However, sluggish charge carrier kinetics remain a significant barrier to effective CO₂ photoreduction. In this study, a solvothermal method is employed to synthesize facet-engineered CeO₂/ZnO nanorod (NRs) S-scheme heterojunctions for the selective photoreduction of CO₂ to methanol under mild conditions. Comprehensive characterization confirms the successful deposition and stability of CeO₂ nanoparticles on the surface of ZnO NRs. Among the synthesized photocatalysts, the composite with 0.2 mmol CeO₂ exhibits the best performance, yielding 111 µmol·g^₋1, 176 µmol·g^₋1, 311 µmol·g^₋1, and 304 µmol·g^₋1·h^₋1 for H₂, CO, CH₄, and CH₃OH, respectively, with a notable CO₂ selectivity of approximately 89 %. Mechanistic analysis reveals that optimized CeO₂ loading induces an internal electric field, facilitating an S-scheme heterojunction charge-transfer pathway that enhances electron mobility from the ZnO NRs to CeO₂. In-situ FT-IR spectroscopy further identifies key intermediates (HCOO* and H₃CO*) involved in the transformation of CO₂ to CH₃OH. This work demonstrates a novel photocatalyst design that leverages precise CeO₂ loading onto ZnO NRs, offering a promising strategy for efficient and selective CO₂ photoreduction.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"27 ","pages":"Article 100781"},"PeriodicalIF":7.5,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the atomic and electronic structures of LWS on rutile TiO₂(001) using ambient atomic force microscopy (AFM), Kelvin probe force microscopy (KPFM), and ultrahigh-vacuum scanning tunneling microscopy (STM).

The diffusivity of NCs significantly influences the thermal transport properties of these composites, yet its effects remain inadequately studied. This study investigates typical nanofluids and colloidal NC superlattices found in NC-based composites. By varying the diffusivity of NCs over eight orders of magnitude, we analyzed its impact using the Green-Kubo equilibrium molecular dynamics (GK-EMD) method. Our findings indicate that when the diffusivity exceeds 10⁻⁵ Ų/ps, it artificially inflates the calculated thermal conductivity (TC) up to 60,000%, requiring a modification to the heat flux formulation to correct. Conversely, when diffusivity is below 10⁻⁵ Ų/ps, it amplifies the fluctuations in the heat flux, leading to greater uncertainty in the results, which can be mitigated using the same heat flux modification. Based on the precise TC results for the two NC-based composites, we demonstrate that the vibrational mismatch between the two fluid layers closest to the NC surface, rather than between the NC surface and the fluid, governs the TC of the nanofluid. Although the diffusivity of NCs in the colloidal NC superlattice increases with temperature, it contributes less than 10% to the total TC at 400 K. Moreover, no evidence was found of collective vibrational modes contributing to thermal transport at low temperatures, contrary to a previous study [Materials Today Physics 22 (2022) 100601].

In all samples, N-face n-GaN surfaces were etched using a 4 M KOH solution after laser lift-off (LLO) process. A 2 min-etching resulted in the formation of pyramids (size: ∼90 – ∼270 nm), while the 4 min-etching produces pyramids (∼370 – ∼780 nm). Regardless of treatments, all samples exhibit similar forward bias characteristics. For all samples, the light output power increased after n-GaN surface roughening.

Analysis of the Sn composition in ZTO films grown by supercycle ALD revealed a higher Sn content than expected based on theoretical predictions. This deviation is examined through in-situ quadrupole mass spectrometer (QMS) monitoring of the diethylzinc (DEZ) ALD reaction byproducts, which indicates variations in reactive site density during the alternating deposition cycles of ZnO and SnO₂. While DEZ adsorption involves a single ethyl ligand exchange, maintaining site density, the tetrakis(dimethylamino)tin (TDMASn) ALD reaction can alter it by changing reactive sites based on dimethylamino (DMA) ligands. The results indicate that increasing the Sn content decreases the number of oxygen vacancies in the films because of the stronger bond strength between Sn and O. Thin-film transistors (TFTs) are fabricated using ZTO films with different Sn compositions, and their electrical properties were evaluated. The results show that increasing the Sn content enhances electron mobility (which reaches a peak value at a specific Sn concentration) and shifts the threshold voltage of the TFTs.
