Summary: The coupling of ferroelectric and photoexcitation can effectively enhance the catalytic performance of semiconductors. By utilizing the spontaneous polarization of strong ferroelectric materials to induce the separation of electrons and holes, directly developing ferroelectrics as photocatalysts shows great promise. In this study, a ferroelectric layered perovskite Bi4Ti3O12 was prepared through molten salt method (BTO-1) and hydrothermal method (BTO-2), and it exhibits excellent photocatalytic performance for CO2 reduction. Compared to BTO-2, BTO-1 shows stronger photoexcited carrier separation ability and larger specific surface area, leading to significantly higher CH3OH and CH3CH2OH yields. The exceptional ferroelectric properties of BTO-1, resulting from its remarkable crystallinity, effectively reduce the recombination of photogenerated carriers induced by an electric field, thereby greatly enhancing its photocatalytic performance. The yields of CH3OH and CH3CH2OH after CO2 reduction by polarized BTO-1 are 1.84 and 1.61 times higher than those of unpolarized BTO-1, respectively. This study opens up new possibilities for utilizing ferroelectric materials as efficient photocatalysts to improve photocatalytic ability.

Summary: Porous Ni2P was constructed and confirmed to enhance the photocatalytic performance of Ni2P/CdS composite. The porous Ni2P/CdS photocatalyst exhibited higher H2 evolution rate from water and CO and CH4 evolution rates from CO2 reduction compared to the non-porous Ni2P/CdS photocatalyst. The porous structure improved light path and increased light absorption utilization, resulting in enhanced photocurrent intensity and rapid charge transfer. The higher signal of ,O2- radicals in porous Ni2P/CdS contributed to its remarkable photocatalytic activity.

Summary: Photocatalysis using renewable resources like sunlight is an eco-friendly method for reducing greenhouse gases. This study focused on defective ZnO nanoparticles for carbon dioxide adsorption and activation in photocatalytic reactions. The nanoparticles were synthesized by controlling the concentration of NaOH as the precipitating agent. The rough surface of ZnO, formed through heating treatment, effectively removed attached inorganic molecules and was observed using TEM analysis. Optimal defects were achieved by varying NaOH concentrations, resulting in enhanced methane production compared to commercial ZnO. Furthermore, the catalyst demonstrated reusability with only a 7.7% performance reduction after 4 cycles. This study proposes a novel mechanism for CO2 photoreduction using defective ZnO nanoparticles, which could contribute to the long-term sustainability of the industry.

Summary: Chromium-based cocatalysts affect H2 production in the overall water splitting reaction during the photo-catalytic conversion of CO2 with H2O. To understand the mechanism by which chromium species promote or suppress H2 evolution, the reaction was performed with the addition of chromate ions on different photocatalysts. It was observed that chromate ions suppress H2 evolution when the photocatalyst surface is highly protonated.

Summary: Through in situ time-resolved XAS, the dynamic behavior of the formation of two-dimensional low-coordinated Pt particles through reduction of PtOx particles by H2 was observed. The reduction of relatively stabilized PtOx species occurred below 373 K, while the reduction of interfacial PtOx species on the γ-Al2O3 surface occurred above 373 K. The morphology changed from three-dimensional PtOx particles to two-dimensional low-coordinated Pt particles during the in situ reduction of PtOx/Al2O3 at 473 K, while at 373 K, the interfacial PtOx species remained after its reduction. This study demonstrated that in situ time-resolved XAS is one of the most definitive techniques to unveil the MSI effect during the reductive formation process of Pt nanoparticle catalysts loaded on γ-Al2O3.

Summary: Automotive exhaust gases containing harmful gases can be purified using Pd-loaded catalyst, and a material with high oxygen storage performance is crucial for effective purification. Pd/Ca2AlMnO5+8 demonstrates efficient purification of exhaust gases under fluctuating oxygen concentration due to its high oxygen release and storage capacities. The redox properties of the Mn species in Pd/Ca2AlMnO5+8 are responsible for the NO reduction behavior under fluctuating oxygen concentration, as observed from operando and static X-ray absorption fine structure (XAFS) spectra.

Summary: An environmental catalyst was synthesized by substituting a transition metal (Mn, Fe, or Co) into the Ti site of SrTiO3, and its reactivity of lattice oxygen was evaluated. The Mn- and Co-doped SrTiO3 catalysts showed higher activities in CO oxidation compared to Pt/Al2O3 catalysts, despite having lower surface areas. Xray absorption fine structure (XAFS) measurements revealed that the lattice oxygen of Co-doped catalyst was released at the lowest temperature. Isotopic experiments indicated that the lattice oxygen participated in CO oxidation on Fe- and Co-doped catalysts via the Mars-van Krevelen mechanism, while the contribution of lattice oxygen to CO oxidation on Mn-doped catalyst was relatively negligible, following the Langmuir-Hinshelwood mechanism. This paper demonstrates that the catalytic mechanism can be adjusted by substituting transition metals into SrTiO3.

Summary: The optimization of ligand structure in the series of bis(phosphine oxide) and beta-ketophosphine oxide representatives enables efficient coordination of Tb3+ and Eu3+ ions and formation of complexes with high luminescence. The nature of the bridging group between two phosphine oxide moieties greatly affects the coordination mode of the ligands with Tb3+ and Eu3+ ions. The high stability of the tris-complexes allows for their safe conversion into colloids, exhibiting the same luminescence as in solutions. The tris-complexes show a pronounced luminescent response to the antibiotic ceftriaxone, making them suitable for sensing applications.

Summary: Methane pyrolysis, a potential hydrogen production process, can transform CH4 into hydrogen without CO2 byproduct under the net-zero emission target. In this study, a new strategy using Ni foam and molten NaCl-KCl for methane pyrolysis to hydrogen production was proposed. The methane conversion rate was enhanced by increasing the amount of Ni foam, and the process was optimized through different catalyst amounts, height of Ni foam layer, and filling method. The addition of molten salt alleviated carbon deposition deactivation of the Ni foam and maintained its macrostructure.

Summary: By selectively cleaving the C-O bonds in CH3O* intermediates instead of the metal-O bonds, the formation of peroxidation products can be significantly prevented, thus modulating the conversion pathway of methane.

Summary: Methane, as a raw material for the C1 chemical industry, is difficult to convert into more useful hydrocarbons and hydrogen due to thermodynamic limitations. Non-oxidative coupling of methane to produce ethane and hydrogen is a promising supply technology. Progress has been made in designing and applying catalysts, such as thermal and photocatalysts, for this technology. This review outlines typical catalysts, reviews the progress in understanding reaction mechanisms, and presents suggestions for the development of high-selectivity and high-stability catalysts in the future.

Summary: In this study, highly durable dry reforming of methane (DRM) at low temperatures was achieved through the integration of light irradiation and active site engineering. Two targeted reaction paths for the production of the key intermediate (CH3O*) were successfully constructed by fabricating active sites with Ni-O coordination and Ni-Ni coordination, respectively. The operando diffuse reflectance infrared Fourier transform spectroscopy coupled with steady-state isotopic transient kinetic analysis (operando DRIFTS-SSITKA) was used to track the anticoking paths during the DRM process. The findings provide critical insights into the simultaneous achievement of low-temperature and anticoking DRM process.
