“…When the concentrations of NO 2 are 10, 20, 30, 40 and 50 ppm, the response intensity increase to 14.8, 20.6, 26.1, 31.2 and 32.6. The response value of the sample to 60 ppm NO 2 is as high as 33.6, which is superior than those from most of the reported Cu 2 O‐based NO 2 gas sensing materials [9–12, 27, 28], as summarized in Table 1. Moreover, NO 2 gas sensing performances of the recently reported p‐type metal oxides [29–34] have also been summarized in Table S1.…”

In this work, fabrication of Cu 2 O@Cu 1.75 S coreshell octahedrons was achieved through a facile water bath stirring process. Compared with pure Cu 2 O, the composite showed enhanced sensing performance for NO 2 . The response value of Cu 2 O@Cu 1.75 S to 5 ppm NO 2 at 40 °C is seven times that of Cu 2 O to 5 ppm NO 2 at 75 °C. Moreover, Cu 2 O@Cu 1.75 S has the ability to detect 100 ppb NO 2 and has good NO 2 sensing selectivity and long-term stability. This study shows that Cu 2 O@Cu 1.75 S hybrid is a type of outstanding NO 2 gas sensing material on account of its low working temperature and high sensing sensitivity.

“…One of the most widely used approaches to increasing the sensitivity of sensors is the preparation of active layers with a porous structure. In this connection, hybrid materials of metal phthalocyanines with carbon nanomaterials [6,81], oxides [82,83], polymeric membranes [84], and silica matrix [85] are very promising due to their high surface area-tovolume ratio. Some of them were successfully used in SPR sensors.…”

In this review, the state of research over the past fifteen years in the field of the applications of metal phthalocyanines and porphyrin derivatives as well as their hybrid materials with carbon nanotubes, metal oxides, and polymers in optical sensors based on the phenomenon of surface plasmon resonance (SPR) is analyzed. The first chapter of the review presents an analysis of works on the use of porphyrins and phthalocyanines in classical SPR sensors for the detection of gases and volatile organic vapors, as well as their improved modifications, such as total internal reflection ellipsometry (TIRE) and magneto-optical SPR (MOSPR) methods, while the second chapter is devoted to their application for the detection of various analytes in solutions. The third chapter of the review summarizes publications describing recent advances in the use of porous materials based on hybrids of carbon nanotubes and oxides with metal phthalocyanines. The fourth chapter describes two-dimensional metal-organic frameworks (MOFs) based on metal porphyrin derivatives as SPR sensitizers.

“…As indicated above, numerous research efforts have focused on tuning the nanostructure and function of copper oxide-based materials by anodization, which has led to the discovery of many fascinating properties and applications. In addition to the PEC and supercapacitor applications commonly encountered, copper oxide-based materials have found applications in sensors [43,109,119,127,128] , pH-controllable water permeation [93] , superhydrophobic anticorrosion coatings [94,95,129] , oil/water separation [122] and surface-enhanced Raman scattering substrates [108] .…”

Nanostructured anodic films on transition metals prepared using the electrochemical anodization method have recently attracted particular attention owing to their extraordinary properties and potential use in a variety of applications. Herein, we provide a thorough review of the anodization fabrication of anodic films with different nanostructures, including nanopores, nanotubes, nanoflowers, nanoneedles and nanowires on transition metals, focusing on the growth processes of nanostructured anodic films on three representative transition metals, namely, iron, copper and zinc. Specific consideration is given to the anodization behavior and formed film nanostructures of these transition metals. We conclude that electrolyte composition plays a key role in influencing the final morphologies of anodic films. Fluoride-containing solutions represent universal electrolytes for forming nanostructured anodic films on transition metals. The main applications of the resulting nanostructured anodic films, especially in energy-related fields, such as photoelectrochemical water splitting and supercapacitors, are also presented and discussed. Finally, we indicate the main challenges associated with the fabrication of anodic films with highly ordered nanostructures and the potential future directions of this field are indicated.
