Recent advances in silver-based heterogeneous catalysts for green chemistry processes

Hydrogenation of nitrophenols catalyzed by carbon black-supported nickel nanoparticles under mild conditions

“…Based on the experimental results and the literatures [3,9,21,24], it can be understood that the present reduction process involves the following crucial steps as shown in scheme 1: (1) In the reaction system, the π-π stacking interaction between aromatic nitrophenol molecules and the surface of CB plays an important role in promoting the aromatic entities gaining easier access to Ni NPs.…”

“…Several approaches for the reduction of nitrophenols to aminophenols have been reported so far, such as iron-acid reduction [1,2,15], electrolytic reduction [16], catalytic hydrogenation [17][18][19][20][21], etc.…”

New insights into how RGO influences the photocatalytic performance of BiOIO3/RGO nanocomposites under visible and UV irradiation

“…Photocatalysis has demonstrated great potential in energy and environmental issues, such as solar energy conversion, pollutants decomposition, and carbon dioxide reduction [6][7][8][9][10] Wang and coworkers applied the new material of BiOIO 3 for photocatalytic degradation of MO under UV light irradiation originating from the heterolayered structure and internal polar field [11]. Huang et al also demonstrated that BiOIO 3 possessed high photocatalytic activity for the degradation of MO [12].…”

A general method to diverse silver/mesoporous–metal–oxide nanocomposites with plasmon-enhanced photocatalytic activity

“…Moreover, the photogenerated charge carriers can be efficiently separated at the interface between Ag and semiconductor, which allows the efficient formation of reactive oxygen species for the degradation of organic compounds [24,25]. Therefore, coupling metal oxide semiconductors with silver nanoporticles presents a promising strategy for designing advanced photocatalysts and elicits widespread research interest [26,27]. Awazu et al deposited TiO 2 film on nanoparticles comprising an Ag core covered with a silica (SiO 2 ) shell to prevent oxidation of Ag by direct contact with TiO 2 [28].…”
