Insights into synergistic effect of Pd single atoms and sub-nanoclusters on TiO2 for enhanced photocatalytic H2 evolution

Anchored Cu single atoms on porous g-C3N4 for superior photocatalytic H2 evolution from water splitting

“…Recently, single-atom catalysts (SACs) for photocatalytic H 2 evolution have drawn tremendous attention for the maximum utilization of atoms and high efficiency of photo-generated charge separation. 20,21 Xiang et al 22 reported that Cu single atoms (CuSA) were loaded on crystalline CN nanorod by molten salts and the reux method, and the photocatalytic activity of the CuSA loaded sample enhanced nearly 2 times. However, it was difficult to anchor large amounts of single atoms due to the low specic surface area of CN.…”

Research progress of MIL-125 and its modifications in photocatalytic hydrogen evolution

“…7(e)). Moreover, Lv et al 108 further studied the coordination between the Pd sub-nanoclusters and the Pd single atoms on the substrate of TiO 2 and found that the Pd sub-nanoclusters can effectively promote the electron transfer of the Pd single atoms. It further improved the hydrogen evolution activity and the photocatalyst had excellent stability.…”

Synergy Between Supported Metal Single Atoms and Nanoparticles and their Relevance in Catalysis

“…The same reaction was studied on Pd SA + NP /TiO 2 catalysts. [57] Theoretical calculations have shown that the synergistic effect of Pd NP and Pd SA can optimize the d-band center, and equilibrate the adsorption and desorption of intermediates during the reaction. The Pd NP effectively promote the electron transfer to Pd SA resulting in superior charge carrier separation efficiency.…”

“…The Au NP and Au SA possess different affinities for electrons, inducing their different roles as electron donors and reservoirs during charge separation, respectively. The same reaction was studied on Pd SA+NP /TiO 2 catalysts [57] . Theoretical calculations have shown that the synergistic effect of Pd NP and Pd SA can optimize the d ‐band center, and equilibrate the adsorption and desorption of intermediates during the reaction.…”
