In this work, we have synthesized AgBr-modified cobalt ferrite (CF) and zinc ferrite (ZF) combined with N-doped graphene (NG) via a modified hydrothermal process. Exploiting visible light, the photocatalytic performance of as-fabricated photocatalysts were used for successful photocatalytic degradation of malachite green (MG) and methyl orange (MO). The photodegradation of MG after 100 min followed the trend AgBr/CF/NG (98%) > AgBr/ZF/NG (95%) > CF (45%) > ZF (43%) > AgBr (41%) > NG (21%). For the degradation of MO, the abolition efficiency after 100 min followed the trend AgBr/CF/NG (99%) > AgBr/ZF/NG (96%) > CF (41%) > AgBr (40%) > ZF (38%) > > NG (23%). The rate constants of 0.034 and 0.032 min⁻¹ were attained for MG degradation using AgBr/CF/NG (R², 0.99) and AgBr/ZF/NG (R²: 0.98) photocatalyst, respectively, whereas AgBr/ZF/NG (R²: 0.98) and AgBr/CF/NG (R²: 0.97) had respective rate constants of 0.029 and 0.026 min⁻¹ for MO photodegradation. The intermediate formation during the process of photodegradation was studied by HPLC and GC-MS analysis. The adsorption experiments demonstrated that maximum adsorption of MG was at pH 4, whereas the maximum MG adsorption was at pH 8. Owning to recycle experiments, AgBr/ZF/NG and AgBr/CF/NG revealed 85% and 83% degradation efficiency, respectively, after ten consecutive cycles.

在这项工作中，我们通过改进的水热法合成了AgBr改性的钴铁氧体（CF）和锌铁氧体（ZF）以及N掺杂的石墨烯（NG）。利用可见光，将制成的光催化剂的光催化性能成功地用于孔雀石绿（MG）和甲基橙（MO）的光催化降解。100分钟后MG的光降解遵循以下趋势：AgBr / CF / NG（98％）> AgBr / ZF / NG（95％）> CF（45％）> ZF（43％）> AgBr（41％）> NG（ 21％）。对于MO的降解，100分钟后的废除效率遵循趋势AgBr / CF / NG（99％）> AgBr / ZF / NG（96％）> CF（41％）> AgBr（40％）> ZF（38） ％）>> NG（23％）。的0.034和0.032分钟的速率常数^-1中获得使用的AgBr / CF / NG（R MG降解²，0。²：0.98）分别为光催化剂，而AgBr / ZF / NG（R ²：0.98）和AgBr / CF / NG（R ²：0.97）对于MO光降解分别具有0.029和0.026min ^-1的速率常数。通过HPLC和GC-MS分析研究了光降解过程中的中间体形成。吸附实验表明，MG的最大吸附值为pH 4，而MG的最大吸附值为pH8。通过循环实验，AgBr / ZF / NG和AgBr / CF / NG的降解效率分别为85％和83％。 ，连续十个周期后。
