Heterogeneous N-coordinated single-atom photocatalysts and electrocatalysts

Boosting exciton dissociation and charge separation in pyrene-based linear conjugated polymers for efficient photocatalytic hydrogen production

“…We also tested the AQY based on different usage of catalyst. 50 To determine the direct evidence for the efficient hydrogenevolution performance of PyFO, we measured the femtosecond time-resolved transient absorption (TA) spectroscopy. We used 340 nm pump laser to excite electrons from the VB to CB in COPs.…”

Tuning the photosensitization efficiency of atomically precise metal nanoclusters by super-efficient and exquisite interface modulation

“…Conventional metal nanocrystals (NYs) constitute an imperative sector of nanomaterials for multitudinous catalysis. [1][2][3][4][5][6][7][8][9] When the size of metal NYs is reduced to be atomically small (<2 nm) with a precise number of metal atoms and surface ligands, they are referred to as "metal nanoclusters (NCs)" having physicochemical properties distinct from those of metal NY counterparts, which are featured by a molecule-like discrete energy band structure. [10][11][12][13][14][15] The favorable highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) gap renders the metal NCs emerging light-harvesting photosensitizers for photoredox catalysis.…”

A novel S-scheme heterojunction constructed by Ti-based hydrotalcite decorating MOFs for boosting CO2-to-CO photoreduction and mechanism insights

“…Thus, achieving the directional transport of the charge carriers and spatial separation of the oxidation/reduction reactions might be a prospective strategy toward this dilemma. [26][27][28][29] In other words, it was necessary to construct heterojunctions.…”
