Metal-organic hybrid: Photoreduction of CO2 using graphitic carbon nitride supported heteroleptic iridium complex under visible light irradiation

Conjugated Electron Donor–Acceptor Hybrid Polymeric Carbon Nitride as a Photocatalyst for CO2 Reduction

“…The peak at 27.5° of the crystal structure face is a strong, broad and intense peak corresponding to the inter-planar stacking of aromatic systems [35,36]. All samples show these peaks and the aforementioned peak 27.5° peak due to disturbance of graphitic motifs resulting from the co-polymerization [37,38]. The peak displayed by all samples at 13.1° is a weak peak indexed to the (100) crystal plane which demonstrates the in-plane structural packing motif and the inter-planar stacking of aromatic systems [39,40].…”

Nanostructured Carbon Nitrides for CO2 Capture and Conversion

“…Metal–organic complexes such as Co(bpy 3 ) 3 Cl 2 and Ru II binuclear complexes can act as homogeneous electrochemical catalysts for CO 2 reduction. Several reports on the increased photocatalytic activity of the g‐C 3 N 4 for CO 2 photoreduction using such hybrid systems with metal–organic complexes exist in the literature . In these hybrid systems, metal–organic complexes play the role of a catalytic center, whereas the g‐C 3 N 4 works as a capture/photoactivation substrate of CO 2 .…”

Photochemical Oxidative Coupling of 2‐Naphthols using a Hybrid Reduced Graphene Oxide/Manganese Dioxide Nanocomposite under Visible‐Light Irradiation

“…Composites prepared by the combination of MnO 2 with other semiconductors, such as TiO 2 and ZnO, have a sufficient band gap to provide activity in the visible‐light region . Recently, our group established a concept to immobilize metal nanoparticles (NPs), complexes, salts, and oxides onto photoactive semiconductor supports either by an in situ or postgrafting approach to develop high‐performance photocatalysts with additional benefits of facile recovery and recycling for various transformations . Graphene oxide and reduced graphene oxide (rGO), which are fascinating carbon nanomaterials because of their extraordinary chemical, mechanical, and optical properties, have become used widely as semiconductors to immobilize various sensitizers, which include metal NPs and metal complexes, to develop improved photocatalysts that result from the synergistic combination of the individual properties of the component materials …”
