Photocatalysis reduces the challenges associated with power activities by the conversion of solar energy into chemical energy. Herein, sulfur‐doped graphitic carbon nitride nanoplate (S‐g‐CN‐NP) via polycondensation and vapor oxidative treatment methods as a promising solar light‐reactive photocatalyst has been designed. The photo‐mediated reduction of NAD+ is used to facilitate the extremely efficient solar light‐driven photocatalytic selective production of nicotinamide adenine dinucleotide (NADH). The S‐g‐CN‐NP photocatalyst shown excellent optical and photoelectrical properties, supporting an NADH yield of (97±0.010 %), which was 1.5 folds higher than that of S‐g‐CN powder (65±0.012 %). Through the transformation of S‐g‐CN powder to nanoplates, the improvement of photocatalytic in S‐g‐CN‐NP was primarily ascribed to the growth of active sites of the nanoplates. The current study focuses on the creation and use of an S‐g‐CN‐NP photocatalyst for direct selective NADH regeneration under solar light.

“…NAD(P)H is a cofactor in enzymatic reduction and the regeneration of NAD(P)H is essential for the practical application of reductive enzymes. [25][26][27][28][29][30][31][32][33][34] According to previous reports, HPB could be excited by visible light to form HPB* with reductive potential more negative than [Cp*Rh(bpy)H 2 O] 2þ , thus, it is possible for nTp-TTA/POM-x to drive the photocatalytic NAD þ reduction with cascade electron relay on the basis of energy diagram ( Figure 3A). [14] The photocatalytic NADH regeneration was used as a model reaction to test the catalytic performance of nTp-TTA/POM-x with [Cp*Rh(bpy)H 2 O] 2þ as electron mediator and TEOA as hole sacrificial reagent using Xe lamp (λ ≥ 420 nm) ( Table 1).…”

Covalent organic frameworks (COFs) are novel crystalline polymers with a unique designable feature at molecular level via weaving chemistry. [1,2] 2D COFs with a variety of ordered π systems provide a desirable platform for developing visible-light responsive photocatalysts for solar energy storage and conversion and have already shown potential applications in photocatalytic water splitting, CO 2 reduction, and organic synthesis. [3-11] In regardless of suitable bandgap and band structure, COFs in most cases afforded very low quantum efficiency in photocatalysis. Considering that the separation and transportation of the photogenerated charges is the key step in photosynthesis, the fast extraction of photogenerated electrons confined in π orbitals of COFs is very important for efficient photosynthesis. In natural photosynthesis, the photogenerated holes and electrons are spacially separated in PS II (catalyze H 2 O oxidation to H þ and O 2) and PS I (photoenzymatic reduction of NAD(P) þ to NAD(P)H). [12] The excited electrons are transferred from PS II to PS I through multistep with the assistance of mediators to inhibit the charge recombination. Inspired by natural photosynthesis, the utilization of an electron mediator is an efficient strategy to enhance the charge separation of COFs for efficient artificial photosynthesis. A good electron mediator should possess redox potentials alignment with the band structure of COFs and the properties of easy electron acception and donation. Polyoxometallates (POMs) could be reduced to heteropolyblue (HPB) via accepting electrons. [13] More interestingly, HPB can be excited by visible and near-infrared light at about 700 nm via intervalence charge transfer to regain the energy that is lost in the reduction process and the excited HPB* facilely denotes electrons to electron acceptors, e.g., H þ , O 2 , and metal complexes to drive the photocatalytic reductive reactions. Previous studies showed that the photocatalytic activity of semiconductors, e.g., C 3 N 4 , TiO 2 were greatly promoted by coupling with POM in photocatalytic CO 2 reduction, water oxidation, and organic pollutants removal due to the enhanced charge separation. [14-17] Though POM is a good candidate as electron mediator and electron storage tank, the coupling of COFs and POM has not been reported yet for artificial photosynthesis as far as we know, possibly related with the difficulty in hybridizing of the POM and COFs. Herein, we report the fabrication of nanoCOF/POM composites for the first time by simply mixing the cetyltrimethylammonium bromide/sodium dodecyl sulfate (CTAB/SDS, molar ratio of 97/3) micelle stabilized nanoCOF colloid solution with Na 3 PW 12 O 40 (Scheme 1). NanoCOF/POM composites possess visible-light responsive properties inherited from nanoTp-TTA COF (synthesized using 1,3,5-triformylphloroglucinol and 4,4 0 ,4 00-(1,3,5-triazine-2,4,6-triyl)trianiline as precursors).

“…Due to the metal-free composition, low-cost, suitable bandgap and beneficial energy levels, graphitic carbon nitride (g-C 3 N 4 ) has recently attracted much attention as photocatalyst for water splitting, CO 2 reduction, pollutant degradation, organic syntheses, and bacterial disinfection under visible light irradiation in the past decade Cao et al, 2015;Liu et al, 2015;Liu et al, 2016b;Zhang et al, 2017;Jia et al, 2019;Zhang et al, 2019;Giusto et al, 2020b;Lim et al, 2020;Zhang et al, 2020a;Zhang et al, 2020b). Especially, for bacterial disinfection, most of the previously reported studies focused mainly on the bulk particulate material (Shen et al, 2017;Ran et al, 2019;Gan et al, 2020;Ni et al, 2020;Zhao et al, 2021), which makes recycling difficult and would inevitably lead to secondary pollution of fine nanoparticles (Wang et al, 2019a).…”

Graphitic carbon nitride (g-C3N4) as metal-free visible light photocatalyst has recently emerged as a promising candidate for water disinfection. Herein, a nanowire-rich superhydrophilic g-C3N4 film was prepared by a vapor-assisted confined deposition method. With a disinfection efficiency of over 99.99% in 4 h under visible light irradiation, this nanowire-rich g-C3N4 film was found to perform better than conventional g-C3N4 film. Control experiments showed that the disinfection performance of the g-C3N4 film reduced significantly after hydrophobic treatment. The potential disinfection mechanism was investigated through scavenger-quenching experiments, which indicate that H2O2 was the main active specie and played an important role in bacteria inactivation. Due to the metal-free composition and excellent performance, photocatalytic disinfection by nanowire-rich g-C3N4 film would be a promising and cost-effective way for safe drinking water production.
