“…From the perspective of semiconductor photocatalysis, the premise of high photocatalytic efficiency is the efficient separation and rapid transfer of photogenerated e - / h + pairs, thereby prolonging their lifetimes and inhibiting their recombination.

“…It is worth nothing that the high specific surface area as well as porous structure of MOFs benefits for CO 2 adsorption, while the alternative ligands endow MOFs with adjustable band structure and spectra response range, thus providing a series of promising candidates for the design and construction of direct Z-scheme systems for efficient photocatalytic CO 2 reduction. With deepening of the research on the Z-scheme photocatalytic system and the recognition of its photocatalytic performance, more and more different types of Z-scheme photocatalysts have been developed ( Raza et al, 2020 ; Zeng et al, 2020 ), accelerating the process of photocatalytic CO 2 reduction from basic research to practical application.…”

Photocatalytic conversion of CO2 into solar fuels has gained increasing attention due to its great potential for alleviating the energy and environmental crisis at the same time. The low-cost TiO2 with suitable band structure and high resistibility to light corrosion has proven to be very promising for photoreduction of CO2 using water as the source of electrons and protons. However, the narrow spectral response range (ultraviolet region only) as well as the rapid recombination of photo-induced electron-hole pairs within pristine TiO2 results in the low utilization of solar energy and limited photocatalytic efficiency. Besides, its low selectivity toward photoreduction products of CO2 should also be improved. Combination of TiO2 with other photoelectric active materials, such as metal oxide/sulfide semiconductors, metal nanoparticles and carbon-based nanostructures, for the construction of well-defined heterostructures can enhance the quantum efficiency significantly by promoting visible light adsorption, facilitating charge transfer and suppressing the recombination of charge carriers, resulting in the enhanced photocatalytic performance of the composite photocatalytic system. In addition, the adsorption and activation of CO2 on these heterojunctions are also promoted, therefore enhancing the turnover frequency (TOF) of CO2 molecules, so as to the improved selectivity of photoreduction products. This review focus on the recent advances of photocatalytic CO2 reduction via TiO2-based heterojunctions with water oxidation. The rational design, fabrication, photocatalytic performance and CO2 photoreduction mechanisms of typical TiO2-based heterojunctions, including semiconductor-semiconductor (S-S), semiconductor-metal (S-M), semiconductor-carbon group (S-C) and multicomponent heterojunction are reviewed and discussed. Moreover, the TiO2-based phase heterojunction and facet heterojunction are also summarized and analyzed. In the end, the current challenges and future prospects of the TiO2-based heterostructures for photoreduction of CO2 with high efficiency, even for practical application are discussed.

“…When the said ceramic protecting the plasmonic core from the environment also has semiconducting properties, a metal-semiconductor heterojunction is created. The built-in electric field associated with such a metal-semiconductor heterojunction is a highly effective method to separate oppositely charged carriers and enhance the charge transfer efficiency of a plasmonic hybrid nanoparticle [ 11 , 12 ]. Semiconductor shells typically have a high frequency dielectric constant higher than 5, which is complementary to the negative relative permittivity exhibited by the coinage metals over the visible and near-infrared spectra range.…”

The substitution of time- and labor-intensive empirical research as well as slow finite difference time domain (FDTD) simulations with revolutionary techniques such as artificial neural network (ANN)-based predictive modeling is the next trend in the field of nanophotonics. In this work, we demonstrated that neural networks with proper architectures can rapidly predict the far-field optical response of core–shell plasmonic metastructures. The results obtained with artificial neural networks are comparable with FDTD simulations in accuracy but the speed of obtaining them is between 100–1000 times faster than FDTD simulations. Further, we have proven that ANNs does not have problems associated with FDTD simulations such as dependency of the speed of convergence on the size of the structure. The other trend in photonics is the inverse design problem, where the far-field optical response of a spherical core–shell metastructure can be linked to the design parameters such as type of the material(s), core radius, and shell thickness using a neural network. The findings of this paper provide evidence that machine learning (ML) techniques such as artificial neural networks can potentially replace time-consuming finite domain methods in the future.

“…There are many ways to reduce GHG emission (capture and store, to use alternative energy sources, to use new production technologies), however, to significantly reduce GHG impact on the environment the conversion technologies of it (especially CO 2 gas) should be developed and used worldwide [3]. The conversion technologies require a large amount of very expensive catalysts because precious metals (Pt, Pd, Au) are used as active components [4][5][6]. Besides, the application of traditional catalysts is limited by their thermal resistance, little reserves, due to difficulties in recovery, secondary pollution, etc.…”

This work aims to investigate the influence of Cr 3+ , Co 2+ and Cu 2+ on the formation of calcium silicates hydrates in CaO-SiO 2-Al 2 O 3-H 2 O system under hydrothermal conditions. The dry primary mixture with the molar ratio CaO/(SiO 2 + Al 2 O 3) = 1.5 and Al 2 O 3 /(Al 2 O 3 + SiO 2) = 0.05 was mixed with heavy metal nitrate solutions (metal ions concentration-10 g/l) to reach the water/solid ratio of the suspension equal to 10.0. The hydrothermal synthesis was carried out in unstirred suspensions, under saturated steam pressure at 200°C temperature for 0-72 hours. It was determined that nature of metal ions have influence on both mineral composition and thermal stability of synthesis products. It was obtained that by increasing synthesis temperature up to 200°C, all Cr 3+ and Co 2+ ions were intercalated into the structure of synthesis products. Meanwhile Cu 2+ ions participate in chemical reactions and as a result copper oxide were formed. The products of synthesis were characterized by STA, DSC, XRD and AAS analyses.
