Biohybrid Molecule‐Based Photocatalysts for Water Splitting Hydrogen Evolution

“…Sun et al synthesized a series of bacteriochlorophyll-a (BChl-a) based photocatalysts connected with different carotenoids. [85] The best photocatalytic performance for hydrogen revolution reached 15.5 μmol g À 1 h À 1 , which is much higher than BChl-a itself without connecting with the carotenoid moieties. It is inferred from the EIS test as well as the photocurrent test that the efficient charge transfer and relatively slow electron-hole pairs recombination process at the interface between dyad molecules and MXene.…”

Exploring the catalytic activity of Nb4C3Tx MXene towards the degradation of nitro compounds and organic dyes by in situ decoration of palladium nanoparticles

“…), X is carbon and/or nitrogen, and T x are surface terminations (-OH, -O-, and/or -F). 21 They have been applied to a wide array of fields like catalysis, 22 energy, 23,24 biosensors, [25][26][27] and water treatment applications. [28][29][30] The diverse applications of this material are due to its interesting properties like adsorption capacity, large surface area, high electrical conductivity, and good biocompatibility.…”

Electronic absorption spectral analysis of chlorin-based dyad sensitizers by TD-DFT calculations

“…Although the sophisticated systems found in nature are fascinating, the examples of photovoltaic devices focusing on the usage of natural chlorophylls (Chls) and bacteriochlorophylls (BChls) have been quite limited compared to other organic functional dyes such as artificial porphyrins or phthalocyanines. Our group has been successfully developed semi-synthetic Chl derivatives toward solar energy applications [7], and besides, recent studies demonstrated the utilization of Chl-based dyes as photocatalysts for water splitting hydrogen evolution [8][9][10][11][12][13] or key components for energy storage devices [14,15] as well as BChlbased sensitizers for OSC [16] and Chl-sensitized TiO 2 electron transport layer for PSC [17]. To reveal the working mechanism of Chl-based BSCs, physical techniques such as sub-picosecond transient absorption spectroscopy and pumpprobe time-resolved absorption spectroscopy were employed [18,19], and an unconventional energy alignment of OSC that disobeyed the classical theory was clarified using a bilayer heterojunction model [20].…”
