Nanomaterials photocatalytic activities for waste water treatment: a review

Enhanced photocatalytic degradation of levofloxacin over heterostructured C3N4/Nb2O5 system under visible light

“…This significant improvement in activity was likely due to the synergy of the construction of heterojunction and interface formation, unique Lewis basic sites of carbon nitride surface, and intrinsic Lewis acid sites in Nb 2 O 5 , thus enhancing surface reactivity [ 55 ]. The quantitative assessment of levofloxacin photodecomposition on the photocatalyst surface was calculated using relation where k is rate constant (min −1 ), C 0 is the initial concentration of dye and c is the actual concentration of target dye at irradiation time t and results are summarized in Table 1 [ 56 ]. The apparent rate constant 0.01558 min-1 shown in Fig.…”

Nanoscience and nanotechnology for water remediation: an earnest hope toward sustainability

“…[82][83][84] Typically, catalytic degradation processes involve the following stages: adsorption of the pollutant molecules, absorption of the irradiated light, and eventually charge transport and separation and degradation of pollutants. 85 From a fundamental perspective, the reason behind the superior photocatalytic efficiency of nano-catalyst materials can be attributed to two main nano-properties.…”

Synergistic Multisystem Photocatalytic Degradation of Anionic and Cationic Dyes Using Graphitic Phase Carbon Nitride

“…Dyes are widely used in various industries such as textiles, leather, and paper, and it has been reported that about 30% of synthetic dyes are discharged into the environment [ 8 , 9 , 10 ]. Dye wastewater is complex and difficult to degrade, contains chromogenic and polar groups, and can cause eutrophication of water bodies [ 11 , 12 , 13 ]. Dyes can induce allergies and cancer, damage the respiratory system, nervous system and skin, and cause harm to the human body.…”
