Deciphering Au-manganese oxide nanopetals plasmon–exciton co-driven artificial photosynthesis and Suzuki-Miyaura coupling reactions

CuO@Ag/NH2-MIL-88B(Fe) Heterojunction Photocatalyst for the Photothermal Codriven Synthesis of Benzimidazoles and Biaryls

“…It seems that the reaction requires light and heat; thus, this method can be considered a photothermal synthetic protocol. The photogenerated heat and the formation of hot e – as a result of the LSPR of Ag NPs enhance the efficiency of the photoinduced synthesis of biaryls . Finally, the optimal conditions in entry 6 were chosen for the synthesis of biaryl derivatives.…”

“…48 Since the pristine MOF was not individually able to proceed the coupling reaction, CuO@ Ag NPs were the main component for this photothermal reaction, and the MOF acted as a cocatalyst to facilitate the charge separation. The photogenerated hot e − from Ag NPs, 49 by LSPR, can be transferred to CuO and new e − can be generated, which might be used (besides h + ) for the activation of adsorbed intermediates. The scavenger test, utilizing AgNO 3 , EDTA, and isopropyl alcohol, was conducted for the model reaction.…”

“…Since surface plasmon resonance can stimulate the photocatalytic activity, Pd-based catalysts have been modified by alloying with gold (e.g., HUY@S-TOH@AuPd) to generate bimetallic systems. However, the use of noble metal species (e.g., Pd) has raised some economic concerns for industrialization; therefore, other bimetallic systems (Pd-free), for instance, CoPc/NiO, Au/MnO nanopetals, and RuCo NPs@[KIT-6]-PEG/imide have been introduced. Recently, a zirconium-based MOF was utilized for supporting bimetallic NPs for the Suzuki–Miyaura reactions such as Au/Pd@UiO-66-NH 2 and CuPd@NH 2 -UiO-66 …”

Synergistic Trimetallic Nanocomposites as Visible–NIR–Sunlight-Driven Photocatalysts for Efficient Artificial Photosynthesis

“…Recently, manganese oxide (MnO 2 ) attracted much attention as a promising semiconductor material and a new-generation photothermoelectric responsive catalyst for several environment-cleaning catalytic processes. − However, the narrow band gap of MnO 2 led to a low photocatalytic activity under visible light, and hence, further improvement in the photocatalytic activity of MnO 2 by combining with other semiconductor materials could be an attractive solution. − The synergetic effect between transitional metal oxides could be highly effective and often favors the improvement of catalytic activity. , In addition, MnO 2 suffers from poor electron transport and fast light-induced electron–hole recombination which limited its photocatalytic activity. − …”
