“…Recently, plasmonic-based heterojunction photocatalysts have attracted enormous attention for organic pollutants degradation [ 61 , 201 , 202 ]. This is due to the remarkable properties of plasmonic-based heterojunction photocatalysts such as (1) effective separation and transfer of photogenerated e − – h + , (2) improvement of stability, and (3) enhancement of light absorption of the photocatalyst [ 92 , 203 ].…”

Organic pollutants in wastewater are the biggest problem facing the world today due to population growth, rapid increase in industrialization, urbanization, and technological advancement. There have been numerous attempts to use conventional wastewater treatment techniques to address the issue of worldwide water contamination. However, conventional wastewater treatment has a number of shortcomings, including high operating costs, low efficiency, difficult preparation, fast recombination of charge carriers, generation of secondary waste, and limited light absorption. Therefore, plasmonic-based heterojunction photocatalysts have attracted much attention as a promising method to reduce organic pollutant problems in water due to their excellent efficiency, low operating cost, ease of fabrication, and environmental friendliness. In addition, plasmonic-based heterojunction photocatalysts contain a local surface plasmon resonance that enhances the performance of photocatalysts by improving light absorption and separation of photoexcited charge carriers. This review summarizes the major plasmonic effects in photocatalysts, including hot electron, local field effect, and photothermal effect, and explains the plasmonic-based heterojunction photocatalysts with five junction systems for the degradation of pollutants. Recent work on the development of plasmonic-based heterojunction photocatalysts for the degradation of various organic pollutants in wastewater is also discussed. Lastly, the conclusions and challenges are briefly described and the direction of future development of heterojunction photocatalysts with plasmonic materials is explored. This review could serve as a guide for the understanding, investigation, and construction of plasmonic-based heterojunction photocatalysts for various organic pollutants degradation. Graphical abstract Herein, the plasmonic effects in photocatalysts, such as hot electrons, local field effect, and photothermal effect, as well as the plasmonic-based heterojunction photocatalysts with five junction systems for the degradation of pollutants are explained. Recent work on plasmonic-based heterojunction photocatalysts for the degradation of various organic pollutants in wastewater such as dyes, pesticides, phenols, and antibiotics is discussed. Challenges and future developments are also described.

The Ce‐doped TiO2 nanoparticles were prepared by the sol–gel method. The prepared nanoparticles were characterized by sophisticated analytical techniques such as XRD, FESEM with EDX, HR‐TEM, XPS, FTIR, TGA, and UV–visible spectroscopy, which gives structural features, morphology, elemental composition, and thermal stability of prepared nanoparticles. Based on the analysis, we conclude that increasing the dopant content of cerium in TiO2 results in a decrease in particle size, increase in thermal stability, and decrease in band gap. Further, on increasing the dopant content of cerium, there is an increase in photocatalytic activity due to changes in structural features due to doping, and 5 mol% Ce‐doped TiO2 has shown nearly four times higher photocatalytic activity than pure TiO2 for degradation of tetracycline. In this study, the photocatalytic activity and kinetics of photocatalytic degradation of antibacterial agent tetracycline have been studied by using these prepared catalysts. Further, effects of different parameters such as change in pH and change in concentration of tetracycline and amount of catalyst loading have been studied for the degradation of tetracycline. Also, Ce‐doped TiO2 has shown good photocatalytic efficiency for degradation of a mixture of textile dyes (methylene blue, rhodamine B, and brilliant green) and for degradation of a mixture of emerging contaminants (tetracycline, diclofenac, and triclosan).

Surface Pretreatments of AA5083 Aluminum Alloy with Enhanced Corrosion Protection for Cerium-Based Conversion Coatings Application: Combined Experimental and Computational Analysis

et al. 2021

The effects of surface pretreatments on the cerium-based conversion coating applied on an AA5083 aluminum alloy were investigated using a combination of scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), polarization testing, and electrochemical impedance spectroscopy. Two steps of pretreatments containing acidic or alkaline solutions were applied to the surface to study the effects of surface pretreatments. Among the pretreated samples, the sample prepared by the pretreatment of the alkaline solution then acid washing presented higher corrosion protection (~3 orders of magnitude higher than the sample without pretreatment). This pretreatment provided a more active surface for the deposition of the cerium layer and provided a more suitable substrate for film formation, and made a more uniform film. The surface morphology of samples confirmed that the best surface coverage was presented by alkaline solution then acid washing pretreatment. The presence of cerium in the (EDS) analysis demonstrated that pretreatment with the alkaline solution then acid washing resulted in a higher deposition of the cerium layer on the aluminum surface. After selecting the best surface pretreatment, various deposition times of cerium baths were investigated. The best deposition time was achieved at 10 min, and after this critical time, a cracked film formed on the surface that could not be protective. The corrosion resistance of cerium-based conversion coatings obtained by electrochemical tests were used for training three computational techniques (artificial neural network (ANN), adaptive neuro-fuzzy inference system (ANFIS), and support vector machine regression (SVMR)) based on Pretreatment-1 (acidic or alkaline cleaning: pH (1)), Pretreatment-2 (acidic or alkaline cleaning: pH (2)), and deposition time in the cerium bath as an input. Various statistical criteria showed that the ANFIS model (R2 = 0.99, MSE = 48.83, and MAE = 3.49) could forecast the corrosion behavior of a cerium-based conversion coating more accurately than other models. Finally, due to the robust performance of ANFIS in modeling, the effect of each parameter was studied.
