Semi-biological approaches to solar-to-chemical conversion

“…233 In light of its cytotoxicity, CdS has been substituted with organic semiconductors, i.e., perylene diimide derivative (PDI) and poly(fluorene-co-phenylene) (PFP) as the photosensitiser. 234 PDI and PFP could be immobilised on the surface of M. thermoacetica through electrostatic and hydrophobic interactions, which enabled efficient electron transport across the cellular membrane. Such microbial hybrid system registered a quantum efficiency of 1.6%.…”

Synthetic Organic Design for Solar Fuel Systems

“…[56] More robust and red-light absorbing PSs [57] are also in demand as well as ab etter understanding of aqueous media-organic system interfaces and the development of oxidative chemistry. [58] Finally,t he integration of organic materials with biological systems, [59] and the prospect of their high throughput analysis by robotics [60] represent further exciting avenues of future research. We therefore envision many possibilities to employ organic chemistry in the future development of electro-and photocatalytic systems.…”

Material–Microbe Interfaces for Solar-Driven CO2 Bioelectrosynthesis

“…In the same year, a living quantum dot (QD) bacterial hybrid was constructed through the self-assembly of biocompatible QD and specific enzymes inside the living cells [62]. See [30][31][32]41,[52][53][54][55][56]63,68,70]. efficiency in CO 2 photoreduction is to combine inorganic and biological systems as hybrid systems.…”

“…Using organic semiconductor, a biohybrid system has been synthesized by Gai and coworkers for CO 2 reduction to acetic acid [70]. M. thermoacetica was coated with n-type perylene diimide derivative (PDI) and p-type poly(fluorene-co-phenylene) (PFP) semiconducting material for photosensitization.…”

“…However, the inorganic NPs may pose environmental hazards when applied in industrial scale. Further, the optical properties of inorganic NPs are difficult to control [27,70]. To the contrary, the organic semiconductors such as g-C 3 N 4 , eosin Y, PFP/PDI heterojunction, and photosensitizer protein show comparable photosensitization ability with that of inorganic semiconductors and are convenient for large-scale application.…”
