrogen peroksida (H 2 O 2 ) dalam mendegradasi fenol sebesar 16,93% pada dosis katalis 5 mg, konsentrasi awal fenol 100 mg/L, volume fenol 20 mL, dan waktu kontak 24 jam.}, issn = {2597-9914}, pages = {1--5} doi = {10.14710/jksa.16.1.1-5}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/17909} }
