An antimonene/Cp*Rh(phen)Cl/black phosphorus hybrid nanosheet-based Z-scheme artificial photosynthesis for enhanced photo/bio-catalytic CO₂ reduction

Abstract

A biomimicking Z-scheme photocatalytic system was constructed using dual-functionalized polymer covalent cross-linking electron mediator to catenate antimonene and black phosphorus nanosheets.

A Review on the Design and Performance of Enzyme-Aided Catalysis of Carbon Dioxide in Membrane, Electrochemical Cell and Photocatalytic Reactors

“…It is reported that the large overpotential and the low current density and stability have made it difficult to satisfy commercial demands [20]. The biocatalyzed artificial photosynthesis system is also still being studied, as the majority of the existing semiconductors or organic photocatalysts have low light absorption ability and reduction/oxidation potentials [21]. In this paper, the multi-enzymatic cascade conversion of CO 2 in EMRs, electrochemical cells and photocatalytic reactor systems will be reviewed and the performance of each enzyme reactor system will be compared by observing the biocatalytic productivity attained by each system.…”

“…The large surface area hold by the 2D-layered material could provide more surface active sites and superior electron mobility for the photocatalytic reaction. Recently, Ji et al successfully utilized a Z-scheme-based photocatalytic system to catalyze the biocatalytic reduction of CO 2 to CHOOH [21]. With the utilization of hybrid black phosphorus (BP) and antimonene (AM) ultrathin nanosheets and the application of the Z-scheme electron transfer mechanism, the photocatalytic system is able to improve the separation efficiency of the electron-hole pairs, resulting in high redox potentials for the photochemical regeneration of NADH.…”

“…Aresta et al [74] modified the structure of the TiO 2 photocatalyst with a photosentisizer so that more light could be absorbed by the photocatalyst to obtain a high NADH regeneration yield. Ji et al [21] developed a Z-scheme photocatalytic system to improve electron transfer efficiency and promote redox potentials, but the biocatalytic productivity of the photocatalytic system was still unable to achieve levels above 90%. Furthermore, the photochemical regeneration of NADH without an electron mediator could also lead to the synthesis of inactive NADH compounds, such as 1,6-NADH, instead of active 1,4-NADH.…”

p-n Heterojunction-based Thermoelectric Generator for Highly Efficient Cancer Thermoelectric Therapy

“…43,44 Obviously, the thermoelectric e ciency not only relates to physicochemical properties of TE materials, such as Seebeck coe cient, electrical conductivity, and thermal conductivity, but it also has a linear correlation with the operating temperature, in which higher temperature endows more effective electron-hole pairs separation and higher thermoelectric e ciency, which is also the main obstacle for applications in biomedical elds of TE materials. 45 Based on our previous studies, [46][47][48][49][50] heterojunction construction, including p-n junction and Z scheme junction, has been demonstrated as an e cient strategy for improving electron-hole pairs separation and enhancing the catalytic e ciency. After contacting of p-type and n-type semiconductors, the interfacial electric eld will be constructed, in which the separated electrons and holes in both semiconductors would transfer in the opposite direction and locate in different semiconductors.…”
