“…The Bode plots in Figure 6f show that TNRs and H-TNRs have two peaks, whereas the others have three peaks, which could be assigned to the microstructure differences. [65] Therefore, TNRs and H-TNRs with 1D nanorod morphology have two-time-constant, and A-H-TNRs and CAHT NRs films with 3D anatase branches have three-time-constants. Models of equivalent circuits for EIS results are displayed in Figure 6g.…”

“…While significant advancements have been made in structural materials, in terms of their mechanical properties, their ability to perform and withstand corrosion remains a particular challenge. As a photocatalyst, g-C 3 N 4 is attracting considerable attention [208], and it has been studied and successfully employed in the photocathodic protection of SS316 and Q235 [209], Q235 CS [210] and SS 304 [75]. It has a relatively high charge carrier recombination rate, and therefore it is mostly combined with other semiconductors to create heterostructures.…”

“…Other heterojunctions, including ZnO/g-C 3 N 4 [211] and In 2 O 3 /g-C 3 N 4 [212], have been utilized in photocathodic protection. Interestingly, Zhang et al [209] formed g-C 3 N 4 n-n homojunction films on indium tin oxide substrates. With the optimum photocathodic protection, photocurrents of 143.44 µA cm −2 and 111.48 µA cm −2 were observed for SS316 and Q235, and the potentials were lowered to −982 mV and −1081 mV, well into the immune region for SS316 and Q235.…”

Emerging Layered Materials and Their Applications in the Corrosion Protection of Metals and Alloys

Metals and alloys are essential in modern society, and are used in our daily activities. However, they are prone to corrosion, with the conversion of the metal/alloy to its more thermodynamically-favored oxide/hydroxide phase. These undesirable corrosion reactions can lead to the failure of metallic components. Consequently, corrosion-protective technologies are now more important than ever, as it is essential to reduce the waste of valuable resources. In this review, we consider the role of emerging 2D materials and layered materials in the development of a corrosion protection strategy. In particular, we focus on the materials beyond graphene, and consider the role of transition metal dichalcogenides, such as MoS2, MXenes, layered double hydroxides, hexagonal boron nitride and graphitic carbon nitride in the formulation of effective and protective films and coatings. Following a short introduction to the synthesis and exfoliation of the layered materials, their role in corrosion protection is described and discussed. Finally, we discuss the future applications of these 2D materials in corrosion protection.

Enhanced Gas Sensing Performance of Nano‐Structured Ta₂O₅‐SnO₂ Composite for Low Concentration CO Detection

et al. 2022

In the present work, the superior performance of nanostructured Ta 2 O 5 -SnO 2 nanocomposite homo-junction was demonstrated for the detection of CO gas at low concentration (5-10 ppm) and low operating temperature (50 °C). The gas sensing performance of this material is comparable to the state of the art materials reported to date in the literature. In addition, the material exhibits high selectivity to CO gas over other interfering gases such as CO 2 , H 2 , CH 4 , NO 2 , and SO 2 etc. The sensing performance of the composite was significantly higher than its individual oxides. The composite is robust and shows good reproducibility and chemical stability with low response and recovery time. The strategy employed herein to create homo-junction nanocomposites of semiconducting metal oxides significantly improved the sensitivity and selectivity to CO gas closer to room temperature and thus could pave the way for the development of efficient homo-junction nanocomposites for gas sensing applications.
