Topic Information

Dear Colleagues,

Surface and interface engineering is one of the most important and exciting fields in catalytic and optoelectronic chemistry and device applications. In a typical heterogeneous catalyst, surface and interface engineering is an effective approach to enhance reaction activity. In addition, since surfaces and interfaces play pivotal roles in diverse fields such as catalysis, electronics, sensors, and photonics, their use has increased over the recent years in industrial, semiconductors, and optoelectronic applications, with significant impact. Furthermore, with advances in nano- and angstrom technologies, catalysts have become increasingly important regarding surfaces and interface properties, contributing to the improvement of a variety of properties in materials. This topic aims to integrate and present the latest advances to inspire and inform researchers in the field of biomembranes, oxide films, semiconductor nanorods/wires, metal alloys, and composites. The topics of interest for this project include (but are not restricted to):

  • Synthesis and applications of nanocomposites based on nitride/oxide nanomaterials and photovoltaic materials; 
  • Synthesis and applications of 2D TMDC materials containing carbon-based nanocomposites;
  • Advanced optical and electronic properties of nanocomposites;
  • Application of advanced nanocomposites in catalysis and optoelectronics;
  • Surface and interface engineering of materials for photocatalytic and optoelectronic applications;
  • The impact of surface morphology and interface defects;
  • Superior optoelectronic properties in devices of high-quality materials.

Abstract
A metal oxide-based interconnecting and window layer consisting of a molybdenum oxide (MoO3)/Zn-doped In2O3 (IZO) bilayer was investigated in efficient solution-processed perovskite/n-Si monolithic tandem solar cells using formamidinium cesium lead triiodide, FA0.9Cs0.1PbI3, [...] Read more.
A metal oxide-based interconnecting and window layer consisting of a molybdenum oxide (MoO3)/Zn-doped In2O3 (IZO) bilayer was investigated in efficient solution-processed perovskite/n-Si monolithic tandem solar cells using formamidinium cesium lead triiodide, FA0.9Cs0.1PbI3, and poly(3,4-ethylenedioxythiophene)/poly(polystyrene sulfonate) (PEDOT:PSS). The MoO3/IZO bilayer with and without Au nanoparticle play a significant role in the charge extraction and recombination within the interconnecting layer and the window layer of the top cell, respectively. A power conversion efficiency of 18–19% was achieved with a short-circuit current, Jsc, of 17.8 mA/cm2; an open-circuit voltage, Voc, of 1.48 V; and an FF of 0.74 by adjusting the layer thicknesses of MoO3 (5 nm), Au nanoparticle layer (5 nm), and sputtered IZO (42 nm for ICL and 80 nm for window layer).

Cordierite-based supported noble-metal-free catalysts for ozone decomposition are elaborated. The cordierite ceramic surface is pretreated with oxalic acid and NaOH, and Mn-Cu-Ni oxide catalysts are prepared by the impregnation method. The mass ratio of the supported oxides in the resulting catalysts is MnO2:CuO:NiO = 3:2:1, and their loadings are from 1.8 to 7.0 wt.%. The pretreated supports and catalysts are characterized by low-temperature N2 adsorption, scanning electron microscopy (SEM), powder X-ray diffraction analysis (XRD), and temperature-programmed reduction with H2 (TPR-H2). The catalysts are tested in ozone decomposition with high airflow rates (20 and 50 L/min) and with initial ozone concentrations of 1 and 2 ppm at temperatures in the range of 25–120 °C. It is shown that a combined treatment of cordierite with oxalic acid and NaOH leads to a developed porous structure and stabilization of supported Mn-Cu-Ni oxides in a highly dispersed state. The high activity of catalysts in ozone decomposition at room temperature and high airflow is demonstrated. The developed catalysts can be recommended for application in purification of air from the ozone because of their high catalytic activity, high mechanical stability, and relatively low weight and cost.

In this study, the effects of annealing on the surface residual impurities and intrinsic defects of unintentionally doped (UID) β-Ga2O3 are investigated by adopting high-temperature thermal treatments at 1000 °C for 1 h under vacuum and O2 ambience. It is found that the recovery between the divacancies VGa+VO and interstitials (Oi) occurs during annealing, and the residual impurities are identified as Si and Cr, which are repelled toward the surface during annealing. Interestingly, these impurities occupy the formation of Ga vacancies (VGa) near the surface formed by oxygen annealing, consequently weakening the relevant impurity scattering and improving carrier mobility. Moreover, the carrier density of the samples is explored using temperature-dependent Hall measurements, which show a slight reduction in both vacuum and oxygen annealing. This reduction might be a result of the VGa pushing the Fermi level away from the conduction band. In addition, the activation energy of Si ions occupying VGa(I) is lower than that of the interstitial Si ions. Full article
