A series of environmentally benign and highly efficient Z-scheme Ni-doped CuWO4 nanoparticles on graphitic carbon nitride (g-C3N4) were synthesized.

A series of WO3@g-C3N4 nanocomposites were prepared by following a facile, cost-effective chemical rote and characterized by different techniques. They are promising photocatalyst with high potential for solar light harvesting and environmental remediation.

Quantum chemical calculations have been carried out to understand the ligand properties of skeletally modified cyclic alkyl amino carbenes. The stability of these carbenes has been assessed from an evaluation of their singlet-triplet and stabilization energy values. Ylide substituted carbenes are found to be more stable than non-ylidic ones in their optimized singlet state. Nucleophilicity and electrophilicity indices values were evaluated in order to further investigate the reactivity of these carbenes. The calculated values of proton affinities and the degree of gallium pyramidalization in the carbene-GaCl adducts correlate well with the σ-basicity of these carbenes. The reactivity of non-ylidic carbenes toward the activation of both H and NH are calculated to be more favourable compared to that of parent CAAC. On the other hand, ylide anchored carbenes are found to be unsuccessful toward the activation of both H and NH .
