Porous-CdS/Cu2O/graphitic-C3N4 dual p-n junctions as highly efficient photo/catalysts for degrading ciprofloxacin and generating hydrogen using solar energy

Improved Interfacial Charge Transfer on Noble Metal‐Free Biomimetic CdS‐Based Tertiary Heterostructure @ 2D MoS2‐CdS‐Cu2O with Enhanced Photocatalytic Water Splitting

“…Possibly water splitting efficiency of the present catalyst is better than the earlier reported efficiency on any noble metal free tertiary catalyst system. [ 44–47,49 ]…”

“…[ 39–41 ] On the other hand, Cu 2 O decorated MoS 2 showed seven‐fold hydrogen production efficiency with improved photostability of Cu 2 O [ 42,43 ] which is explained based on p‐n junction formation in the interface. To further improve the hydrogen efficiency, noble metal‐free tertiary heterojunctions involving dual p‐n junction, [ 44,45 ] dual Z‐scheme, [ 46 ] heterojunction, [ 47 ] and bifunctional [ 48 ] catalysts were explored in recent times. Similarly, ternary Fe 2 O 3 /MoS 2 /Cu 2 O having a Z‐scheme system showed improved photocurrent for environmental purification and water oxidation.…”

Pharmaceuticals and personal care products in water and wastewater: a review of treatment processes and use of photocatalyst immobilized on functionalized carbon in AOP degradation

“…Fabrication of g-C 3 N 4 based semiconductor photocatalyst is considered as one of the effective and more feasible strategies to enhance the photocatalytic activity of g-C 3 N 4 where the formation of a heterojunction system improve the photo-generated electron-hole pairs separation leading to the improvement in their photocatalytic activity as seen in the following g-C 3 N 4 based photocatalyst g-C 3 N 4 /TiO 2 , g-C 3 N 4 /WO 3 , g-C 3 N 4 /CdS, g-C 3 N 4 /Cu 2 O, g-C 3 N 4 /CdS/Cu 2 O for the degradation of numerous organic pollutants in the environment [239][240][241]. Chen et al [242] synthesized a series of visiblelight-driven MgIn 2 S 4 /g-C 3 N 4 heterostructures for the degradation of 4-nitroaniline and methyl orange.…”

Near-infrared light-triggered nano-prodrug for cancer gas therapy

“…However, the low solubility of H 2 in water makes it spread easily in the blood and prevents enrichment in the tumor site [ 209 ]. It is well known that the water content of the human body ais approximately 70%, which provides us with a way of thinking about how to introduce photocatalytic nanomaterials into tumors and suggests that catalyzing water to produce H 2 will be a promising strategy to enhance H 2 accumulation in tumors [ 216 ]. In recent years, Z-scheme heterojunction systems have been widely used in the generation of PDT and H 2 because they can separate electron–hole pairs and improve redox potential [ 217 ].…”
